aquatic ape - moore or less

Part 2.

Critics of Jim Moore’s website routinely refer to his addictive dependency on the logical fallacy of Ad Hominem.  As even a cursory reading of the offending website shows, the accusation is well justified. To my mind, however, the terms ‘logical fallacy’ and ‘Ad Hominem’ do not adequately describe the nature of Mr. Moore’s remarks. They suggest that the faults being described are mere technicalities; no more serious than errors of grammar or syntax.  But if we look to plainspoken English to replace such uncommon terms, those that come to my mind are denigrate and belittle. Consider these extracts from Moore’s review of Morgan’s last book ‘The Naked Darwinist’:

She immediately goofs – she doesn’t seem to understand – very confused – science deniers – are a rant – not being entirely accurate – a sort of unctuous, attempt at flattering and cozying up to people, or a pose as a somewhat imperious ”voice of  authority” – doesn’t understand it – doesn’t understand or deliberately confuses – railing against – extended rant – her methods are very similar to those of fundamentalist creationists – a tactic to mislead the reader – she simply doesn’t understand it – gloss over the fact – a massive ego – didn’t do even this tiny bit of research –reality gets thrown overboard – ludicrous to hold Morgan’s idea – cultlike view of  “Darwinism” – used by a host of creationist sources in exactly the dishonest way Morgan does -  it’s truly disturbing to see Morgan adopt their tactics so often – rail against it – without (again) seeming to understand – Morgan here (like a lot of people do) gets confused – her longest running and most ridiculous errors – she gets kind of mad…….

In what purports to be a scientific review of the Aquatic Ape Hypothesis, why does Jim Moore feel the need repeatedly to denigrate Elaine Morgan?  If his concern is solely with the hypothesis, it is pertinent to ask why he is bothering himself to review The Naked Darwinist. As he admits:

So, book read, it turns out not to have anything new, to be simply a regurgitation of  her previous works in shortened form, with even less substance and more whining (whinging for you Brits)….

So if, book read, it contains nothing new, what is there to review?  Why trouble to regurgitate arguments already to be found elsewhere in his website? Not only does he prepare this seemingly redundant critique but extends it to great lengths. Moore admits:

You can see it [Morgan’s many errors and misunderstandings of theory] reflected in the length of this critique, which is somewhat over half the length of Morgan’s book.  I know I can be longwinded ……

The purpose of this longwinded review is, I contend, simply and solely to enable Jim Moore to continue his denigration of Elaine Morgan. The fact that he bothers to review her last book at longwinded length is, I suggest, not simply evidence but proof positive that his target is not the AAT; his real target is Morgan.

A few extracts from the newsgroup ‘sci.anthropology.paleo’ will establish the tone of the relationship between Moore and Morgan. Let a third party, Bryce Harrington by name, act as prologue in this complaint he addressed to Jim Moore:

With the vicious personal attacks you’ve made on Elaine lately, I am not surprised she’s thinking of ignoring you.  She’s shown an amazing amount of patience and resilience and has rarely descended to your level of flames and ad hominem attacks

The exchange Mr. Harrington referred to begins with Elaine Morgan’s request to Jim Moore :This makes it very tempting to let everything with your name on top of it go unread as hate mail. That would be a pity, because on this occasion you were right, the case does need amending, and if I had not read your contribution I would not have realised it. But I do wish you would sound a bit less like the Witchfinder General.

Jim Moore replies: Whether you “let everything with (my) name on top of it go unread” is not a concern of mine.  If you wish to consider anything that isn’t fawningly uncritical adoration as being “hate mail”, you are certainly free to do so.  

This exchange is further proof, if further proof were needed, of Moore’s real motive.   Rather than continue to discuss ‘the case that does need amending’, that is to say to continue discussing the AAT, Moore chooses instead to continue his ‘vicious personal attacks’.  It surely cannot be disputed here, that to Jim Moore, the insults are far more important than the hypothesis.  

