The most confusing aspect of the study of evolution is the nature of the first
step, natural selection. Here the debate rages at its loudest. Yet the very proposition of
natural selection would seem implausible. We can hardly suspect, early in school, as we
embark on complex study, that it is the first step that might be wrong, or at least,
not established, nor recover clarity if we take this as an established foundation. Robert
Reid notes in Evolutionary Theory, The Unfinished Synthesis, "I thought my
failure to understand selection theory fully was the result of the specialization of the
subject beyond my simple comprehension. Confident that every aspect of natural selection
was for the best, I little knew that it had long been criticized for just that Panglossian
felicity".
- Huxley on Natural
Selection The history of the development of evolutionary
theory is complex and often confusing. We associate more than any other
T.H. Huxley with the triumph of Darwinism, yet might forget that his
views were complex:
"Huxley's views about evolution 'evolved' over time. Initially a
saltationist, he eventually adopted Darwin's gradualist position. In
time, he also accepted the doctrine of progressive development after
arguing against it for many years. However, he remained skeptical his
entire life of the power of natural selection to create new species.
What were his reasons, and can he still be called a Darwinian in spite
of his reservations concerning the most basic tenet of Darwin's
theory? In Huxley's famous Times review of the Origin, he
stated that while Darwin's theory explained a great deal about the
natural world, he personally preferred to adopt Goethe's aphorism
"Thatige Skepsis," or active doubt. He did not deny that
natural selection existed in nature, but could it account for all the
effects that Darwin ascribed to it?" Thomas Henry Huxley,
Sherrie Lyons, p. 231
Some familiarity, that's all, with
the critiques of natural selection are necessary for our study of history.
There natural selection suddenly becomes a problem. So how did this problem
arise, if natural selection accounts for everything?
This is a speed readers approach to
being a Darwin critic. There is no other way. If you are a one book Darwin
groupie, you will be brainwashed. If we produce a critique, read it. No
excuses. We are not dogmatic. I cannot refute Darwinist assertions, e.g. that
language arises via natural selection. But such thinking could never be
dogmatic, yet currently is, what a scandal. Just be aware of the tremendous
underground literature.
We do not propose here the design
argument as a substitute for natural selection, although this legacy must be
considered. The Trojan horse for God has humor, but it tends feed Darwinism
rather than refute it. For evolutionary naturalism, which doesn't imply
natural selection exclusively, however primitive as yet, seems the highest
likelihood The Darwin debate is a two-edged sword. One side gains the upper
hand, then the other makes a comeback, then it all goes in reverse gear, an
infinite loop. Although one can be critical of Dawkins, The Blind
Watchmaker, the equal and opposite atheist agenda to the theist agenda
requires careful consideration, and exploration. To be an 'atheist' should
mean, not just debunking Christian dogma, but encountering, as did
Nietzsche, the 'Zoroastrian dialectic' of good and evil. Don't fall for
sweet divinities doing punctuated equilibrium, please. It is not a funny
subject. For injecting divinities into evolutionary thinking is
part of what drives Darwinism further into its rut. There could be a 'blind
watchmaker' that was a watchmaker, but blind, watch out for the trap in
Dawkins' provocative thinking. Homer was blind, but produced a complete
epic, so...? The problem with Dawkins is that we think he succeeded, when
what he does is produce a powerful dialectic. This dialectic devours its
children. Also, genetic fundamentalism, as in The Selfish Gene is an
inherently limited line of argument, as the world of the genome surely now
suggests.
So, study the history and
literature of the argument. Most of the early critics summarized the
problems, as with Mivart. Michael Denton's Evolution, A Theory
Crisis is a classic critique here, no matter that it has been lambasted
many times. Several good texts for anyone suspecting a problem with
Darwinism are
Darwinism, Refutation of a
Myth, Soren Lovtrup; Evolutionary Theory, The
Unfinished Synthesis, Robert Reid,
Beyond Natural Selection,
Robert Wesson
In Beyond Natural
Selection, Robert Wesson gives a naturalist's second opinion of the
gritty details that mount up and cast a shadow on the Neo-Darwinian
synthesis, noting, p. xii: "Natural selection is credited with seemingly
miraculous feats because we want an answer and have no other. There
probably cannot be another general answer. Biologists, it seems, must do
without a comprehensive theory of evolution." To question natural
selection does not disprove it. If we doubt it, we can be forced to
think creatively for the first time, for it remains to be elucidated. To
question it requires engaging its study, thus we lose nothing. Wesson
summons up an impressive list of oddities that current theories simply
disregard. Simple things, like the absence of selective advantage in
dreaming, the failure of sexual selection in practice to feedforward
intelligence, the six-leggedness of insects, the archaeopteryx, etc,
etc,... Looking at a DNA molecule should make anyone fainthearted. Could
any random change in such a fantastic labyrinth occur at all in an
evolutionary sense now considered?
