The Evolution FAQ.
I was considering writing my own FAQ on evolution until I came across this one that is already finished and of a very high quality. I would like to emphasize that although evolution is a fact not a theory it has no relevance to a belief or disbelief in God. Indeed God(s) may use the process of evolution . Please read the following carefully and digest what it says rather than what you may want it to say. This is a truly excellent article; please enjoy and learn. The realization that evolution is a fact is indeed a life changing experience for many, but does not have to be a negative one and in no way disproves the existence of God rather just demonstrates the overwhelming evidence that life evolved through the process of natural selection.
Enjoy the article.

The Evolution Fact FAQ
M. R. Leipzig (c)1997-1998
Last revision 27 January, 1998
If one is to surf the web today and try and make
some sort of sense of the bewildering array of information (running the
Gardnerian gamut of 'good, bad and bogus') so easily available there; one can
become quickly mired in the voluminous mainstream scientific and
less-than-mainstream pseudoscientific terminology, arguments and contentions. As
an attempt to hopefully help 'clear the muddied waters', level the playing field
(I speak hopefully, although not terribly optimistically, that this can be
accomplished without the use of explosives; verbal or otherwise) and turn some
of the intensely emotive partisan friction of the Creation/Evolution issue into
light, I offer the following:
What is Evolution? (and, more importantly, what is
not evolution.)
Before we proceed, it is essential that we set a
few ground rules and delimit exactly to what we are referring when we speak of
evolution in the context of the evolution\creation conflict. Thus: by
definition, evolution is: (1.) precisely defined as any change in the frequency
of alleles within a gene pool from one generation to the next. The gene pool is
the set of all genes in a species or population. This is the neontological
(biological) definition.
Unfortunately, alleles themselves are rarely, if
ever, preserved in the rock record as fossils; which are the key data units in
the examination of the history of life on Earth. But, the expression of these
alleles is preserved in the fossils of populations of organisms, which are
readily available for examination. From this, it is readily apparent that (2.)
life has developed (not 'progressed') from one or a small set of common
ancestors as well as from 'simple' organisms to more 'complex' creatures over
the span of geological time. This is one of the paleontological definitions of
evolution.
Although already there may be some dissenters
bristling over the relative merits of biological 'simplicity' or 'complexity'; I
maintain that, in however a general or specific sense, a multicellular organism
(say, a human, a blue whale, or a Velociraptor mongoliensis) is relatively more
complex (systemically) than a unicellular blue-green alga; although I will
concede that complexity is not a measure of a population of organisms success
(viz.: bacteria and alga are much more voluminous and have been extant far
longer than Homo sapiens), but is used here solely for purposes of
differentiation between the neontological and paleontological concept of
evolution.
Therefore, with these definitions in mind;
evolution:
1.
is a fact,
2.
is also a number of theories,
3.
is Science,
4.
is also scientific,
5.
is naturalistic and purely mechanistic,
6.
is falsifiable,
7.
is testable,
8.
is predictive,
9.
has been observed;
9a. in the field
9b. in the laboratory,
10.
has occurred in the past,
11.
is still occurring,
12.
will continue to occur in the future.
Further,
we can also note that evolution:
13.
is not atheistic (nor Communistic, Marxist, Leninist, Stalinist, etc.),
14.
is not evil,
15.
is not mandated by law to be taught in US public schools,
16.
is not a cosmological theory (i.e., "it don't do origins"),
17.
is not a religion nor Religion,
18.
is not determined by popular opinion (as can be said of any science),
19.
is not a socio-political program or paradigm,
20.
is not dependent on the supernatural,
21.
does not claim that "Man came from apes",
22.
is not progress,
23.
has not, will not and cannot be proven (as can be said of any science),
24.
Is not random nor relies on 'blind chance',
25.
does not violate the second law of thermodynamics,
26.
Does not deny (a) God(s), and finally,
27.
Falsifying evolution does not prove Creation.
That said, let us examine every claim in turn and
in detail that evolution:
1. is a fact,
"It
is time for students of the evolutionary process, especially those who have been
misquoted and used by the creationists, to state clearly that evolution is a
FACT, not ("only a" - ed.) theory, and that what is at issue within
biology are q questions of details of the process and the relative importance of
different mechanisms of evolution.
It is a FACT that the earth with liquid water, is
more than 3.6 billion years old. It is a FACT that cellular life has been around
for at least half of that period and that organized multicellular life is at
least 800 million years old. It is a FACT that major life forms now on earth
were not at all represented in the past. There were no birds or mammals 250
million years ago. It is a FACT that major life forms of the past are no longer
living. There used to be dinosaurs and Pithecanthropus, and there are none now.
It is a FACT that all living forms come from previous living forms.
Therefore, all present forms of life arose from
ancestral forms that were different. Birds arose from nonbirds and humans from
nonhumans. No person who pretends to any understanding of the natural world can
deny these facts any more than she or he can deny that the earth is round,
rotates on its axis, and revolves around the sun.
The controversies about evolution lie in the realm
of the relative importance of various forces in molding evolution."
- R. C. Lewontin "Evolution/Creation Debate: A
Time for Truth" Bioscience 31, 559 (1981).
Just as much as gravitation is a fact, is so
evolution. It has been observed, in both the laboratory and the field, and
through the evidence of the fossil record. It is not debated in mainstream
science that evolution has occurred (and is still occurring); but it is the mode
and tempo of evolution that is being debated.
2. is also a number of theories,
Even before the time of it's formal introduction to
science by Darwin, there have been many differing and different theories
advanced to explain the fact of organic evolution and the diversity of life on
Earth. Some are over 100 years old, while others are quite recent innovations.
Some have been discarded as erroneous, while others have, literally and
figuratively, tons of evidence which support them.
A general listing of these theories include
Darwinism (descent with modification by natural selection; and in and of itself
a set of theories; i.e., 'Strict Darwinism', 'General Darwinism', etc.; and an
'umbrella' term sometimes used in other evolutionary theories as a basis, which
is then modified), Lamarckianism ("inheritance of acquired
characteristics"), saltationalism (evolution proceeding by major leaps or
jumps), gradualism (slow, uniform accumulation of modifications), punctuated equilibrium
(periods of stasis followed by brief, intense periods of speciation), phyletic
gradualism (speciation occurs gradually over a species' entire range),
orthogenesis (evolution that follows a single direction or specific trend
continuously, "straight- line" evolution, often appearing to be
independent of natural selection), creationism (a religious, non-scientific,
pseudoscientific preconceived dogmatic construct), etc.