Jim Moore does not even attempt to criticise the Aquatic hypothesis.  Nowhere in his long ‘scientific’ critique does he show, or even try to show, that the evolutionary history of humankind could not possibly include a semi-aquatic episode. No matter how many false facts he claims to find in the arguments of Morgan, the hypothesis itself contains no false facts because the hypothesis contains no facts whatsoever.  It maintains simply that many characteristics unique to humankind as a terrestrial mammal can ( ‘can’ not ‘must’) be explained by positing a semi-aquatic episode in its pre-human (hominin) past.  

 As long as an hypothesis does not offend any established scientific fact, it can claim some validity - whether or no the scientific establishment gives it recognition. Like all other current attempts to chart the evolution of our species, the Aquatic Ape Hypothesis is a speculation; a scenario; a just-so-story. So even if Moore’s readers can stretch their credibility to somewhere beyond the limits of the known universe and so able to accept all of his criticisms; to be convinced that Morgan’s army of argumentative men are made of straw; that each and every one of her facts are proven false; that she is totally ignorant of evolutionary theory, the her every quotation is a misquotation, even then Moore has established no more than Morgan’s inadequacies as a proponent of the AAT.  The hypothesis itself remains unscathed.

  The individual proponents of an hypothesis each put forward their particular arguments; but in order to counter the hypothesis, its opponents must do more than merely criticise these arguments.  The opponent must attempt to bring forward proof that the hypothesis ‘must’, not ‘might’, be wrong.  It is generally believed impossible to prove a negative; which means that it is not possible to prove that something did not happen. So it is impossible for Jim Moore to establish that our hominin forebears were never semi-aquatic. From the start he is backing a loser. In order to demonstrate his contention that no such aquatic creature has ever existed, he should produce, if not proof positive, at least a preponderance of evidence of an alternative and superior explanation.  Elaine Morgan once advised Jim Moore to invest his talents into devising an hypothesis that would ‘knock Alistair Hardy’s into a cocked hat’. It was sound advice. If this is beyond his capability, he could instead make a detailed comparison between Nancy Tanner’s more fact-oriented hypothesis and what he considers to be Elaine Morgan’s poorly researched compendium of ridiculous ideas.

On page 20 of ‘The Naked Darwinist’ Morgan writes:
I expected some scholarly figure to be invited into a studio where he would say “The points the author fails to take into consideration are (a) and (b) and (c).  These facts alone render her idea unacceptable.”

Because, at least in his own estimation, Jim Moore is conversant with every facet of evolutionary theory and from his vast knowledge is able to correct all Elaine Morgan’s “false” facts, he should easily be able to provide facts (a) and (b) and (c) and so put paid ,once and for all, to the pesky hypothesis. He does not even attempt this simple, parsimonious method of refutation. He does not try to assemble the few facts necessary to prove the hypothesis untenable. Instead, Jim Moore goes through Elaine Morgan’s books with the finest of fine tooth combs searching for any and every statement that he can criticise, then taking the opportunity of levelling a broadside or two of derogatory remarks at the author. But why?  For what purpose? To what end?

Jim Moore seems to believe that in criticising the works of Mrs. Morgan he is protecting the scientific community from contamination by a theory full of false facts. He invokes a quotation from Darwin to his aide: “False facts are highly injurious to the progress of science, for they often endure long…”

Darwin’s remark makes sense only if the false facts are accepted as true by science; only then can they be injurious to its progress. There is an infinity of false facts; two plus two equals five, or six, or seven and so on to infinity; potatoes grow on banana trees; a tripod has four legs; false facts would fill the Library of Babel twice over.  But none of these are injurious to the progress of science because science does not accept any of them.  Nor, as Moore is ever ready to remind his readers, does it accept the Aquatic Ape Hypothesis. Since none of its facts, false or otherwise, are of the slightest interest to science, none can cause the slightest injury to its progress.

So, if Moore is not able to prove the impossibility of an aquatic ape; if he is not valiantly defending the integrity of science against the strawmen hordes of Morgan’s 'false' facts; then what is he up to?  What he is up to, I suggest, is the defamation of Elaine Morgan. Although his website takes the form of a critique of the AAT, its primary purpose, I believe, is to provide a convenient platform from which to lob incessant insults at Elaine Morgan - with an occasional sideswipe at anyone who has the temerity to give an approving nod towards the AAT. Moore’s website ‘Aquatic Ape – Sink or Swim’ would be more accurately entitled ‘Elaine Morgan – Dishonest or Deluded’.
     