"Many very simple facts, such as that all the
millions of species of insects, and no species of non-insects have six
legs, might well might well be considered to disprove natural selection
as a generalization." Robert Wesson, Beyond
Natural Selection
Natural selection is surely no more visible than
the deity. And it is also relevant to ask not merely whether natural selection
has been proved, but whether it can be proved. Evolutionists are fond of
taunting the creationists that their miracles of special creation can, by
definition, be neither proved nor disproved. Yet we frequently find
evolutionists arriving at propositions that are in the same category. The Bone Peddlers,
William Fix
Some obviously feared that if natural selection
were discarded evolution would be endangered. They thought the two theories
inseparable and foresaw a rebirth of superstition. But dropping natural
selection leaves the evidence for evolution untouched. It was not even a
question of dropping natural selection, for natural selection is an observed
fact. It was a question of seeing--as Darwin came to see--that selection occurs
after the useful change has come into being... Jacques Barzun, Darwin, Marx, Freud
L. Spetner in Not By Chance explores the
clear evidence for non-random variation, noting that Darwin himself saw
the problem finally with his original thesis.
An extensive history and
bibliography is Origin of the Species Revisited, by W.R.
Bird.
Now the new world of 'complexity theories' bids to bridge the gap and
answer to both poles, thus, S. Kauffman, in At Home in the
Universe:
- Since Darwin, we turn to a
single, singular force, Natural Selection, which we might well
capitalize as though it were the new deity. Random variation,
selection-sifting. Without it, we reason, there would be nothing but
incoherent disorder. I shall argue in this book that this idea is
wrong. For, as we shall see, the emerging sciences of complexity begin
to suggest that the order is not all accidental, that vast veins of
spontaneous order lie at hand. Laws of complexity spontaneously
generate much of the order of the natural world. It is only then that
selection comes into play, further molding and refining. P.
8
Evolution From Space by Hoyle and
Wickramasinghe, is another classic, with an series of distractions near
its main statistical critique, which is the most refuted of unrefuted
arguments ever penned.
Kevin Kelley, in Out of Control,
speaks of 'Postdarwinism' and provides some good insights into the
limitations of the current paradigm, plus bibliography.
Issues of
the statistical implausibility of random changes in coding sequences of
DNA are, and remain, a powerful challenge to the current picture, which
has, however, tacitly acknowledged this as it moves on to explications
of body plans, evolutionary toolkits, hox genes, and morphogenesis.
Some writers on evolution,
acknowledging implicitly the problems of natural selection of coding
sequences, tend to suggest that mutations in regulatory processes are
the answer. But here again, we must suppose, the problem re-arises all
over again. Cf. the objection of Senapathy in Independent Birth of
Organisms, p. 138, "Regulatory sequence mutations also can only
bring about variants of the same gene or can only lead to defective (or
incorrect) expression of a given gene, not to new genes or to a new
developmental pathway."
In Sudden
Origins, J. Schwartz looks at the important, rarely told, history
of the shifting debate over punctuated versus continuous versions of
evolutionism in relation to population genetics, and brings in the new
research on 'homeobox' genes. Commenting on an attempt to simulate
models of the evolution of the eye, "Do we actually need to invoke such
an elaborate thought experiment in order to understand the origin of the
vertebrate eye, or any eye, for that matter? I think not. And the
reasons lie in knowing that there are homeobox genes for eye formation
and that when one of them, the Rx gene in particular, is activated in
the right place and at the right time, an individual has an eye. When
something goes awry with this gene, the other homeobox genes involved in
eye development cannot do their job, and an eye does not form. Clearly,
the difference between having or not having an eye is a different
proposition altogether from the gradual accretion of the bits and pieces
that make up an eye. At the genetic level, major morphological novelty
can indeed be accomplished in the twinkling of an eye. All that is
necessary is that homeobox genes are either turned on or they are not.
(p. 362)
Random
Variation versus Random Evolution Darwinian theory speaks of 'non-random' natural selection with
random variation and thus selection defeats randomness, True. But don't be confused by that distinction.
In the large, we should expect a continuous pattern of evolution, when
we find instead evidence of some additional factor. But any change in
the meaning of the word 'selection' will not fall in the range of our
critique. Thus an active selective process by any method, is something
different, consider a work like Eigen's Steps to Life. Such works fall
out of the range of this basic criticism. Let us note that Darwin himself ended up unsure on this
point. Random evolution is one thing and
natural selection of random variation may be non-random by a
technicality, but the basic point is clear. Something is missing in the
standard account. Here 'nonrandomness' in our sense means the there is some irregular pattern in the expected continuity
suggested by selectionist evolution. Consider children in a school yard.
The schedule says, go outside and play at ten o'clock. This makes the
'random play' of unsupervised children inside the selected area of play
random within the non-random schedule, not all day long. Thus the
evolutionary record should be uniform
continuity, else there is another factor. If there is a rustling
in the bushes, you suspect a cause, etc... A further twist can be seen in the claims for the
contingent, e.g. a meteor impact and the fossil record of the dinosaurs.
But this is not the same as a cause of evolution, in all senses. Thus, and this is
confusing, a contingent or random (we presume) meteor impact derandomizes the fossil
record. Beware of the hopeless confusion of terms. These accounts are
all especially confusing. The nonrandom factor in general is simply evidence
of an unknown evolutionary incident, process, or function. It is because
religionists always attempt to say this is a sign of a supernatural
cause that Darwinists retreat into oversimplification. Then again, some uses are
inserting a force into the concept of selectionism, 'selection pressure', the 'force' of
selection, etc.. There are no such forces, by definition. If there are,
then Bergson deserves rehabilitation. There probably are! But they are
not likely to be 'forces' in the physics sense. It's all a muddle.