With the exception of creationism ('Scientific',
Biblical or otherwise), the remainder are or were scientific theories.
Orthogenesis, Lamarckianism, saltationalism (to a certain degree), and
creationism have been largely been abandoned or supplanted by other theories or
combination of theories. In fact, the union of molecular biology, genetics and
natural selection (Darwinism) lead to what is known as the Modern Synthesis.
That is, the Modern Synthesis is a theory about how evolution works at the level
of genes, phenotypes, and populations whereas Darwinism was concerned mainly
with organisms, speciation and individuals.
One of the most recent, and generally least
understood, theories of evolution is Punctuated equilibrium:
Some paleontologists think evolution is a
hierarchical process.
The theory of punctuated equilibrium attempts to
infer the process of macroevolution from the pattern of species documented in
the fossil record. In the fossil record, transition from one species to another
is usually abrupt in most geographic locales -- no transitional forms are found.
In short, it appears that species remain unchanged for long stretches of time
and then are quickly replaced by new species. However, if wide ranges are
searched, transitional forms that bridge the gap between the two species are
sometime found in small, localized areas.
For example, in Jurassic brachiopods of the genus
Kutchithyris, K. acutiplicata appears below another species, K. euryptycha. Both
species were common and covered a wide geographical area. They differ enough
that some have argued they should be in n a different genera. In just one small
locality an approximately 1.25m sedimentary layer with these fossils is found.
In the narrow (10 cm) layer that separates the two species, both species are
found along with transitional forms. In other localities there is a sharp
transition.
Gould and Eldredge, the authors of punctuated
equilibria, interpret this in light of theories of allopatric speciation. They
concluded that isolated populations of organisms will often speciate and then
invade the range of their ancestral species. Thus us at most locations that
fossils are found, transition from one species to another will be abrupt. This
abrupt change will reflect replacement by migration however, not evolution. In
order to find the transitional fossils, the area of speciation must be found.
They also argue that evolution can proceed quickly
in small populations so that the tempo of evolution is not continuous. This has
lead to some confusion about the theory. Some popular accounts give the
impression that abrupt changes in the fossil record are due to blindingly fast
evolution; this is not what the theory of punctuated equilibria says.
Some PE proponents envision the theory as a
hierarchical theory of evolution because they see speciation as analogous to
mutation and the replacement of one species by another (which they call species
selection) as analogous to natural selection. Speciation adds new species to the
species pool just as mutation adds new alleles to the gene pool and species
selection favors one species over another just as natural selection can favor
one allele over another. This is the most controversial part o f the theory.
Most biologists agree with the pattern of macroevolution these paleontologists
posit, but many disagree with the mechanism -- species selection. Critics would
argue that species selection is not analogous to natural selection and there
fore evolution is not hierarchical.
The theory of punctuated equilibrium was designed
to replace the theory of phyletic gradualism (here, in and of itself, is a
type-section instance of scientific nature of evolution: testing, re-analysis,
re- interpretation and self-correction in action). Phyletic gradualists held
that a species would slowly transform into another species over its entire
range. Phyletic gradualism is often associated with the assumption of a uniform
rate of evolution, but this need not be the case.
Although all this fact vs. theory exposition may
seem a tad confusing, here's a concise binary clarification courtesy of
Harvard's own Stephan Jay Gould:
"Well
evolution is a theory. It is also a fact. And facts and theories are different
things, not rungs in a hierarchy of increasing certainty. Facts are the world's
data. Theories are structures of ideas that explain and interpret facts. Facts
don't go away when scientists debate rival theories to explain them. Einstein's
theory of gravitation replaced Newton's in this century, but apples didn't
suspend themselves in mid-air, pending the outcome. And humans evolved from
ape-like ancestors whether they did so by Darwin's proposed mechanism or by some
other yet to be discovered.
"Moreover, 'fact' doesn't mean 'absolute
certainty'; there ain't no such animal in an exciting and complex world. The
final proofs of logic and mathematics flow deductively from stated premises and
achieve certainty only because they are NOT about the empirical world.
Evolutionists make no claim for perpetual truth, though creationists often do
(and then attack us falsely for a style of argument that they themselves favor).
In science 'fact' can only mean 'confirmed to such a degree that it would be
perverse to withhold provisional consent'. I suppose that apples might start to
rise tomorrow, but the possibility does not merit equal time in physics
classrooms.
"Evolutionists have been very clear about this
distinction of fact and theory from the very beginning, if only because we have
always acknowledged how far we are from completely understanding the mechanisms
(theory) by which evolution (fact) occurred. Darwin continually emphasized the
difference between his two great and separate accomplishments: establishing the
fact of evolution, and proposing a theory - natural selection - to explain the
mechanism of evolution."
- Stephen J. Gould, "Evolution as Fact and
Theory"; Discover, May 1981
3. is Science,
By definition, science (apart from being defined by
definition) is:
| 1.a.
The observation, identification, description, experimental investigation,
and theoretical explanation of natural phenomena. | |
| 1.b.
Such activity restricted to a class of natural phenomena. | |
| 1.c.
Such activity applied to any class of phenomena. | |
| 2.
Methodological activity, discipline, or study. | |
| 3.
An activity that requires study and methodological approach. | |
| 4.
Knowledge, esp. knowledge gained through experience. |
By all aspects of the definition, evolution is
science.