In her final book ‘The Naked Darwinist’, Elaine Morgan has written:-

“That book, The Descent of Woman, became a best seller, and in the United States it was a Book of the Month selection.  I became a minor celebrity, ferried around America coast-to-coast for a couple of weeks, appearing on the top chat shows.”

Moore’s method in reviewing the writings of Morgan is to scrutinise them painstakingly, word by word, criticising wherever he can. It is notable that his reading of the passage above recording Mrs. Morgan’s ‘minor celebrity’ in America does not raise his hackles; his critical comb picks up nothing worthy of disparaging comment. Surprisingly, he does not jump at the opportunity of pointing disdainfully at Morgan’s conceit in thinking the whole of the USA was rushing from the local bookstore clutching its treasured copy of her ‘Book of the Month’ so as to be home in time to see her next riveting interview on TV. Perhaps the book's popularity and its author’s celebrity remain a sore point to Jim.

Because of the publicity, it is presumed that ‘The Descent of Woman’ came to the notice of Professor Nancy Makepeace Tanner and her helpmeet, Jim Moore. Were they impressed by its feminist agenda or were they irritated by the remarkable success of a book dealing with the very matter - the role of the female in human evolution -  which was to be the subject of Nancy Tanner’s intended scientific research?

Jim Moore does not give the book ‘The Descent of Woman’ his usual microscopic inspection.  His comment is limited to a few uncharacteristically short-winded words: Elaine Morgan, at the time an Oxford grad in English and a TV scriptwriter, entered the scene in 1972 with the book ‘Descent of Women’ (sic), the idea for which she got from Desmond Morris’s book.  This was a pop book, with a pretty chatty style which seems dated now but was popular then, and it sold quite well. Looking back at it, I wouldn’t call it particularly female-oriented (compare Morgan’s notion of early female hominid behaviour being the result of continual rape to more fact-oriented ideas like Tanner and Zihlman’s idea of the selective power of sexual choice by females in hominid evolution), but Morgan presented it as “the” alternative to what she then called “The Mighty Hunter” theory.

Perhaps Moore tip-toes warily around the book because to give it his usual detailed review might expose the origin and nature of his animosity towards Morgan.     

The professor’s book ‘On Becoming Human’, published some nine years after ‘The Descent of Woman’, has much in common with Morgan’s book. On page three of the book, Tanner writes:
“The English language in which man can refer to humans in general as well as be used in its more restricted sense to refer to the male gender per se, reflects and reinforces the Western cultural tendency to focus on males”.

This observation is paralleled on page nine of Morgan’s book:
 - the fact that ‘man’ is an ambiguous term.  It means the species; it also means the male of the species. …..I believe the deeply rooted semantic confusion between ‘man’ as a male and ‘man’ as a species has been fed back into and vitiated a great deal of the speculation that goes on about the origins, development, and nature of the human race.

Both stress the primacy of woman the gatherer over man the hunter as the developer of tool use:

Morgan (page. 27):  One idle afternoon after a good deal of trial and error she picked up a pebble – this required no luck at all because the beach was covered with thousands of pebbles – and hit one of the shells with it, and the shell cracked.

Tanner (page 268): By gathering with tools, early mothers could obtain enough food for themselves and to share with their young, even on the savanna.  It is therefore, highly probable that it was women with offspring who developed the new gathering technology and that this was the innovation critical to the ape-human divergence.

Tanner (page 259): It would be those mothers who invented and used stone tools as dental substitutes.

Amongst other similarities is that both dismiss the baboon as a suitable model for early hominin society and both were written for the same general readership.  Although the author of ‘On Becoming Human’ is a professional anthropologist and the book full of the references and acknowledgements required of a scientific work, it is also replete with a variety of line drawings including Victorian ladies, Thai dancers, chimpanzees aplenty and even a member of the rock group ‘Kiss’.  On page 11, the professor writes:

“This chapter is, necessarily, rather technical, and some readers may prefer to skim or skip parts of it on their first time through the book.”  