If we knew of one, or discovered
one, then selectionism should be set aside as a secondary process. Thus, such language is tantamount to a
confession selectionism fails.
Macroevolution and Punctuated
Equilibrium The basic argument against natural selection is
also one against 'slow evolution' and 'continuity'. Further, these
questions have ideological overtones. But the basic issue is that
natural selection suggests evolutionary continuity, and the record does
not show this. If we can evade the distraction of supernaturalism
claiming this fact, we are left with something simple, about which we
know little. Confusion reigns, for the next series of traps are anything
from vitalism to Bergsonian evolutionism, to what not. That is, these
gaps, rate changes, and discontinuities are high level 'perceptions'
lacking sufficient data of evolution in action, by mechanisms we do not
know, because we do not see them. It is not safe to speculate. But
with history we need not speculate. We can see a remarkable example of
'punctuated equilibrium' behind this history. The problem is that the
term 'punctuated equilibrium' is not defined properly, and only
describes a pattern, not a process. The term might collate many
different processes, from the comet impact that produces dinosaur
extinction, to climatic factors that accelerate natural selection, to
anything else. Thus the use of the term is too muddled for consistent
use. However, we will suggest once the relation to history, using
quotation marks:
The eonic effect as
'punctuated equilibrium' (?) Watch out!
The spectacle of world history
shows a remarkable example of 'punctuated equilibrium' in the sense of
rapid cultural evolution and intermediate periods of 'stasis'. Don't mix
this term with the study of history unless you wish a host of useless
arguments. The situation proposed by Gould and Eldredge is quite
different, and they invented the term.
But the constrast of fast
evolution and stasis is a mysterious component of the eonic
effect. And this
is very close at home indeed, as we look at the non-random pattern
clearly visible in world history. The term 'punctuated equilibrium' can be used once to suggest a
different insight to those who are confused about the nature of
macroevolution, and then dropped, for we must adopt a new terminology
applied to historical subjects.
Development and Evolution
From Cells, Embryos, and Evolution, J. Gerhart and
M. Kirschner, Blackwell, 1997, paperback. Refer also to H. Keller's The
Century of the Gene, for some background.
For the most part evolutionary biologists have relied on theories of
selection and population genetics as explanations for evolutionary change.
But looking at selection as the cause of evolutionary diversification has
some pitfalls. Form is so tied to function that many biologists have been
tempted to interpret every feature of an animal as serving some selected
purpose. That this temptation exists is sufficient to indicate that there
are few frivolous or neutral qualities to life compared with the number of
adaptive ones. However, selection only provides a filter on the possible
forms. It screens the forms presented to it by development and the
activities of cell biology. It is the processes of embryonic development
that are responsible for all of the morphological details, and selection
only affects those that significantly influence fitness. ... The search for
for a biochemical basis for diversification that is selected upon during
evolution has recently led to a paradox: whe re we most expect to find
variation, we find conservation, a lack of change....p. 1
And in conclusion: p. 587
Has Evolvability evolved and if so, is it the result of clade selection?
Two of the most serious and novel questions raised by our consideration of
the flexibility and robustness of cell biological and developmental processes
are"
1. Is the capacity to evolve a selected trait in organisms, and
2. Has this trait itself evolved under selection?....
Micromutations do occur, but the theory that these alone can
account for evolutionary change is either falsified, or else it is an
unfalsifiable, hence metaphysical, theory.
I suppose that nobody will deny that it is a great misfortune if an entire
branch of science becomes addicted to a false theory. But this is what has
happened in biology: for a long time now people discuss evolutionary problems in
a peculiar 'Darwinian' vocabulary--'adaptation', 'selection pressure', 'natural
selection', etc,--thereby believing that they contribute to the explanation
of natural events. They do not, and the sooner this is discovered, the sooner we
shall be able to make real progress in our understanding of evolution.
I believe that one day the Darwinian myth will be ranked the greatest deceit in
the history of science. When this happens many people will pose the question:
How did this ever happen?..."
Soren Lovtrup, Darwinism: Refutation of a Myth, p. 422
The study of history
requires seeing the dangers of selectionist thinking. To assume natural
selection produces all evolution is a recipe for disaster, we should demand
the highest standards of proof, instead.... WHOA! Runaway theory. No amount
of debate, it seems, will talk Darwinists out of the preconceived notions
here. They are simply stone cold and out of it. In part, this is justified
by the fact that the counterclaims also tend to fail. It is essential
for one's own understanding to cross this bridge, otherwise nothing will
make sense in evolution. Natural selection is like an aggressively
defended bluff, all too conveniently beyond disproof. And there can be no
doubt that this is one component of evolutionary processes. But its agency
as the sole factor in the progression of major forms is surely open to
question. In many ways the traditional critics have won the debate, please
note, for we see that developmental processes are involved in many of the
biological structures once thought to The basic body plans of animals, for
instance, have remained unchanged since the Cambrian. Most, of course, associate challenges to Darwinism with
religious or Creationist views, but such an exclusive association is a false one. The
mathematician Johann Von Neuman was skeptical, and many mathematicians have always been
wary of the statistics of selection. In any case, theories of evolution are on the
move again after a long period of rigidity.