4. is also scientific,
Let's take a quick look at the scientific method
and see just how evolution stacks up:
| *
Empirical They are based on actual experience. Evolution has been observed, in both the laboratory and the field. |
1 for 1 so far.
| *
Rational It follows the rules of logic and is consistent with known facts. Evolutionary theories must be logical (or they are disposed of) and are consistent with, and modifiable by, the addition of new information. |
2 for 2.
| *
Testable You can verify them by experimentation. It is possible to imagine ways that they prove to be invalid. Yes, indeed. See #'s 6 & 7 for further exposition on this topic. |
3 for 3.
| *
Parsimonious They tend not to be complex, to involve fewer assumptions. By application of the Razor of Ockham, the 'principle of parsimony', or the 'KISS' principle (Keep It Simple, Stupid). |
4 for 4.
| *
General They work for a relatively wide range of phenomena. Organic evolution unites biology (neontology), molecular biology, zoology, genetics, geology, paleontology, physical chemistry, physics, etc. I'd consider that a 'relatively wide range of phenomena'. |
5 for 5.
| *
Tentative You are willing to give them up if they prove wrong. Has been done and continues to be done. Lamarkianism, Creationism (special, 'Scientific', Biblical, Qu'ranic, Talmudic, Vedic, or otherwise), and orthogenesis are examples of unsuccessful attempts to define and describe the diversity of life on Earth. |
That's 6 for 6. A perfect
score.
Therefore, evolution is addressable and able to be
investigated by the scientific method; is internally consistent, physically
evidenced, observable (either directly or through the fossil record), is self-
testing and self-correcting.
As evolution is both fact and theory; evolution is
both science and scientific.
5. is naturalistic and purely mechanistic,
Invokes no God(s) nor supernatural constructs in
its explanations. It is constrained by the natural laws of chemistry and physics
and does not proceed randomly. Further, evolution and evolutionary theories all
contain exactly less than one miracle and less than one God.
6. is falsifiable,
Evolution is scientific because it is falsifiable.
Unlike creationism, where no test, no procedure, no gedanken experiment, can be
postulated to disprove the notion of special creation or a creator; which is a
belief system based on faith. Evolution, on the other hand, being based entirely
upon facts and evidence, and which makes statements derived from those facts,
can be falsified. Viz.: find a fossilized skeleton of Homo sapiens in an
undisturbed stratigraphic sequence at the same level as a Tyrannosaur.
Evolutionary theory maintains that: 1. Tyrannosaurs
are extinct, 2. They existed in the Cretaceous period of the Mesozoic era and 3.
Are never found in rocks younger than approximately 66.6 MY (million years) old.
Evolutionary theory also holds that Homo sapiens is a relatively recent addition
to the biological sphere (if you look at the history of life on Earth from a
geological standpoint), is currently extant and whose remains are never found in
sediments greater than approximately 4 MY. Therefore, if one were to be found in
an undisturbed section cheek-by-jowl with a T. rex...
7. is testable,
That is, evolutionary theory can be given to
'what-if' scenarios. For instance, if I happen upon an environment (some may
think this a frivolous notion; but not at all. In recent years life- bearing
environments have been found that were previously thought to be antagonistic to
life, i.e., deep-sea vents on the ocean ridges, which were found to be teeming
with, admittedly unusual, life), I can propose the test of which organisms I
would expect to find there. Conversely, given an organism (extant or extinct)
and it's adaptations; I can, through evolutionary theory, deduce the environment
to which it is best suited.
For instance, let's look at the fossil record. If I
find the remains of an organism, let's say one with wings; I can put it to the
test that it was a flying organism. But, if I find that the wings are heavily
modified and the theoretically-flying creature's remains are always found with
fossil fish fragments and cephalopod pens; and the geology of the depositional
environments indicate a cold, polar fringing-marine environment; my test would
have failed. Seems they winged creatures are m ore well adapted to a pelagic,
nektonic, open marine lifestyle (at least for part of the time). I am forced to
develop another hypothesis and test that (this time in favour of organisms that
'fly' through the water). The hallmark of science is it's testability,
re-analysis, re-interpretation and self-correcting nature. (BTW, if you haven't
already guessed, I was talking about Aptenodytes patigonica.)
8. is predictive,
Logical outcome of item 7. Organisms can be used to
predict their environment and environments can be used to predict the type of
organism that could best exploit that portion of ecological hyperspace.
9. has been observed,
| 9a.
in the field |
In the genus Tragopogon (a
plant genus consisting mostly of diploids), two new species (T. mirus and T.
miscellus) have evolved within the past 50-60 years. The new species are
allopolyploid descendants of two separate diploid parent species.
Here is how this speciation
occurred. The new species were formed when one diploid species fertilised a
different diploid species and produced a tetraploid offspring. This tetraploid
offspring could not fertilize or be fertilised by either of its two parent
species types. It is reproductively isolated, the very definition of a species.
Mammals:
Rapid speciation of the
Faeroe Island house mouse occurred less than 250 years after humans brought it
to the island. Species identification in this case was based on morphology,
since breeding experiments could not be performed with the parent stock . (S.
Stanley, Macroevolution: Pattern and Process, San Francisco: W. H. Freeman &
Company, 1979, p. 41)
Birds:
During a series of natural
catastrophes, the Galapagos island finch- species Geospitza fortis developed a
larger beak, necessary for consuming a variety of seed unaffected by the
ravages. This was a new phenotype never observed before, made manifest i n just
a few years time.
| 9b.
in the laboratory |
Plants:
In 1905, while studying the
genetics of the evening primrose, Oenothera lamarckiana, H. De Vries discovered
among his plants a variant having a different chromosome number. He was unable
to breed this variant with O. lamarckiana. He named the new species O. gigas.
(De Vries, Species and Varieties, Their Origin By Mutation, 1905)
In 1973, L. D. Gottlieb
documented the speciation of Stephanomeira malheurensis from a large population
of S. exigua in Harney County, Oregon. He was able to document morphological
differences in five characteristics plus chromosomal differences. Attempts at
crossbreeding these plants produced hybrids having either scant seeds and
pollen, or developmental abnormalities. (American Journal of Botany 60, pp.
545-553)
After five years of
selective crossbreeding, E. Pasterniani in 1969 produced almost complete
reproductive isolation between two varieties of corn. The species were
distinguishable by seed color, white versus yellow. Other genetic markers
allowed him to identify hybrids, which were not used for future breeding. (Zea
mays L. Evolution 23, pp. 534547)
Insects:
There is a lot of
literature about speciation in fruit flies and house flies. Different
experiments have been carried out to examine separately the effects of natural
selection and genetic drift. See, for example, J. Ringo, et. al, "An
experiment testing two hypotheses of speciation," The American Naturalist
(1989) 126, pp. 642661, or A. B. Soans, et. al, "Evolution of reproductive
isolation in allopatric and sympatric populations," The American Naturalist
(1974) 108, pp. 117- 124.
