Description:

"False facts are highly injuriousto the progress of science, for they often endure long; but false views,if supported by some evidence, do little harm, for everyone takes a salutorypleasure in proving their falseness: and when this is done, one path towarderror is closed and the road to truth is often at the same time opened."Charles Darwin, 1871 The Descentof Man and Selection in Relation to Sex, Chapter 21, page 909.The Aquatic Ape Theory (often referred to as the AAT or AAH -- I'll generally refer to it as the AAT/H on this site)says humans went through an aquatic or semi-aquatic stage in our evolution and that this accounts for many features seen in human anatomy and physiology.Using the principle of convergent evolution, it says that life in an aquatic environment explains these features, and that a transition from ape to hominid in a non-aquatic environment cannot. This web page offers a criticalexamination of the Aquatic Ape Theory, treating it as a serious scientific theory. It is one of the few online sources that does so. There are manyother web sites which deal with it, but they do not offer the criticalexamination which any theory needs to be given.1) Because AAT/H proponents askwhy don't people take their theory seriously as science, and the way youtake a theory seriously as science is to examine it for accuracy and criticizeit where it falls short, because...2) "Valid criticism does youa favor" Carl Sagan, page 32 of The Demon-Haunted World (1995).I am doing what many AAT/H proponents-- including its principal proponent, Elaine Morgan -- have repeatedlyclaimed they want done: treating the AAT/H as befits a serious scientifictheory.Accepting any new theory uncritically is foolish.When doing a critique of any theory of human evolution,you check the facts the authors use to support the theory.All scientific theories needto be examined for accuracy; it's an essential component of the processof science. I'm afraid that when the Aquatic Ape Theory is examined, itdoes not fare well. The AAT/H is built on many supposed facts which, whenexamined, do not turn out to be true.Perhaps the kindest thing wouldbe to ignore it, but I am not that kind.Instead I've begun an ongoingresponse of pointing out errors of fact, errors in theoretical understanding(which, though critically important, is more problematic because a lotof people seem to think this is waffling), and urging the theory's proponentsto respond to valid objections to their theory.It shouldn't have to be pointedout that when someone produces a theory or hypothesis and calls it science,it is perfectly legitimate to look at the facts used to support it. While I've been doing this with the facts which are supposed to support the AAT/H,I've found some people don't think this is a legitimate thing to do. Well, it's not only legit, it's absolutely necessary. That's how science works; without this process, science is simply dueling beliefs, with noprogress. The process of examining evidence and discarding inaccuraciesis crucial to the ongoing process of science.There are a number of claimsmade by AAT/H proponents, and tracking down the source material which supposedlysupports these claims is not always easy. In a dramatic departure fromthe way science is supposed to work, references for specific AAT/H claimsare not always available; many times the author(s) involved simply makea claim without any reference to a source of evidence for the claim.For instance, during the period I put together most of the evidence forthis site, chief AAT/H theorizer Elaine Morgan was posting regularly in thesci.anthropology.paleo newsgroup, and claimed to be willing to supply referencesfor her written AAT/H claims, but she proved to be reluctant to provide thesereferences to people who have a past history of actually reading the sourceand reporting back what it really says.Others -- who didn't engagein this sort of "anti-social" behavior -- reported they have no problemgetting references from Morgan.Nevertheless, a number of theclaims made by Elaine Morgan and other AAT/H proponents have been tracked down andexamined. The results are not encouraging.Quite frankly, when Ifirst read the work done on the AAT/H, I saw some big holes in the reasoning,but I did think that the evidence which was (sometimes) given was probablyaccurately and fully reported. When I started looking these things up,however, I found that I was wrong on that count -- the AAT/H has proven tobe a hotbed of those "false facts" Darwin referred to.I don't have any formal credentialsin evolutionary science, so how can I expect you to believe what I tellyou instead of what AAT/H proponents say?Leaving aside the fact thatall the major AAT/H proponents also lack such credentials, you simply lookat whether or not what I say matches actual, known facts.On this site I try to provide references for my statements, and appropriate, unalteredquotes from relevant sources to back up my facts.The more curiousor enterprising amongst you may wish to read further about some of thesefeatures, and you'll find that easy to do by simply going to a libraryand picking up one of the books or journals I mention.If you try to do the same with most pro-AAT/H accounts, you'll find one of several problems:they often don't give a reference for a statement or quote at all; whenthey do the reference is often incomplete (just a name with no clue asto what publication or year the info is supposedly from; sometimes even a wrong name).On this site, I've tried to tie as many of my statementsto specific references as I can; at present this is still incomplete andwill be rectified during my updates.Pro-AAT/H accounts alsocommonly use quotes which are altered to "say" something the quoted persondidn't actually say; they leave out relevant material from the same