Descent of Man
Paul Davies, Are We Alone? Basic Books 1995, considers the issues explicitly, and notes, page 86
One of the oddities of human intelligence is that its level of advancement seems like a case of overkill. While a modicum of intelligence does have good survival value, it is far from clear how such qualities as the ability to do advanced mathematics, create complex music or develop rich language structures ever evolved by natural selection...This raises the interesting question of when these abilities were selected for. Most biologists believe that the structure of the human brain has changed little over tens of thousands of years, which suggest that higher mental functions were selected long ago and have lain largely dormant until recently. Yet if these functions were not explicitly manifested at the time they were selected, why were they selected? How can natural selection operate on a hidden ability? ...The case of the Australian aborigines is intriguing. These people remained almost completely isolated from the rest of the world for 40,000 years until the arrival of the Europeans. Yet they are today essentially indistinguishable from Europeans in their artistic, linguistic and musical abilities and, when educated, in their mathematical ability too. This suggests that either the
'maths' gene and others were selected for more than 40,000 years ago, and have remained hidden and 'unexpressed' for countless generations, or that these higher abilities have developed in parallel with the rest of humanity as a bizarre form of biological convergence with no apparent use. Either way, there is a mystery as far as orthodox Darwinism is concerned. p. 86
Arthur Koestler,
Janus, Hutchinson, 1978
Arthur Koestler's views on evolution have always been a reminder of how many
dissenters on evolution have never reached print, if a well-known author
automatically gets work on such a controversial issue published.
The funny charm of Janus, with its remarks on Wallace and the brain, and the
tale of Ali, can help to make one simply snap out of the Darwin
mesmerization syndrome, to which debate and rational discourse rarely
contribute anything. It is a question of assuming you already know, have the
endorsement of rocket scientists, that this position is sophisticated
science, in a word, a hopeless condition too far gone for anything but a
loud sound, a sound beating, or some extraordinary jolt to consciousness.
...in creating the human brain, evolution has wildly overshot the mark.
An instrument has been developed in advance of the needs of its
possessor...Natural selection could only have endowed the savage with a
brain a little superior to that of the ape, whereas he possesses one very
little inferior to that of the average member of our learned societies....
This was written by no less an authority than Alfred Russell Wallace, who
co-fathered with Darwin the theory of evolution by natural selection. Darwin
instantly realized the potentially disastrous implications of the argument,
and wrote to Wallace. 'I hope you have not murdered completely your own and
my child.' But he had no satisfactory answer to Wallace's criticism, and his
disciples swept it under the carpet.
Why was that criticism so important? There were two reasons. The first is
merely of historical interest, in that Wallace's objection demolishes one of
the cornerstones of the Darwinian edifice. Evolution in Darwinian and
neo-Darwinian theory must proceed in a very small steps, each of which
confers some minimal selective advantage on the mutated organism-otherwise
the whole conception makes no sense, as Darwin himself kept reiterating. But
the rapid evolution of the human cerebrum, which some anthropologists have
compared to a 'turmorous overgrowth', could by no stretch of the imagination
be fitted into this theory. Hence Darwin's agonized response, and the
subsequent conspiracy of silence.
The second, and by far the more important, aspect of Wallace's criticism, he
himself does not seem to have fully realized. He emphasized that the
'instrument'-the human brain-had been 'developed in advance of the needs of
its possessor'. But the evolution of the human brain not only overshot the
needs of prehistoric man, it is also the only example of evolution providing
a species with an organ which it does not know how to use; a luxury organ,
which will take its owner thousands of years to learn to put to proper
use--if he ever does.
The archaeological evidence indicates that the earliest representative of
homo sapiens--Cro-Magnon man who enters the scene a hundred thousand years
ago or earlier--was already endowed with a brain which in size and shape is
indistinguishable from ours. But, however paradoxical it sounds, he hardly
made any use of that luxury organ. He remained an illiterate cave-dweller
and, for millennium after millennium, went on manufacturing spears, bows and
arrows of the same primitive type, while the organ which was to take man to
the moon was already there, ready for use, inside his skull. Thus the
evolution of the brain overshot the mark by a time factor of astronomical
magnitude. This paradox is not easy to grasp.
Arthur Koestler, Janus, 1978, p. 274
New ideas on Descent of Man *
The Monkey in the Mirror : Essays on the Science of What Makes Us Human
by Ian Tattersall
It is one of the mysteries of the twentieth century that everyone thought
they had a theory of evolution accounting for the descent of man, when in
fact they didn't. And too many books on human evolution, attempting to fit a
square peg into a round hole, start to beat around the bush and are are so
confusing due to dogmatic reiterations of received theory you feel you have
been had, if you can finish them. This short book of essays is an exception
and cuts to the quick of the issues, and is really a 'must-read' for getting
your bearings in this field, once ridiculed by a book called Bone Peddlers
by William Fix. First, it makes clear how little we know about human
evolution, in the paucity of fossils from which our understanding comes.
That is essential, for we imagine that we are required to take on faith
everything asserted in this field, when in fact, it is almost void of
certainties. Next, it intelligently graduates from the disorderly punctuated
equilibrium debate, in its several innings, to avail itself of new insights
and proposals of the last generation, among them the idea of 'exaptation',
non-adaptive innovations waiting on their realized use in a later context.