Tropical fish:
The question can be asked,
is the sex ratio then just a non-adaptive consequence of the independent
assortment of X and Y chromosomes in male sperm? Or, is the ratio adaptive and
Mendelian assortment an adaptive trait that has evolved?
The authors of a recent
paper put this to the test by studying the Atlantic silverside fish Menidia
menidia . This fish has an unusual life cycle in that, during the early months
of the year mostly female offspring are produced. In the summer months mostly
males are produced. The bias in the sex of the offspring is induced by the water
temperature. Female offspring are produced while the water is cold, males while
it is warm. The sex ratio across the whole year balances out to 0.5. This sex
bias is caused by temperature dependent sex determination, not temperature
dependent sex mortality. In other words cold water makes baby female fish form,
it doesn't kill male baby fish. The same embryo could be male or female
depending on the temperature it is raised at (i.e. Mendelian segregation does
not influence the sex ratio in this species.)
The authors captured
hundreds of these fish and maintained them in aquaria for five to six years.
Some aquaria were maintained at low temperatures, others at high temperatures.
In the low temp aquaria, the populations began with mostly females. The sex
ratio, for example, in one low temp tank was 0.70 (70% female) In the high
temperature aquaria, the populations began with mostly males. In one of the low
tanks the sex ratio was 0.18. Both of these, given the population sizes, are
significantly different than 0.50.
As the experiment
progressed, the sex ratios changed from the highly skewed initial conditions. In
all the populations the sex ratios converged on 0.5. The trajectory of the sex
ratios converging on 0.5 differed between many of the tanks. In one tank, the
next and all subsequent generations were at an 0.5 sex ration. In another, it
slowly converged upon 0.5. In yet another it reached 0.5, then overshot
slightly, then returned. This indicates that a sex ratio of 0.5 is somehow
adaptive be cause the fish evolved from a skewed ratio to a balanced ratio.
Since chromosome assortment does not determine sex in these fish (temperature
does), the only explanation for their convergence to 0.5 is natural selection
favoured fish that produced an abnormal amount of the minority sex. (If males
are lacking, any fish that produces male fish will contribute more than average
to the gene pool).
This is a
frequency-dependent kind of selection. As the sex ratio approaches 0.5, fish who
produce a disproportionate amount of either sex will contribute less than
average to the gene pool.
Finally, notice that evolution has occurred. The
experiment started with populations of fish that produced skewed sex ratios and
ended with populations that produced balanced sex ratios. Since the environment
was held constant, the change in the populations was therefore genetic. In other
words, the gene pool changed over time. This is the definition of evolution.
Conover and Voorhees, 1990, Evolution of a Balanced
Sex Ratio by Frequency-Dependent Selection in a Fish, Science 250: p.1556-1558
10. has occurred in the past,
In the July 13, 1990 issue of Science, Gingerich
et. al. report on an interesting fossil found in Egypt. It is a whale with feet.
The skeleton is of the species Basilosaurus isis.
Current cetacea do not have external hind limbs.
But whales, which are mammals, evolved from terrestrial mammals. This fossil,
therefore, is a link between the two. The skeleton they show is long (16 m) and
serpentine. The authors believe th is whale hunted in shallow mangrove or
seagrass habitat. It's hind limb has a short femur and a slightly shorter fibula
and tibia. It has no thumb and a greatly reduced second digit. The other three
fingers are quite long (relatively). In short, another variation of the basic
mammalian leg.
The authors speculate that the limbs were tucked in
close to the body while the whale was swimming (and the osteology of the bones
suggest that they are correct).
Gingerich, et. el., 1990, Hind Limbs of Eocene
Basilosaurus : Evidence of Feet in Whales, Science 249: p.154-156
11. is still occurring,
Yes, evolution is still occurring; all organisms
continue to adapt to their surroundings and "invent" new ways of
better competing with members of their own species. In addition, allele
frequencies are being changed by drift, mutation and gene flow constantly.
Studying the process of evolution as it continues to occur is a major field of
biology today. Although evolution has been observed and all the mechanisms have
been shown to work, there is still no consensus on the relative contribution of
each of the mechanisms to the overall pattern of evolution within a lineage.
12. will continue to occur in the future,
As noted by pre-eminent geologist James Hutton:
"The present is the key to the past". Although Hutton's axiom is
strictly uniformitarian, the premise is valid. Therefore, logically, today's
present is tomorrow's past. What we see in the lab and the field regarding the
fact of evolution today indicates that it will continue into the future as it
has for the last 3.65 BY.
In addition, we can also note that evolution:
13. is not atheistic (nor Communistic, Marxist,
Leninist, Stalinistic, etc.),
"Evolution
is thus not only anti-Biblical and anti-Christian, but it is utterly
unscientific and impossible as well. But it has served effectively as the
pseudo-scientific basis of atheism, agnosticism, socialism, fascism, and
numerous other false and dangerous philosophies over the past century."
Morris, Henry M. and Robert T. Clark. 1976. The
Bible Has the Answers. San Diego: Creation-Life Publishers.
Morris and Clark's brutum fulmen aside, evolution
is about as atheistic as World League Soccer. That may seem sort of a ridiculous
comparison, but it is not. While soccer players may be atheist, Christian, Zen
Buddhist, NewAge Crystal Voodoo Necromancer, Tree Hugging NeoDriud, or followers
of Bob; the rules, officialdom, tenets and game of soccer says exactly nothing
regarding the presence, absence, traits or idiosyncrasies of a supernatural
being. It just plain does not concern itself with that premise.
That is precisely the same as for evolution.
Evolution neither requires nor desires spirits, sprites, spooks, spectres,
goblins, ghouls, ghosts or God(s). It says nothing, nothing, of the presence or
absence of (a) God(s); and by definition , it cannot. Evolution, as shown above,
is science. Science, by definition, is purely naturalistic. Therefore, the
"God Hypothesis" is untenable for use or consideration in evolution.
Succinctly put, evolution only concerns itself with the natural world; God(s)
and the like, are, by definition, supernatural and therefore not a
consideration, nor are they considered, when examining the natural world.