sourcewhich contradicts the AAT/H position; or they simply claim the source saysthe opposite of what that source actually does say.You won't find those problems here.If you do find an error on my site, please contact me -- there's a feedback link on most pages.I got started on this subjectthrough reading and posting in various science newsgroups during the earlydays of the web.I've got a knack for library research and I likethe detective work that's needed to find an appropriate source of information.I've also had an informal background in anthropological research, helpingmy late wife, Nancy Tanner, with her research on human origins, matriliny,and social organization.This entailed finding, reading, and learningto understand a lot of info that I didn't know, such as molecular studies.In the process, I've learned that my knack for research also includes anability to translate some pretty heavy technical jargon into English, andexplain some complicated subjects in relatively simple terms.This ability to ferret out information sources from often obscure clues camein handy when I started to examine the evidence offered for the AAT/H.The references for AAT/H statements, when they are given at all, are oftenmaddeningly incomplete or misleading.For instance, it took somehunting to find the source for a quote when the quote supposedly came froma "famous authority during a television programme" (it was actually a 1929book by Prof. Frederick Wood Jones).Another time the sourceof information for a claim was said to be a 1979 book, with an author mentioned.Finding the ref then started with finding that book, then finding the onepage out of hundreds (which wasn't given) that referred to the actualreference which contained the info (a 1956 article), then finding the articlewhich contained the info, which, it turned out, didn't actually say whatthe AAT/H proponent claimed it did.To complete the critique of thatone AAT/H claim (about seal sweat) also required finding yet another article,and a total of perhaps 6-8 hours of actual research time.I'll guarantee you the original one paragraph AAT/H bogus claim didn't take that long tochurn out... and people wonder why anthropologists don't spend their timeand meager research grants chasing down AAT/H claims.So I guess I'd say my qualificationsfor this work are 1) a knack for library detective work, 2) an abilityto learn basic scientific precepts (anyone should be able to do this one),and 3) being just a little bit nutty, cause those examples I just gaveshow you've got to be a little crazy to do it.As a note, let me state thatI am not the Jim Moore who is a primatologist at UCSD, noram I the Jim Moore who wrote and cowrote several books on Darwin, nor theJim Moore who's an anthropologist at CUNY.Although I'm not them,from what I've seen of their work, I wouldn't be insulted to be mistakenfor any of them.I hope they feel the same.I'd like to thank the postersin the old sci.anthropology.paleo newsgroup, in particular Phil Nichollsand Alex Duncan, for pointing out many false facts and methodological errorsin the AAT/H's arguments.Their research was helpful to me many times.This site is a partial update and redo of a site I had up several yearsago, and I will be continuing to update it whenever I have the chance.In surfing while rewriting and addingto this site, I've noticed several AAT/H boosters make the rather odd criticismthat my previous site was old, as if that somehow made the facts therein wrong.Although many of the facts posted on this site were firstposted on my old site in 1995, they are still valid.The facts have not changed.The diving reflex has been present in terrestrial mammalsfor centuries, it was in 1995, and it still is, despite the AAT/H claim to the contrary.Salt hunger has been present in humans for centuries,it was in 1995, and it still is, despite the AAT/H claim to the contrary.The infant swimming response has been present in terrestrial mammals forcenturies, it was in 1995, and it still is, despite the AAT/H claim to the contrary.Hymens have been present in terrestrial mammals for centuries,they were in 1995, and they still are, despite the AAT/H claim to the contrary.I could go on, but you'll see all these facts as you go through the site.Suffice it to say that there have been valid objections to the AAT/H sinceits inception, and there still are.Established facts, as opposed to the AAT/H's many "false facts", do not change.I've also noticed a criticismthat I simply engage in ad hominem attacks on AAT/H proponents, inparticular Elaine Morgan.This is a peculiarly funny sort of criticism, sinceit is in itself a variation of an ad hominem attack, that is, instead of attackingthe accuracy of what I'm saying, it attacks how I say it.This is a classiclogical fallacy, one of several that AAT/H proponents often engage in -- there'sa link to a site on logical fallacies on my links page.The thing is, I go after the accuracy of what these people say, and, yes, I have an aggressive style.But pointing out that someone made an error, or altered a quote, or said that a scientist said one thing when they actually said the opposite, is not an ad hominem attack.Frankly, it's doing them an enormous favor, as Carl Sagan stated in that quote.(This does, of course, assume they're trying to do a good, accurate job at what they're saying.)It may not sit well with everyone, but quite frankly, I findit really annoying when good science is taken to task for not acceptinga theory which is so full of holes and mistruths, and which is argued for so dishonestly.And, by the way, not only are honest scientists harderon each other than I am on Morgan, Verhaegen et al., any honest scientist is harderon their own work than I am on Morgan, Verhaegen et al.Navigation note: You can navigatethrough this site's pages by simply