The work of J. Schwarz in Sudden Origins with its considerations of
developmental genes and the spread of recessive mutations comes to the aid
of the overall perspective, whose novelty, correct or not, as a new form of
evolutionary explanation is refreshing and intriguing. Rejecting the idea of
natural selection as a creative force fine-tuning adaptations and
distinguishing morphological change from speciation, the work proceeds
briskly through the hominid sequence with a clarity not seen in most other
works in this area, and makes clear the difference between anatomically
modern and behaviorally modern man, and all this in relation to the issue of
the Neanderthals. There is still, in this reviewer's opinion, a void in the
whole account, centering on the issues of consciousness and language, indeed
Tattersall makes this clear, but at least the overall sequence begins to
make sense with this ingenious new means to reconcile fast evolution and
slow evolution, speciation, and much else. Although short, and at first
apparently lightweight, this turned out to be one of the most useful books
on human evolution I have read. I recommend not letting Darwinian arm
twisters deflect your attention from some basic issues here.
cf. also, The Myths of Human Evolution, by Niles
Eldredge, and Ian Tattersall
The stance of the Exobiologist
One could
way to bypass both Darwin dogma and the problems of controversy in being
a Darwin critic is to adopt the perspective of exobiology, just before
the point of adopting any particular viewpoint in this field. The
exobiologist stands back, and asks, what is the place of life in the
universe? Does it arise at random, is it universal or confined to a
contingent sequence on earth, and so on. This stance implicitly provokes
all the mischief of the Darwin critic with none of the hastles with
Darwin fanatics. A good start, Here Be Dragons, by D. Koerner and S.
Levay. Cf. also, Paul Davies, Are We Alone?
The reason we distance ourselves from the design argument
is that our operating hypothesis is that natural selection is an incomplete
explanation, but that there are possibilities for naturalistic explanation
that are not exhausted by empirical research. The criticism that this
'naturalism' might be a philosophic stance or bias must be considered. But
much of the criticism is also biased. But the facts tend
strongly toward evolution, reconceived in a broader sense. The fossil record
makes no sense without the idea of evolution, and still makes no sense with
the idea of natural selection. The sociobiological claims that ethical
behavior arises from natural selection, and the various hypotheses of kin
selection and group selection are simply ad hoc extensions to Darwin's
thesis, and are not very convincing, and stand or fall with the prior
assumptions about the universal application of natural selection. Thus the
meaning of evolution remains up in the air, the reason for the endless
debate, as rival parties attempt to exclude the middle ground, or make
theism or atheism a derivative metaphysical conclusion. .
Evolution, History of an Idea
The history of the idea of evolution, and the
evolution of evolution, is a complex one, often confusing correct study. The
idea is clearly born in antiquity, as with so much else, in tune
with the rise of Ionian Enlightenment. Reemerging in modern times, during
the Enlightenment, we find early ideas of cosmic evolution in the
philosopher Kant, whose stance, along with that of Hume's, is and remains of
significant interest as the question of directionality and 'evolutionary
causality' remains forever up in the air. For the dilemmas of
rationalism and empiricism that he addressed resurface in disguise in the
great debate ignited by Darwin's theory. Kant's views on the argument by
design were far more sophisticated than what came later, either from
traditionalists or Darwinists. In many ways, in the endless confusion over
the fact and the theory, Lamarck is the first major theorist of evolution,
with the popularization of the idea occurring in the remarkable episode of
Chambers' Vestiges, which paved the way for Darwin's success. The
exclusive emphasis on Darwin's publication of his Origin forgets that
long gestation of the idea
-
Evolution, The History of an Idea, Peter
J. Bowler: "We can no longer believe that the [theory] simply
rolled back all opposition by virtue of its demonstrable technical
advantages. On the contrary, Darwinism flourished despite a number of
crucial objections that were to give a great deal of trouble later on,
until resolved by the synthesis with Mendelian genetics. "p. 23.
The great success of Darwin was followed by the near eclipse of the
theory toward the end of the nineteenth century, when the work of Mendel
was rediscovered. For a theoretical account of the rise of the
Synthesis, cf. Sudden Origins, by Jeffrey Schwarz, along with
Bowler's The Eclipse of Darwinism.
-
For a dissenting view of the history of evolution just
before Darwin, cf. Soren Lovtrup's Darwinism: Refutation of a Myth,
with its account in light of the four theories of
evolution Currently resurfacing in the age of the genome
is the significance of the early developmental tradition. As Lovtrup
notes, the early so-called 'transcendentalists', such as the two Saint-Hilaire's,
von Baer, Owen, Chambers, were really what he calls 'macromutationists'
with their insights into embryology and development. It is significant
that Huxley was greatly influenced by this side tradition.