Evolution neither desires nor requires God(s); but
it does make them unnecessary. Sometimes the creationists drop their scientific
pretences and reveal their religious motivations by attacking evolution on the
grounds that it is an "anti-religious" or "atheistic" theory
(vide alta). The creationists would have one believe that evolution is
atheistic, because it contradicts their naively literal interpretation of the
Book of Genesis in the Bible. However, evolution is not necessarily atheistic.
Evolution is a scientific finding, and science tells us, by design and
definition, nothing about metaphysical (and oftimes silly) issues such as the
existence of God. We know through science that evolution is a reality. Whether a
God exists who used evolution to create life is an open question; although some,
like the author, find the entire question illogical and irrelevant.
Some claim that evolution is communistic, Marxist
or even anarchist. Using the method of dialectical materialism, Marx and Engels
were able to discover the laws that govern history and the development of
society in general. Using a similar method, Charles Darwin was able to uncover
the precepts of evolution of the biological world. "Darwin applied a
consistent philosophy of materialism to his interpretation of nature,"
states palaeontologist Stephen Jay Gould. "Matter is the ground of al l
existence; mind, spirit, and God as well, are just words that express the
wondrous results of neuronal complexity."
Even if, by similar methods, Marx/Engels and Darwin
devised revolutionary concepts; this in no way makes evolution and Marxism any
more related than the fish is to the squid I caught while fishing.
14. Is not evil,
Even if was, by any standard you desire, it would
not be a reason to assume it is wrong. Chemistry is responsible for millions of
deaths every year; physics, accelerating bodies to 9.78049 m/sec/sec, kills
those who believe gravity is not a fact; but we do not reject its findings
because of this. How people use a theory is not a judgement of its accuracy.
Fortunately we do not face this dilemma. Evolution
does not say what is right and what is wrong, but merely what has happened. A
strictly historical account of the Auto de fe or Crusades would not say that
they either were good or bad, rather, that they had happened (although it would
note their religious underpinnings). Similarly, evolution does not say that any
conclusions people might draw from it are good or bad. Evolution simply
"is".
15. is not mandated by law to be taught in US
public schools,
It is, and should, be taught in the science
classroom because it is science and science is what should be taught in science
class. As noted by the late Judge Overton in the 1980 Arkansas vs. McLean
"Balanced Treament" case; "science is what s cientists do",
and scientists 'do' evolution; not creationism. Never has it been legislated
that evolution must, by law, be taught in the science class, is simply was
because it is science.
It is wholly amusing (and somewhat aggrieving) to
witness the machinations of the so-called "Scientific" creationists,
who have been so enflamed in trying to achieve legislation for their battle-cry
of "balanced treatment". This whole issue is so riddled with oxymorons,
it's a lexicographer's delight. For instance, "scientific" creationism
is promoted by only a few fundamentalist Christian types with a heavy doctrinal
axe to grind and a thinly disguised, but ridiculously apparent, hidden agenda.
The Institute for Creation Research and the Center
for Creation Research are self-professed ministries; and for that, they make no
apologies nor have any qualms in accepting their tax-exempt status. They do no
research whatsoever (that is, their so-called 'research' consists almost solely
of their ransacking scientific publications for quotes from prominent
evolutionary scientists which could be lifted from their original context and
then perfidiously recontextualized in order to serve Creationist designs; they
also spend considerable 'research' time being an 'outreach' ministry, financing
expeditions to Turkey to ferret out gopher-wood ships and expend their remaining
time floating horsetails in aquaria; such is their 'research ' activities),
instead they content themselves with trying to 'disprove' evolution (about more
later).
They require the signing of a statement of beliefs
(all religious, all Biblical) in order to be counted with their little clan. Odd
that this is so diametrically opposite to what real science is and what real
scientists do. And yet these so-called, self-professed 'scientists' have the
unmitigated temerity to call mainstream scientists closed-minded. I personally
belong to 14 international geological, biological and paleontological scientific
societies and have yet to be required to sign a single document confirming that
I have a literal belief (or, for that matter, any beliefs) in anything.
Secondly, when one looks at the strategies of the
creationists; their deceptions, shoddy work, and illogic, their 'secret' agenda
becomes all too apparent. First they clamour for 'fairness' in balanced
treatment; that is, they want their narrowly-sectarian, fundamentalist,
Biblically-literalist religious dogma taught right alongside the science of
evolution in the science classroom. Well, besides being unconstitutional; it's
devious, disingenuous, and dastardly as well. If they truly wan t balanced
treatment, then they would be lobbying to present all the theories of
development of life on Earth.

Just when we're going to be able to fit all of this
into the science curricula and still get to any real science is, of course, a
yet to be addressed question; particularly by the creationists.
Secondly, when creationists try to procure
'balanced treatment', they often try and do this be attacking evolution; an
utterly fallacious endeavour (see #27: the False Dilemma [a.k.a., bifurcation
fallacy]). The status quo now, in the science classroom, is that evolution is
'in' and creationism is 'out'. What the creationists so desperately desire is to
overthrow that status quo and retread it to read: evolution 'in', creationism
'in'. But notice what a precedence this sets. The status of evolution remains
unchanged! In both cases, it is 'in'.
Now we can see just how truly unfounded and
fundamentally inane are creationist attacks on evolution. By their own
admission, in striving for balanced treatment, they are not trying to oust
evolution (balanced = equal for both); therefore anything that the creationists
have to offer must be defending or supporting creationism, on a scientific
(definitely not religious) basis; and not an attack on evolution (however
specious or irrelevant), for it's not the status of evolution that they're
trying to change, but rather the status of creationism.
20. is not dependent on the supernatural,
In fact, must exclude itself from this realm.
Evolution, as all science, must depend on exactly less than one miracle. No
God(s) required nor desired.
21. does not claim that "Man came from
apes",
Only misinformed types, typically with a
single-edged doctrinal axe to grind, maintain this. In fact, it is about as
matchless a "straw-man" argument as can be constructed. The facts of
the matter are that evolutionary theories maintain that humans and the great
apes share a common ancestor. Nowhere is the claim made that "man evolved
from apes"; and no evolutionary theorist makes such a claim.
