Can I count on your support? Gilbert put it this way in a scientific volume on primate origins: The most biogeographically challenging aspect of platyrrhine evolution concerns the origin of the entire clade.

If monkeys and cats can unconsciously ascend from subjective data to objective conclusions, why must their consciousness be restricted to the subjective? Second, the theory of mind, by which one chimpanzee infers the motives, intentions or feelings of another, depends on applying an analogy.

As Adam Smith , section I. Analogy is also a powerful tool in forming theories Thompson , p. Third, primate social life favors intelligence Jolly Baboons live in troops of eighty.

Each troop has a dominance hierarchy governing access to mates and food or resting sites. A baboon can recognize, by sight or sound, every other troop-mate.

Indeed, Cheney and Seyfarth p. This abstract, elaborate, objective, often tested theoretical construct provides an economical summary of the social knowledge a baboon needs to survive and reproduce Cheney and Seyfarth , p. Ritualized games using these abilities, such as poetry, drama, mathematics and theoretical physics, are a form of social play, an outgrowth of the exploratory curiosity so common in many animals Huizinga ; Lorenz Are philosophers too serious to see how important play is for developing intellect?

Indeed, even if animals other than human beings cannot criticize each other except by punishing, out-reproducing or eating the mistaken, they must live in the same objectively real world we do.

There are no surrogate truths: what they know, they must know truly Lorenz Likewise, Dennett , p. Finally, Nagel p. Although we have yet to fully discern this Tao Lewis , p. There may well be only one set of basic moral rules that ensure a healthy, sustainable social life.

Moreover, perturbing the balance of virtues prescribed by this Tao, exaggerating some and neglecting others, causes massive social suffering Lewis , p. Can natural selection predispose us to discover these rules? First, I suggest that interdependence is the real mother of morality. When it reproduces, it produces haploid gametes, eggs or sperm, with one set of genes apiece. This mutant thus spreads rapidly at first. In homozygous individuals with two mutant genes at this locus, mutants are equally nasty to each other.

Genes at different loci are so interdependent that when this locus fails to function thanks to having two mutant genes, the animal is stillborn or sterile. Moreover, fair competition usually benefits society Smith Curiously, mechanistic selection among genes has done far better than human beings of modern societies in making competition fair.

In sentient animals, interdependence also breeds moral instincts. In Book I, c of his Republic, Plato observed that a gang of thieves only functions effectively if they treat each other fairly. Their unity of purpose depends on treating each other fairly and punishing the unfair Boehm Such responses cannot wait for conscious calculation, they must be rooted in instinctive sympathy for fellow group members. These instincts are deeply rooted: long before it reasons, a baby, like a playing dog or wolf, will cease a form of play that elicits distress in a companion Changeux , p.

By themselves, social instincts do not a morality make. Reason must judge between conflicting instincts Lewis , p. Darwin , p. This is still a work in progress. As society enlarges and interdependence within families and local groups weakens, social instincts weaken also weaken, and reason must take over from natural selection in promoting morality.

Nowadays, reasoned morality is often supplanted by cruder instincts. Lacking other approaches, biologists will push the materialist approach as far as they can. The best of them, like Changeux , will seek full explanations of consciousness, learning and moral judgment. She followed this by Animals and Why They Matter Midgley , a well-written, clearly reasoned assessment of human duties toward animals.

Her writings abound in the plain horse sense so characteristic of Aristotle and Darwin, and so sorely lacking in many modern academics. In this book, she criticizes various aspects of neo-Darwinism and the world-view she thinks it reflects, mostly for what it ignores. We are in fact functional beings whose nerve-cells can do nothing without our bodies: why replace a perfectly good functional explanation by a promised mechanical explanation whose fulfillment no one can yet guarantee, and which, if fulfilled, would probably be much less insightful?

Second, the materialistic world-view underlying neo-Darwinian writings often privileges the objective over the subjective, ignoring mind, intention and consciousness as immune to objective analysis, and too immaterial to affect the material world. She delights p. Indeed, ignoring what our consciousness can tell us is crippling, as the materialist Jacques Monod , p. The mathematician and theoretical physicist Hermann Weyl , p. Chesterton , p. I am always inside a man… but I wait until I am inside a murderer, thinking his thoughts, wrestling with his passions, till I have bent myself into the posture of his… hatred.