Complexities...and Complex Systems: Dynamics on the
Move
Because of the legacy of
Newtonian physics, and the educational lag in absorbing new advances, we see the
'unconscious' implications of causal modeling haunting the spread of fundamental science
into the social and biological sciences. And yet we have no grounds for assuming such
models could really work. Many of the problems of the social sciences spring from the
difficulty of correctly understanding or keeping up with physics and the real nature of
reductionism and its implications. Even before the world could digest Newton, the field of
mathematics and dynamics was moving on. One could even argue that 'Quantum Mechanics' was
born at the end of the eighteenth century in the formalism of Langrangian and Hamiltonian
mechanics, as Newtonian social science was getting underway. And the existence of a whole
new dimension behind mechanics was spotted by Poincare at the end of the last century.
This has now produced the fascinating new world of Chaos, and the various efforts, not
quite successful, to extend the range of the old types of theories into new realms. But
even if we find this new form of mathematics unable to account for the realities of
evolutionary systems, its extension of thought automatically opens the window for some
fresh air. The lesson of previous scientific triumphs now appearing stale in their range
of false applications should induce a more seasoned perspective on the natural account by
scientific means. In any case, the eonic effect shows many distant cousin similarities to
this type of dynamics, once we isolated psychology from sociology, man from the vehicle of
social evolution. The world or research is now tackling the new 'science of complexity'.
Man's history shows plenty of complexity, but also a strange simplicity.
But the complexity is tremendous.
A revealing thing happens as we bring evolution home to human history, the number of
topics, sub-theories, descriptive corners, theoretical preliminaries starts to take off
stratospherically, and it becomes difficult to state exactly what phenomenon is to be
explained! Complex indeed. And we must struggle with our historical resolving power. What
really happened in the period -900 to -600 in ancient Greece, or Israel? We at least have
some information. What happened to man in the period -50000 to -25000? We don't have any
information. Yet we are certain how man evolved in the periods about which we have no
information, but suddenly unsure about the periods where we have some. There are simply no
simple explanations of such complex developmental processes. We are always closing on
a more detailed record of the facts. It is confounded by our means of observation, our
historical resolving power.
But we may get lucky: can nature
handle such complexity? Or will it start to break up into strange 'evolutionary patches'
defeating the intractable nature of the whole. We see a curious simplification of this
kind in the eonic effect. We can chase nature, for a brief five thousand year glimpse.
A theory tends to be
defined (at its most restrictive) as a predictive model about a phenomenon. Or else a 'how
it works', at a minimum. With the eonic effect we can see no theory in this sense is
possible, even though the apparent antithesis is also false, that there is no action of
evolution except free activity. We see a law that is no law. For we indirectly see
mechanism, but are granted no predictive resolution. And this mechanism, as we close in,
simply disappears and leaves no traces. At high zoom levels, we can infer its existence.
At deeper zoom levels, it disappears. That is a strong indication we are inside
'evolution'. We could never in practice detect its mechanism (perhaps). Instead of
'still another theory', we can assess the scale and terms required for any such theory,
and they are tremendous.
It is also true that what we will
call 'the eonic evolution of civilization' might have nothing to do with the organismic
evolution of primordial populations. We can argue that there is probably a very close
connection, a master clue. But, one way or the other, we don't even need the term
'evolution' to study the eonic effect. Nevertheless cultural evolution is not a matter of
cultural selection, cultural competition, value-free historical laws, or economic market
emergence. It isn't any of those things. It is important to be clear that this 'eonic
evolution of civilization' precludes pretty much any implications Darwinism applied
to human cultures. The sociobiological claims are simply confusing the issues, thus the
claim that religion is a form of evolutionary adaptation dies hard, and in fact doesn't
die at all. It is hard to deal with reasoning that assumes altruism must be explainable by
selectionist arguments, since natural selection must be true. Maybe the whole theory is
disproven just there. The dangerous fallacy of 'cultural selectionism' mixed with
economism has passed into currency and been granted a license it does not deserve, and one
whose effect on society cannot go unchallenged. Study of the eonic effect is useful
because it demands everything all at once, and shows the strong suggestion of a large
scale evolutionary process in just what we might have deduced by hindsight, one that is
however a conjunction of both historical mechanics and value
emergentism.
A-Life:
Although the claims for
artificial evolution seem exaggerated if they are pressed into service as substitutes for
Darwinism, the interest in the subject is great, for we do indeed get a glimpse of new
possibilities of theoretical explanation beyond what we could have imagined. Cf.
Steven Levy's Artificial Life, and Kevin Kelly's Out of Control. Claus
Emmeche, The Garden in the Machine (Princeton, 1994).
Thermodynamics &
Self-organization
Theories of evolution are
confusing because they leapfrog thermodynamics, or wish to but fail, and we can look back
on Darwin's reaction to Kelvin's criticism of his theory with some wariness. This was the
issue of the significance of thermodynamics to the time-scales needed for evolution. We
might indulge in another heresy here by suggesting that Darwin and Kelvin were both
'right' for the wrong reasons. Kelvin was oddly out of sorts about Darwin, became dogmatic
and is given short shrift now, but surely his wrong view, with some bias against
Darwinism, was still a fresh impression and his point was simply to see a
catch, the dilemma of statistics in the selectionist thesis, while Darwin could see that
'evolution' was a fact irregardless of objections of the physicists. The subtle fallacy in
the debate over the Second Law is now seen to revolve around the dangers of applying the
law to systems that are not closed. We cannot simply apply it to the whole universe. We
see clearly that self-organization is a fact. The problem with Darwin's view was his
confusion (and ours) over the shadow meanings of 'natural selection', stretching from
passive process to active ordering force. Note the cryptic appearance unmentioned in
semantic terms of the sasquatch 'force'. Kelvin's real intent would be to have considered
that randomness degrades order, and that some active creation of order is needed to
account for life. Thus the issue of the time-scale is irrelevant. No amount of time is
enough. It is completely obvious that order and disorder alternate in life, as order seeks
restoration, and that Darwin threw the baby of anything like 'feedback' out with the bath.