The ‘some readers’ referred to are, presumably, those without a scientific background and so, like ‘The Descent of Woman’, the book is intended to popularise the  view that  women and, particularly, mothers, played a critical role in the evolution of humankind. It is the dissimilarities, however, that are the more significant.  It is to be expected that, because Elaine Morgan was a professional writer, her book is written in a more attractive and engaging manner – or as Moore describes it a ‘pop book, with a pretty chatty style’ – so much so that after forty years and many reprints , it is still readily available. More importantly, whereas Nancy Tanner sets her hypothesis in the scientifically respectable ‘mosaic’ – which as a non-scientist I take to mean any part of the African continent excepting the densely forested areas -  the radical Elaine Morgan dunks her hypothetical hominins first in then out of the water.

My speculation is that Nancy Tanner returned home from her years spent studying a gatherer- hunter tribe in Sumatra, her feminist mind musing on the male dominion over current evolutionary theory and, in her own words “seeking to correct what has been both a ludicrous and a tragic omission in evolutionary reconstructions” only to find that another feminist had already made a well received attempt at the correction,   An obscure foreign TV playwright, Elaine Morgan (Elaine who?) had, literally, flown in out of the blue, trespassed on the intellectual preserve of anthropology and become a minor celebrity on the basis of her ‘Book of the Month’. It was as though someone had crossed the finishing line before Nancy had even chosen her running shoes. The title Morgan had chosen for her book - ‘The Descent of Woman’ - might also have been somewhat galling. On page 167 of her book, Tanner comments:

He [Darwin] was prevented from harvesting all the fruits of his fertile imagination because he did not follow through with the logic of his own argument – to discover how female choice influenced the origin of the hominids; that is, to show how sexual selection was important at the very onset of human evolution.  Because of an unfortunate blind spot engendered by his own cultural background, Darwin was unable to explicate the necessary interrelationship and carry his work to its more logical conclusion.

It is clearly evident that Professor Tanner considered her book to be developing Darwin’s work along the logical path that, had his imagination not been fettered by the constraints of Victorian England, he himself would have explored.  So what better title for such a work than the feminisation of Darwin’s ‘The Descent of Man’?  Unfortunately, due to the unexpected, unwelcome and untrained amateur contender, E. Morgan, that prize title, ‘The Descent of Woman’ had been won for the Principality of Wales.


I am supposing then that Jim Moore was irritated by Morgan’s successful ‘pop’ book; and that the cause of his negative response was not the Aquatic Ape hypothesis.  It was the feminism that caused the suggested resentment felt by Jim and that this resentment motivates his ‘Aquatic Ape- sink or swim’ website. Although the website takes the form of a critique of the AAT, its primary purpose is to provide a convenient means of expressing his animus towards Elaine Morgan.


Before examining Moore’s critical techniques it will be helpful to consider his general intellectual stance.  In this review, in all his reviews of Morgan’s books, in his contributions to the newsgroup ‘sci.anthropology.paleo’ Moore assumes the role of omniscient polymath. Whatever the subject, Moore is an authority able to instruct others of a lesser intellectual breed.  Consider the following illuminating exchange:

Brian Doyle asks: “If a species forces another species into extinction, i.e. Humans hunting animals, either by pollution or other conventional means, into extinction, is this considered Natural Selection?

Greggory Senechal replies: “I’m going to go out on a limb and say no. I look at Natural Selection in a more positive light.  Characteristics are selected in, not selected out.  If some animals tunnel underground, protecting themselves from human hunters, the “tunnelers” might be selected in.  Does that make sense?

Whereupon our Jim, bristling with absolute certainty, storms into the fray:” No” he thunders. “It’s “Natural Selection” all right, no matter how “unnatural” we might think of it.  It’s no different really than, say, a hurricane or two wiping out a small, nearly extinct population.  And I would also think of natural selection with different words than you use (the “in” or “out”, or ”selection for” [a similar phrasing]. Natural selection works only by basically wiping out organisms; it “selects” by not “allowing” effective raising of young (at any stage of that process) (and my quote marks are proliferating because of the inherent problems and baggage associated with words like *allow” and “select”).  In that sense, natural selection only selects “against”, never “for”.  It only happens when something “doesn’t” work, and the fact that things that ‘do’ work are left (and sometimes get” better”) is an artefact.  Sexual selection, OTOH , is an active selection “for” traits.