This is due, in my opinion, to the abysmal lack of
scientific comprehension in the world today (fully 95% of Americans can be said
to be scientifically illiterate (American Scientist, Sept/Oct, p. 439-444 [1])),
the 'bad press' received by science in the media and the psuedoscientific pap
they present under the guise of science; the generally poor reputation of
science and scientists by non-scientists ("Science geeks", "math
is too hard," "Why the hell should I care that the Cambrian began 560
MYA? Will that earn me $ 150K a year?" and the like), deliberate
misinformation (finger pointed squarely at the so-called 'Scientific'
Creationists and their thinly disguised anti- and pseudoscientific agenda,
J'accuse!), and a failing of the scientific community in relating the incredible
vistas, amazing worlds (past and present) and life-enriching fulfillment of our
calling to those who are not scientists.
Although, in the final case there may be certain
reasons for scientists not wanting to discourse with non-scientists. For his
efforts in 'enlightening the masses', the late Carl Sagan of Cornell University
was branded the "evolutionary god-pa pa of science", "that
atheist Sagan" and "Sagan is probably a communist" by none other
than good old Henry Morris of the Institute of Creation Research. Similar
inanities and ad hominems are heaped upon Richard Dawkins, Stephen Jay Gould,
Stephen Haw king, and a host of other scientists who try and keep science in the
public eye. Can one scarcely blame science for refusing to cast "pearls
before swine"?
22. Evolution is not progress,
Organisms simply adapt to their current
surroundings and do not necessarily become "better" over time. A trait
or strategy that is successful at one time may be deleterious at another.
Studies in yeast have shown that "more evolved" strains of yeast can
be competitively inferior to "less evolved" strains. An organism's
success depends a great deal on the behaviour of its contemporaries; for most
traits or behaviours there is likely no optimal design or strategy, only
contingent ones.
23. has not, will not and cannot be proven,
There is a type of epistemological argument contra
evolution.
Science maintain that that nothing in science can
ever be "proven" and this includes evolution. Semantics aside,
"proof" and "proving" are not something done in science. As
the old saying goes: "Proof is for alcohol and mathematics"; natural
science deals not with proof, but rather evidence. This is another distinction
of science.
Continuing, the probability that evolution is the
correct explanation of life as we know it may approach 99.9999...9% but it will
never be 100%. Some would contend that this would lead to the conclusion that
evolution cannot be a fact (see #1). This kind of argument might be appropriate
in a philosophy class but it won't do in the real world. A "fact", as
Stephen J. Gould pointed out (see above), means something that is so highly
probable that it would be silly not to accept it. This point has also been made
by others who contest the nit-picking epistemologists.
"The
honest scientist, like the philosopher, will tell you that nothing whatever can
be or has been proved with fully 100% certainty, not even that you or I exist,
nor anyone except himself, since he might be dreaming the whole thing. Th us
there is no sharp line between speculation, hypothesis, theory, principle, and
fact, but only a difference along a sliding scale, in the degree of probability
of the idea. When we say a thing is a fact, then, we only mean that its
probability is an extremely high one: so high that we are not bothered by doubt
about it and are ready to act accordingly.
"Now in this use of the term fact, the only
proper one, evolution is a fact. For the evidence in favour of it is as
voluminous, diverse, and convincing as in the case of any other well established
fact of science concerning the existence of things that cannot be directly seen,
such as atoms, neutrons, or solar gravitation ....
"So enormous, ramifying, and consistent has
the evidence for evolution become that if anyone could now disprove it, I should
have my conception of the orderliness of the universe so shaken as to lead me to
doubt even my own existence. If you like, then, I will grant you that in an
absolute sense evolution is not a fact, or rather, that it is no more a fact
than that you are hearing or reading these words."
H. J. Muller, "One Hundred Years Without
Darwin Are Enough" School Science and Mathematics 59, 304-305. (1959)
24. Is not random nor relies on 'blind chance',
In all aspects of evolution, natural laws and
principles can explain what has occurred. These influences act as a controlling
force that guides evolution to predictable outcomes. Evolution (at the molecular
level) abides by the laws of chemical reactions (i.e., chemistry and physics)
which can produce complicated organic molecules naturally (we have witnessed
this in the laboratory). Organic evolution is directed by biological principles
such as natural selection and genetics, which again we have observed in the
laboratory. The odds are, at the moment of conception, over 70,000,000,000,000
(7.0x1013) to one that your genes will not come together in the combination now
in your body. However, you are here and it was all controlled by the principles
of genetics. Natural forces and laws govern and direct evolution, not
"blind chance."
25. does not violate the second law of
thermodynamics,
There has been much written regarding the old
canard that "evolution is impossible because it violates the second law of
thermodynamics". This is utter codswallop. Typically, if pressed, the
individual making such a claim will mutter something about "everything in
the universe tends toward chaos" and "you cannot derive order from
disorder". This evidences not a problem with evolution, but a deep lack of
understanding of basic science by the accuser.
Simply put, the second law of thermodynamics states
that in a closed system, "No process is possible in which the sole result
is the transfer of energy from a cooler to a hotter body." [Atkins, 1984,
"The Second Law", pg. 25]. Another way of stating this is that the
entropy of a closed system cannot decrease. Entropy is an indication of unusable
energy and frequently corresponds to intuitive notions of disorder or randomness
order of systems will not spontaneously increase. One may ask "What does
this have to do with evolution?", and well one might. Where it does is in
the creationist caricature of the 2nd law where they, in their sophomoric
simplicity, claim that evolution derives order from disorder; and that is in
violation of the 2nd law?
What creationists fail to note (whether out of
ignorance or duplicity, one cannot reliably say, although it's probably both) is
that the Earth and it's life are not a closed system. All they would need to do
is arise early some morning, and f ace due east. Do they see that large,
luminous ball of fusing hydrogen and helium hanging in the sky?
Creationists sometimes try to weasel around this by
claiming that the information carried by living things lets them create order.
However, not only is life irrelevant to the 2nd law, but order from disorder is
exceedingly common in nonliving system s, too. Snowflakes, sand dunes,
tornadoes, crystal growth, stalactites, graded river beds, and lightning are
just a few examples of order coming from disorder in nature; none require an
intelligent program to achieve that order. In any nontrivial system with energy
flowing through it, you are almost certain to find order arising somewhere in
the system. If order from disorder is supposed to violate the 2nd law of
thermodynamics, why is it ubiquitous in nature?