We imagine a remote random evolution. But in actual life, we would never bet on it. We see
that initiatives decline over time, and, while they may find refreshment, this doesn't
'just happen' all the time in a continuous fashion.
A useful review of the new issues
of thermodynamics can be found in Hans Christian Von Baer's Maxwell's Demon,
where the issues of 'algorithmic complexity' are beginning to impinge on the
statistics of entropy with the 'new kid on the block', Information. The term 'order' is
very treacherous and is not defined in the various arguments of thermodynamics in a way
that really applies to cultural evolution. There self-organization is very real, but its
meaning is a little different!! What is social self-organization? The order created by
cops, or the loot of market systems created by robbers? Here it's Marx versus Hayek, the
latter a wrongheaded but brilliant prevaricator on Darwinism, who saw there was a problem,
even though his spontaneous evolution is a typical blend of classical liberalism and
evolutionism. Historical systems don't need to apologize for being statist, the
libertarian response being something later. Marx began his life in the world of Hegel's
proto-evolutionism, and his views on Darwin are in part later fabrications. No student of
Hegel would dwell long on Darwin, unless he saw the tidal wave of Darwinism as inevitable,
and what he really thought here is not clear. The book reviews some aspects of
macroeconomics, and distinguishes the 'econosequence' from the general 'self-organization'
of civilization.
Even as a reductionist viewpoint
comes under attack, a real 'reductionism', the cosmic context of life itself, might see a
stepping stone in physics to a real biology in eras unfolding since the Big Bang. Thus
Eric Chaisson, in The Life Era shows there is no inherent reason that evolution
cannot have a proper footing in terms of universal processes. For discussions of the new
field of self-organizing systems, cf. The Arrow of Time (NY: Ballantine, 1990), by
Peter Coveney and Roger Highfield, Ilya Prignone et al., Order Out of Chaos (NY:
Bantam, 1984), Paul Davies The Cosmic Blueprint (1988). Unfortunately,
'self-organization' has two directly opposed interpretations, and the modern market
economy would like to claim the term from what is surely its primordial meaning in the
emergence of civilization: the rise of the state, before the contrapositive of the
interior 'freedom emergence' inside the state, another reason for seeing history break up
into separate 'evolutions'. It was the philosopher Hegel who saw this contradiction first.
He saw that the evolution of civilization (he did not use the term evolution!) was
reacting against its own first structure, more monster feedback. The modern critique of
government-stifled economies is just that, a modern one, and an economic question, not a
thesis of cultural evolution. The capacity of markets to 'self-organize' seems obvious,
but has never been defined properly, let alone proven by any theory, and remains an
observation of the actual functioning of economies starting in the early modern period.
The French government, among innumerable other instances, so strangled its economy with
bad regulation that it actually contracted severely, leading close students with economic
horse sense, climaxing in Adam Smith, to try to decipher what was going on. This heads for
some quite controversial issues! But the attempt of a writer such as Hayek, challenging
Marx, to speak of spontaneous natural evolution of a 'market order' works fine for classic
liberal economies, but isn't a theory of cultural evolution, which has produced all sorts
of economies, and is therefore a more general category. Our approach is different. The
mesmerizing confusion of Adam Smith and Darwin is implicitly foretold in the leftist
reaction of a whole century.
Any critic of Darwinism is beset
with all sorts of nonsense about being 'scientific'. It would be good to say what
this means, if 'science' presumes the value-free analysis of phenomena and the study
of society must by definition assume the evolution of values. If it means the collection
of evidence, then the history of evolutionary research is impressive indeed. But the
claims of theory are a shambles. The question of what constitutes science in the realm
of 'evolutionary theory' has never been clarified. It is obviously
important to remember that science is first about evidence, and Darwinism cannot
provide any really conclusive evidence whatsoever, of any kind, in favor of Darwin's
thesis as this pertains to the mechanism of evolution of, for instance, early man. We have
never really seen what we are trying to explain. The debate confuses theory and data,
explanation or model, and sequential data of record merely suggests the fact of evolution,
without explaining the process involved. Credentials to produce a theory of evolution
therefore do not exist, and the demands they be compatible with the current forms of
science incoherent.