In this enlightening exchange, the tentatively questioning Greggory, doggedly hanging on to his limb, reveals his true understanding of natural selection – his tunnelers would of a certainty be more likely to survive the hunt and so able, by procreation, to pass on their tunnelling characteristics to the next generation; whereas the all-knowing Jim shows that when it comes to natural selection he is completely out of his depth; drowning in a high tide of quotation marks.  Natural selection is nothing like a hurricane that wipes out a small population; nor even like the meteorite that supposedly put paid to the whole caboodle of dinosaurs. Such catastrophes are evolutionary tragedies; histories of genocide written in the rocks by old father deep-time; but nothing whatsoever to do with natural selection - except to provide opportunities for it to exploit. The baggage of which Moore complains is not attached to the offending words but cluttering his confused misunderstanding like abandoned luggage. He needs to enclose so many words within quotation marks because he understands none of them in a Darwinian context.  And as for ‘artefact’ - things that ‘do’ work are left (and sometimes get” better”) is an artefact.  Artefact?  Being no scholar I assumed my understanding of the word might be in error so I sought reassurance in Chambers Twentieth Century Dictionary:

Artefact, artifact, n. a thing made by human workmanship.

So here we have it; according to Moore,( a sort of Pope Jim the Infallible handing down his papal bulls), after natural selection has wiped out the organisms that didn’t appeal to its taste, everything thereafter that works can, according to Jim, be made by any smart gal with a half  decent workshop.  I really think it’s time to move quickly on before Jim manages to struggle free of those two large, kindly gentlemen in white coats trying to coax him back into his straitjacket. 

Jim Moore’s belief that natural selection is a negative process, that it always selects ‘against’, never ‘for’, must have occasioned certain tensions when he was assisting Professor Tanner with her book ‘On Becoming Human’. Their harmony must have hit repeated discords when she wrote:

….(page 271) selection for decreasing sexual  dimorphism also continued during early human evolution ….. (page 222 ) Selection was for increasingly efficient, time-saving, energy-saving ways of getting food ….. (page 209) Selection for early intelligence is one basis for expanding brain size and more sophisticated mental capacities. (page 161)  For gathering females, natural selection for bipedalism and tool use in the food quest was intense. (162)…. must have been strongly selected for….

(My underlining)

And how can ‘wiping out’ be the defining characteristic of natural selection when all organisms, without exception, are wiped out?  Darwinism is concerned not with the wiping out but with the happenings before the wiping out occurs.  Then out of the confusion, as welcome as it is unexpected, emerges a glimmering of truth. Jim turns momentarily away from his doom mongering and announces: it “selects” by not “allowing” effective raising of young.  Had our sunny Jim defined natural selection simply as a concern for the effective raising of the young, the Darwinian ranks of Tuscany could have scarce forborne cheering themselves silly. Pity ‘tis that this little ray of light should be obscured, scarcely discernible behind her thick veil, as she follows the mourners at the mass funerals of those wiped out by the serial murderer ‘Natural Selection’.


In his eagerness to contradict Morgan’s every statement Moore often succeeds only in contradicting himself. In his website Jim Moore makes many references to Morgan’s strawman version of the savannah:

….a favourite technique of hers, constructing a savannah strawman….Morgan constructs her strawman….she gets out her strawman kit again……

Moore claims that for the last hundred years the savannah has been defined as a type of woodland characterized by a very open spacing between its trees and by intervening areas of grassland.

In ‘On Becoming Human’ Nancy Tanner gives a more comprehensive description:
About half the surface of Africa is covered by dry savanna and grass steppe or by open woodland and mixed savanna.  These areas are a mosaic landscape that includes open grasslands, scattered tree clumps, riverine forests, gallery forests and marshy areas.     