One final 'argument' creationists pose is that the
only true closed system is the Universe itself; therefore evolution, taking
place in that universe, violates the 2nd law. Well, for reasons stated above,
this is totally a fallacious claim. Regions of high energy flow can increase
order at the expense of apparent disorder. Further, the solar system (of which
the Earth-Sun portion thereof is which with what we are currently concerned) is
not immortal nor infinite. One day, our sun will consume most all of it's
nuclear fuel (in 5 or so billion years, so not to worry...yet), will go
"red giant" and consume Mercury, Venus and quite possibly the Earth.
If not consumed in this phase of stellar evolution, the Earth's oceans and
atmosphere will be boiled off into space and the Earth itself left a charred,
cold, very dead world. The bloated sun will consume the remainder of it's
nuclear fuel in a very profligate manner, spend itself and finally 'wink-out',
to become a dense, dead cinder in this region of space. Thermodynamics wins
again, and the entropy bill for the Sun-Earth system will be paid in full.
Now, can the creationists out there answer how
creation be valid when it violates the very 1st law of thermodynamics...where
matter can neither be created nor destroyed?
Remember: "God did
it." is not a valid hypothesis.
26. Does not deny (a) God(s),
There is no reason to "believe" that God
was not a guiding force behind evolution. While it does contradict some specific
interpretations of God, especially ones requiring a literal interpretation of
Genesis 1, few people have this narrow of a view of God.
There are many people who "believe" in
the existence of God and in evolution. Common descent could then describe the
process used by God.
But more fundamentally, it is fallacious to utilize
the terms "belief" and "believe" in natural science. Belief
requires faith. Faith is accepting that which is unevidenced or unevidencable,
typically without question. These concepts are totally alien and inimical to the
mode, methods and machinations of science and the scientific method. Certainly,
scientists may 'believe' and hold beliefs; but when they speak of them, in
whatever context, they are speaking of a personal prejudice (yes, remember that
they are also human; and therefore just as subject to human foibles as any
other); they are not speaking of science.
As far as science is concerned, it cares not one
whit what you believe, but cares infinitely more about what you think. Anyone
can have and hold beliefs; although it is vastly more difficult, but infinitely
more rewarding, to have thoughts.
27. And finally: Falsifying evolution does not
'prove' Creation.
This is known as the "False Dilemma";
inasmuch as that this argument (again, tremendously fallacious) claims that
there are only two possible explanations for a certain circumstance, in this
case the diversity of life on Earth; that is evolution or special creation. Some
maintain that if evolution is shown to be in error (this itself is an erroneous
supposition, for evolution is an observed fact; although theories of evolution
could be shown to be erroneous and therefore would require re-analysis and
possible abandonment of that particular theory of evolution, as was done with
Lamarkianism), that this would automatically prove creationism. I think that if
the gentle reader has slogged though all this thusfar, we need not once again
note the multiple errors of that conclusion.
It can be demonstrated that there could be another
possible explanation for the diversity of life on Earth, viz. for your reading
pleasure:
"THE LGM UNIDIRECTED PANSPERMIA, THE EARTH IS
JUST ONE BIG TEST-TUBE FOR EXTRATERRESTRIALS, MODEL".
You see, the "One, True" theory is this:
that the Earth over the span of geological time (beginning just about 3.75 BYOSA
[Billion Years Or So Ago]) was visited by a race of extremely patient
extraterrestrial genetic bioengineers from the Dinwoody Cluster in the galaxy of
Archeocetus.
Being relatively new to both space travel,
blackholes, warp drives, and recombinant DNA; they decided to start small...proteinoid
microspheres, protobioinformational macromolecules, paleoarcheviri...you know,
simple critters. Dump 'em in the ocean, give 'em a stir and stand back to watch.
Sort of a galactic sized ant-farm (of course, ants wouldn't show up until the
Cenozoic; they're a late model addition). Occasionally, back on Arglebargle 4
(their home base), an Arglebarglian equivalent of an Einstein would show up at
their tri-century geneticfests and show off his new invention.
The greatly revered Warroona (a state hero and
developer of in situ in vitro protoretroviri) came up with the idea of external
protection for creatures. This was too good to pass up. After all the diddling
around with multiple appendages, a stab at sexual reproduction (a fairly good
idea, as it turned out) and colonial critters; the Arglebarglians "Strangeloved"
the entire Earth (our naively so-called "extinctions") to pave the way
for Warroona's great next experiment.
It worked out great. Hoards of shelled, frustruled
and carapaced critters skittered about and littered the ocean floor. And in the
nutrient rich broth called 'seawater', they flourished. Unfortunately, the
Arglebarglians didn't account for plant life (seems that archealga were merely
an embarrassing by-product of one of their ships flushing out it's bilges before
a return trip home), and this stuff was taking over. So much, in fact, that it
changed the composition of the early atmosphere from reducing to oxidizing (by,
of all things, by-products from their metabolism) and now was thinking about
taking over the great unwashed plains that stuck nudely out of the oceans.
So, a pattern started to develop. Approximately
every 22.6 MY or so, some bright, young Arglebarglian bioengineer would come up
with some great, new innovation. Wanting to be first on the scene with such new
advances, the Arglebarglians would turn their "death ray" on the
Earth, and, again, "Strangelove" the planet. Although competent (and
terribly patient) bioengineers, they were not overly good mechanical engineers.
Their Strangelove ray would at times be set too
high (like the time 245 MYA, damn near took out everything), or too low (like
345 MYA, when the placoderms bought the proverbial ranch). But, it worked well
enough for their purposes (they themselves evolved a culture that existed only
for per diems, frequent flyer miles and a trophism for spaceport bars; but that
IS another story) and their experiments progressed nicely.
New, young, bright AG (hey, let's shorthand these
guys) bioengineers came up with the most improbable contrivances to give a whirl
on their test-tube planet. Amphibians ("Water: Don't leave home without
it.") to let animals conquer dry land (hey, the plants snuck out
first...those slimes), the amniote egg, and other such innovations.
Then things went into high gear. More and more AG's
were turning to Earth and it's growing ecology because it was (1.) a high
profile project, (2.) chock full of new critters to mess with and (3.) a great
way to milk research grants, expense-paid vacations, junkets with their comely
secretaries, and tenure out of universities.