We should not wonder too long at
the difficulty. Evolution is a three dimensional time stream of loose populations
undergoing transformations over centuries, millennia, eons. Experience with a can opener
won't help. The study of eonic effect shows that at a beggar's minimum we should
be able, if our ambition is theory, to model an entire social system over three centuries
in a fuzzy region that is neither bounded nor unbounded, as relative transformation. One
must explain how non-random patterns of independently dispersed artistic creativity occurs
in waves. It is difficult to even visualize any such thing, Cecil Demille's Ten
Commandments won't do it. The only thing comparable is the well-known World Systems
models, which promptly degenerated into bickering over their limited assumptions. And that
was confined to the purely measurable variables available. A real simulation of man's
cultural value evolution must encompass everything in all categories, especially unique
instances and weak evolutionary firsts, as in the arts, to be realistic. The social
sciences have produced too lame-ducks in the realm of theory, Darwinism, and the
macro-economic model. The latter, apart from its general interest, shows insufficient
mathematical potency to get anywhere. There (and the subject is an interesting one,
despite severe criticisms) the problem is clearer, you can't really quantify the
motivations of man, unless you amputate every factor in man except pure utilitarian
quantity. That may be valid economics, but it is not cultural evolution. Everyone turns to
the same book of differential equations, and starts flycasting for some data that will
fit, or else the Newtonian straightjacket is put onto the 'evolution' of an economic
system. It is always the same book of differential equations, and one is better off simply
admiring its contents in the abstract. Here physicists always get lucky, while students of
social science muddle through with one-legged theories that fall over and collapse after a
fashionable run. And the method has graduated in physics to the fabulous strange world of
higher analysis and Hilbert spaces. There we find, not free will, but 'free activity', the
explicit act of measurement by the scientist interacting with an otherwise deterministic
system. We might take note of this contrast of double systems. In any case, this situation
makes clear that complex theories that look scientific may be nothing of the kind. The
point is less obvious in early Darwinism, until, voila, the models of population genetics
are put forth. They might work to a degree with bacteria. But after that their claims are
certainly open to question.
Social systems don't respond so
far to these analytic methods in any direct fashion, as Karl Popper pointed out. If a
theory must predict, someone will be stubborn enough to try and do otherwise. There is no
inherent reason this failure of theory should be so. If mathematics works so well in one
domain of nature, its distant cousin should exist. Thus, at one and the same time, our
eonic 'theory' tries a new way to prove this wrong. We see a hint of an answer. Throw
out prediction, allow free activity, and search for 'trends'. It is a point that has been
better debated in the historical sciences, and by such thinkers as Karl Popper, with his
views on 'historicism'. But this argument also has its flaws. The connection of history
and evolution, notwithstanding the ambitions of sociobiologists, is elusive and the two
subjects remain in two worlds. They quite naturally wish to find one subject in two, to
biologize culture. But first you must have a rock solid theory of general evolution. The
trick to finding this unity is to first abolish it. We have already pointed to our own
'trick' of 'connecting to disconnect' the two subjects. Sociobiologists wish to
biologize ethics, invade culture, create a comprehensive theory. Good idea, much railed
at. But if natural selection fails, it won't work. This discussion sometimes confuses
genetic determinism and Darwinian mechanism. The existence of genetic mechanisms of
behavior is not proof of Darwin's theory. Our 'freedom when' question allows us to
approach the question indirectly, in the gray area between 'free activity' (which might be
robotic) and Free 'free activity', which might, or might not, exist.
Some Critiques of Darwinism
One
of the most comprehensive bibliographies of Darwinism and its critiques
is Origin of the Species Revisited, W. H. Bird, (Regency, 1991)
Also,
Lovtrup
The
literature criticizing Darwinism is considerable and increasing. If
you have never read a Darwin critique, your opinion on evolution is not
worth much. This literature is also treacherous, but is
rendered significant by the strange dogmatism of Darwinian accounts,
which makes criticism easy for amateurs. Beware of claims for the
argument by design, which deserve respect and a hearing, but cannot be
taken as proven. Some critics do in reverse what Darwinists do,
with reversed agendas. The purpose of these critiques should be to
assist in reading the standard literature, beyond its defects, which can
be confusing. The amount of wrong research created by taking Darwinism
at face value is tremendous, a scandal Cf. Icons of Evolution,
by J. Wells for some examples. The religious agendas of some of these
critics will avail them nothing.
The
field of criticism is changing in the age of hox genes, cf. Dear Mr.
Darwin, Gabriel Dover, and Sudden Origins, J. Schwarz
Before recommending some Darwin
critiques, it is important, obviously, not to forget the mainstream
literature, if you can survive it (bibliographies are legion). Always be
wary of the claims made, and, as an exercise, at least, consider that
natural selection is inadequate as explanation without being intimidated
by the scientific wrapping. Critiquing Darwinism is one of the best ways
to become a Darwin student, you will have to think, and dig into the
literature to determine, as an amateur, the thinking of the experts. Not
always easy. but don't abdicate.
Lee
Spetner, Not By Chance, Soren Lovtrup's Darwinism,
Refutation of a Myth, Robert Reid's Evolutionary Theory, The
Unfinished Synthesis, and Robert Wesson's Beyond Natural
Selection, contain general critiques of Darwinism that are very
useful starting points for those confused by the general tenor of
certainty cast about the NeoDarwinian Synthesis. The classic critique is
Denton's Evolution: A Theory in Crisis. W. R. Bird's monumental
two volume work, The Origin of the Species Revisited, contains
5000 references on Darwinism, including virtually all the critiques. The
complexity of the subject makes the challenge seem difficult, but the
basic issues are relatively clear. Cf. Robert Reid, Evolutionary
Theory, The Unfinished Synthesis (NY: Cornell, 1985), Robert Wesson,