Moreover, these divorces have privileged science over the arts and promoted science as the only way of knowing, which has done nothing to enhance either the effectiveness of education or the quality of its content Nussbaum Third, Midgley doubts whether biology can be reduced to physics and chemistry.

Like Changeux , she realizes that the philosophy of matter needs updating p. Nonetheless, she doubts whether mind can be explained entirely in terms of matter.

The laws of physics are the same whether run forward or backward p. More generally, she believes that there are other ways of knowing besides science p.

Fourth, Midgley considers it thoroughly inappropriate to declare the universe meaningless in the name of atheistic materialism p. Like the agnostic Darwin , p. Moreover, she is as hesitant as Darwin to try to destroy the meaning other people see in their lives. Finally, she finds modern selection-theory problematic. She must believe that the true origin of species is more linked to the origin of variation than to natural selection.

She remarks p. She doubts whether, even given adequate variation, natural selection can account for the exuberant variety of life, because p. She does not understand kin selection, which is curious, for its role in the evolution of insect societies seems obvious to most biologists.

She has been unduly excoriated for this failure. You do not currently have access to this article. Download all slides. Sign in Don't already have an Oxford Academic account?

Judging solely from statements such as these, one might conclude that evolutionary biologists have already solved the problem of the origin of new morphologies and body plans, at least in principle. It would seem that all that remains is to fill in the details. Behind the curtain of public pronouncements, however, biologists know that this is not the case. Life scientists have long questioned the sufficiency of known evolutionary processes to solve the problem — and such skepticism continues unabated.

In the introduction to his article, Meyer documents this controversy with extensive citations to the current scientific literature. Meyer cites more than a dozen other scientific publications in the past ten years in which other biologists have written essentially the same thing. These citations are merely a reflection of a decades-long debate within the biological science community.

More recently, in his book On the Origin of Phyla , paleontologist James Valentine evaluates various attempts to explain or explain away the origin of the body plans that arise in the Cambrian. Even Kevin Padian, before he became president of the militantly Darwinist organization in which GME all work as staff members, acknowledged that there is an unsolved problem here.

Instead, all of them are optimistic that materialistic evolutionary processes will eventually solve the problem of the origin of new morphologies and body plans, and they propose various hypotheses that they hope will contribute to the solution. But they unanimously acknowledge the problem. Meyer did not invent it; he simply proposed a different solution.

GME also claim, contra Meyer, that neo-Darwinism or some variant of it can explain the origin of novel forms and structures.

Below is a small sampling of the kinds of papers that Meyer would have had to address in this field in order to even begin to make a case that evolution cannot produce new morphologies. Most new genes and new structures are derived by change-of-function from old genes and old structures, often after duplication. The selection pressure in favor of the structural modification is greatly increased by a shift into a new ecological niche, by the acquisition of a new habit, or by both.

This, in most cases, explains how an incipient structure could be favored by natural selection before reaching a size and elaboration where it would be advantageous in a new role. So Mayr argues that new structures emerge when natural selection modifies an existing structure for a new function.

But natural selection operates only when three conditions are met: first, there must be variations in some trait; second, those variations must affect how many offspring the organism produces i. Mayr provides no evidence that these three conditions are met in any of the cases he describes. At this stage, any enlargement of the surface of the inner throat or esophagus, any formation of diverticles, etc. How Mayr knows what happened in Devonian swamps is a question only he can answer.

At any rate, he provides no evidence for heritable variations capable of producing the traits he describes. As Meyer notes in his essay, building a new body plan or a major new morphological structure such as a lung would require more than minor genetic variations that occur late in development. At the very least such morphological innovations would require beneficial mutations occurring during early development.

Yet beneficial mutations affecting early development have never been observed. Just blow into the mouthpiece and move your fingers up and down on the holes. Would you like to know how novel structures arise during evolution? From existing structures, of course, via new selection pressures. Leading evolutionary biologists, however, seem not to have heard the news. Scientists do not work on problems that others have already solved.

As current scientific literature and professional meetings attest, however, evolutionary biologists today continue to try to solve the problem of the origin of morphological novelty.