So, all in all, the pace of innovation accelerated.
"Hey. Here's a trick we've never tried", remarked on particularly
bright AG bioengineer after a frat party, "Let's take one of those scale
covered, toothy characters and make 'em walk on [<hee, hee, get this>]
their hind legs..."
"Wow!", remarked his frat buddies in a
haze and din of alcoholic approval, "What a great idea."
Next came opposable digits, motile hands,
encephalization and, of course, a refined bipedal stance. No, we're not to ol'
Homo sap. yet. We're discussing archeosaurians here. Dinosaurs, gang. They beat
us humans to the advanced-trait punch by over 100 MY.
Things were going swimmingly for the AG's and their
experiments, particularly ichthyosaurs and mosasaurs...Fewer and fewer
Strangelove episodes were necessary as they were content to tinker and fiddle
with what was already available. Experiments included gigantothermy, facilitated
endothermy, opportunism, gigantism, dental differentiation; experimenta ad
infinitum. After a while, they noticed some smaller critters shivering in the
cool polar nights, what with their naked skin and all, so feathers were
developed as insulation. After yet another frat party, these feathers were
noticed to be good for snaring bugs (a mistake that the AG's never caught). They
also were aerodynamic. The bugs had flight, the pterosaurs (custom designed (by
committee) after an intense 12 kegger frat party) had flight; why not little,
feathered, flying dinosaurs?
All the while, one meek little AG bioengineer (who
was never invited to frat parties) was told to get after the Terran bug problem.
All of the frat guys were working on the high-profile (and typically large,
noisy and fierce) archosaurs. Being a mousy sort of person himself, he took a
totally different tack. He fashioned little, hyperactive bug-munchers.
They were small, though fairly buzzed on a terribly
high metabolic rate; fueled by, yep, you guessed it, insects. They had to be
insulated (again, naked skin was de rigeur for the AG engineers). Feathers were
already in use, so something new had to be used. Fur made it's first appearance.
With all the archosaurs stomping around, it's good
that the first mammals were small. They, by necessity, were also nocturnal, as
most larger archosaurian predators were diurnal. Accordingly, their senses
intensified and expanded, by necessity. Larger olfactory lobes, large eyes with
colour stereoscopic binocular vision, hand [paw]/eye co-ordination, etc.
All was moving right along for the AG engineers.
Oh, sure, there was the occasional cosmic conflicts; but comets, asteroids and
the like plopped onto the Earth so infrequently that they weren't paid much
mind. Besides, with _Utahraptor_, _Tarbosaurs_ and _Carnotaurus_ to play with,
why worry about dirty cosmic ice-balls and hunks of rather unremarkable rock
tumbling around the solar system?
After the "Big One" of 65 MYA, the
Arglebargian bioengineers were most distraught. They were having trouble with
their dinosaurian clans already, and the whole of the biosystem of the Earth was
out of whack. Mountains were rising, epeiric seas draining, temperature cooling
globally, then the "Big One". Killed every blessed <wink>
creature over 25 kg in mass. That did not leave the AG's much to work with.
They tried an early dalliance with birds. Huge
flightless carnivorous ratites were given the go ahead. After only a few million
years (due to the K/T debacle being still fresh in the powers-that-be's minds),
the program was scrapped. What was left to work with? "Well, there are the
furballs", remarked one A G engineer, again one never invited to frat
parties.
Grudgingly, the elders consented and soon grant
proposals and all sorts of experiments were funded.
Hooves, claws, extensible tongues, protrusible
lips, prehensile tails... all given the green light.
After myriad mammals marched across the face of the
Earth, the elders again grew restive. "*YAWN*", commented one elder,
secretly yearning for the good, old days. "Remember the Late Cretaceous?
Now *THERE* was a time!". Hearing this was an upstart AG bioengineer who
was also keen on ancient history books. "Late Cretaceous "eh? What was
so special about that time and those critters...?"
His proposal for mammalian bipedalism, opposable
digits, and increased encephalization was greeted with mixed results.
"Nahhh. We tried that once. Worked great, but
remember what happened?"
"But this time is different!", protested
the engineer. "These critters are already insulated, have a lower species
and generic diversity and live in protected environments...[turning to an
aid...what's that called again? Oh, yes...], in forests."
"Nahhh...once burnt, twice learnt. I know,
let's make something new. With...pouches...webbed feet...poison glands!"
exclaimed the elder after a 6 martini lunch.
In the end, both projects were funded, but as pilot
projects. One on an island continent, the other on a larger continent next-door.
Here, the AG's screwed up, for the first project had been started on the sly
millions of years earlier over in the old Gondwana continents. But even the AG's
were surprised by the rapid takeoff of the African project.
But, by this time, after all the 6 martini lunches
and herds of tenured professors roaming the steppes of their home planet, the AG
were in a bit of their own fix. Things at home were getting very messy indeed
and a bit of housecleaning was in order. They weren't able to check their
charges for a couple of million years.
When they finally returned, and saw what had
happened to their project planet, they blanched. Never before had they seen a
species spread like such wildfire over the face of a planet. In every niche,
cranny, and environment. And, they had developed technology, science and
civilization.
Unfortunately, they had their scopes set upon the
noisome twee little burg of El Cajon, Ca., upon an even more noisome group
called the "Institute for Creation Research". Investigating deeper,
they noted there the worship of an ancient tome of Middle Eastern mythology, a
total disdain for logic and reason, a penchant for out of context quoting,
deliberate misrepresentations and out-and-out lies; all in the name of some
"omnipresent", but strangely absent, deity.
After seeing all this, the AG's decided to give up
6 martini lunches, mothball the current project and return to Arglebargle to see
if they could milk grants out of the system on another, perhaps more promising,
planet. One not quite so far out i n the backwaters of some distant, and rather
prosaic, galaxy...far, far away...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Well, there you have it. The LGM theory. Neither
evolution nor creation, but consistent with the fossil record and entirely
plausible.
Unfortunately, it is not testable, falsifiable nor
predictive. These are the attributes it shares with creationism.
It does though contain exactly <1 miracle and
<1 deity, attributes it does not share with creationism.
And thus endeth the lesson.