Whatever the savanna is, it most certainly is not, according to Moore, hot and dry.  Such a description is Morgan’s strawman version.  Then in his review of ‘The Naked Darwinist’ the unwary Jim, not looking where he is putting his feet, turns his attention to Professor Peter Wheeler of the Faculty of Science at Liverpool John Moores University.

Peter Wheeler's "radiator hypothesis" -- briefly, very briefly, Wheeler has done a series of papers describing his studies of how shorter body hair arranged as human body hair is arranged, along with human style sweating, is an immense aid in cooling in a hot, dry, relatively open area, allowing the use of that environment at times when other animals find it difficult, or even effectively impossible, to utilize it. So Wheeler, using accurate descriptions of our body hair and sweating abilities, was able to show how our hair and sweat characteristics would be an advantage in dry hot areas, and observations from cultural anthropologists show how this was indeed effective, for instance in persistence hunting -- also very briefly, "chasing antelope or other game in the midday heat, often for hours,

(My emphases.)


By acknowledging that, regardless of current understanding, science once accepted that the habitat in which Homo sapiens evolved was hot and dry, Jim Moore here admits that Elaine Morgan was correct in her claim and that his silly strawman jibe needs, belatedly, to be thrown out of the window. But having put one foot in it, our Jim insists on putting in the other.  This hypothesis, with the mighty hunter chasing after antelopes, often for hours in the midday heat, is surely an exemplar of those ‘reconstructions’ which incurred Nancy Tanner’s disapproval. It is typical of the exclusively male accounts of human evolution which Tanner describes as ludicrous and which, by failing to give attention to the evolutionary role of the female as mother, she regards as a tragic omission in evolutionary reconstructions. So it seems that his own argument having required him to heave his ‘strawman’ absurdity out of the window, it now requires Jim to defenestrate Nancy Makepeace Tanner together with her misguided matrilineal hypothesis.

Jim has left the window wide open and had his phylogeny equipped him as a triped, is now preparing to put his third foot in it.  Having confidently commended Peter Wheelers account of hair loss and sweating prowess, he announces with his usual unchallengeable authority:

She’s (Morgan’s) long been solidly against even any invocation of sexual selection, probably because many of the features she seeks to explain via natural selection – hair, sweat, fat – are classic cases of sexual selection.

 So much for Peter Wheeler’s explanation of hair loss by natural selection. The Liverpool Professor would have better spent his time in the Cavern listening to the Beatles instead of sweating it out in the heat of Africa concocting daft hypotheses. So out of the window goes Peter’s sweaty hunter landing atop Morgan’s strawmen and Tanner’s female gatherers.

It is conceivable that Jim Moore could gather together these apparent contradictions and construct from them a cohesive scenario. But he has no such a positive ambition.  His sole aim is to belittle Elaine Morgan.  So when she proposes that our reduced  hairiness is due to a watery environment, he wheels out Wheeler to contradict her.  And when she seemingly ignores sexual selection, Moore dumps the now useless Wheeler and his strawman savanna so that he can continue his contradictions.

To me the great conundrum is why such eminent intellects as P. Z. Myers; John Hawks and Greg Laden should find Moore’s website so compelling.  According to P. Z. Myers it is ‘definitive’; that is to say it is the final word. Thanks to Jim Moore, P.Z. tells his readers, the Aquatic Ape Hypothesis has been destroyed beyond reconstruction.  Jim Moore has given it the last rites. 

To me this trinity of eminent academics add justification to the remark of the philosopher Daniel Dennet:

During the last few years, when I have found myself in the company of distinguished biologists, evolutionary theorists, paleoanthropologists and other experts, I have often asked them just to tell me, please, exactly why Elaine Morgan must be wrong about the aquatic theory.  I haven’t yet had a reply worth mentioning, aside from those who admit, with a twinkle in their eyes, that they have also wondered the same thing.


The three scientists, seemingly unable between them to provide any convincing scientific rebuttal of the aquatic theory, would better remain of the twinkle-eyed persuasion rather than put their reputations at risk by an alliance with Mister Jim Moore.
