First, a definition makes no claim so there's nothing to support. It is just a way for me to ensure that when I use the term, a reader will know what I meant by it. Second, I am merely conforming with Richard's usage. *He* uses "human" as if it was synonymous with "no significant differences from modern humans", since his claims would make no sense otherwise.  I wanted to point out that scientists do not use "human" that way: they often use it to refer to species such as H. erectus and H. habilis that they consider evolutionary ancestors of H. sapiens. > When Jim says "All scientists agree that H. erectus and habilis are non- > human", this is simply not true.

Has a single one of these 2,500 members published an article in a peer-reviewed journal showing claiming that H. erectus and/or habilis are modern humans? Is a single one of these 2,500 a paleoanthropologist that would even be qualified to do so? If so, let's hear some names. > > RM > >>> There are cases where overenthusiastic Darwinists have tried to > >>> introduce a new species in order to prove the existence of a missing > >>> link, but where later, scientific accuracy prevails and the 'missing > >>> link' is discredited. > > > >JF > >There are some such cases, such as Louis Leakey's "Zinjanthropus" (now > >known as A. boisei) which you mentioned.

True, you did give references to two scientists who think the australopithecines are not ancestral. What you don't mention is that their views are almost universally rejected, and you don't provide any reason why we should accept their opinion rather than everyone elses. You didn't provide *any* references to support your claim that H. habilis and H. erectus are "discredited" as "missing links". > RM > >>> Is Jim saying that he knows of cases where names are not an accurate > >>> guide because fossils described as _Homo_ are in fact apes, or cases > >>> where fossils described as ape are in fact human? > > > >JF > >I do not claim that any Homo fossils are apes, or that any > >Australopithecus fossils are human.

Huh? I fail to see how this is any sort of an admission, let alone a damaging one. All I am doing is refusing to accept the premises of a question which seems to assume a priori that no ape-human intermediates exist. Richard goes on to accuse me of using a definition of ape-human intermediates which is non-falsifiable. The truth is the exact opposite. My above claim would obviously be falsified if such creatures did not exist. > Jim (and most > other modern Darwinists) are here trying to square a circle that has so far > defied them.

The fact that erectus and habilis are assigned to the genus Homo doesn't exclude them from being intermediates; it only means that the differences aren't considered enough to assign them to a separate genus. > > >JIM FOLEY - > > > > > >..............

I accept Leakey et al.'s type description of H. habilis as a pre-human ancestor (Nature, 202:7-10, 1964). I accept Dart's type description of A. africanus as a man-like ape (Nature, 115:195-9, 1925). If it's a matter of public record, it should be easy to answer my question: Who did these "type descriptions" which assigned Homo habilis and erectus to humans? The definitive references on the H. habilis fossils which I'm aware of (Tobias 1991 and Wood 1991 listed above, both of whom have worked on these fossils for decades) certainly aren't dismissing them as evidence for human evolution. > > >JIM FOLEY - > > >That seems odd to me.

An alternative and far more probable explanation is that > the confusion was caused by Darwinist ideologues like Leakey wrongly > attempting to claim 'missing link' status, How can you blame creationist confusion on evolutionists? After all, ER 1470 was found 25 years ago, time enough one would think for any initial confusion to be resolved. And yet ER 1470, which you say is human, is claimed by Duane Gish to be an ape. Are you saying Gish is so incompetent that he can't tell the difference between an ape and a human? P.S. elsewhere in your post you said Leakey was the first to call Homo habilis human, and here you say that he was wrongly attempting to claim 'missing link' status. Which is it? > but being dismissed by calmer more rational consideration as in the > example I provided. As I said, the scientists whose nomenclature > eventually _prevailed_ were not confused -- only the original Darwinist > claims. So whose "calmer more rational consideration" was it which eventually "prevailed" over Leakey's claims that habilis was a pre-human ancestor? References to the scientific literature, please. Who "prevailed" over the idea that erectus is a primitive human? Who "prevailed" over Dart's claim that africanus was a man-like ape? Zuckerman and Oxnard?? You jest. Zuckerman's views are entirely discredited, and Oxnard is in a very small minority. > >I agree, the scientists were not confused.

Oh? Your source, John Reader's "Missing Links", says of Schaaffhausen's 1857 report ('1875' may be a typo) that: "Shaaffhausen was convinced that the remains were ancient and human; but the limb bones were exceptionally thick, he remarked, with pronounced muscle attachments denoting an extremely powerful individual. The strange shape of the skull was due to natural conformation, said Schaaffhausen, but was quite unlike any modern race, even the most barbarous."

What page number would that be? I can't find it in my copy. > Finally they observed that if he were given a bath, a collar and > tie, Neanderthal Man would pass unnoticed in the New York subway. Not exactly. They said: "Notwithstanding, if he could be reincarnated and placed in a New York subway - provided that he were bathed, shaved, and dressed in modern clothing - it is doubtful whether he would attract any more attention than some of its other denizens". > Today Neanderthals are recognised as Homo sapiens -- a virtually complete > u-turn on the original identification.

Basilosaurus was misnamed because the original describer was not very competent; Richard Owen a few years later had no trouble recognizing that it was a mammal and not a reptile. Milton's claim that species such as H. habilis, A. africanus, A. afarensis were so named because the people who named them considered them apes or humans is just blatantly wrong. *All* of these species were named by scientists (Dart, L. Leakey, Johanson, etc.) who considered them human ancestors and ape-human intermediates. > JF > >2.

The nomenclature can't be changed, even if people think it is misleading, for the same reason that Basilosaurus' name hasn't changed: "These "southern apes" of Africa have turned out not to be confined to southern Africa, nor are they apes. However, because of the stringent rules of the International Code of zoological Nomenclature, which govern the naming of taxa, Dart's name cannot be altered." (Johanson and Edgar, "From Lucy to Language", p.117) > As I said above, Dart chose his nomenclature with care because he > could see the pitfall that Darwinists are rushing headlong into in > their eagerness to make Australopithecus a human ancestor. Nonsense (and how would you know what Dart's motivations were?). No-one (with the possible exception of Broom) was more eager than Dart to make Australopithecus a human ancestor. His 1925 paper (Nature, 115:195-9) was *full* of evidence about the human characteristics of the Taung child. He clearly considered it a human ancestor: "It is manifest that we are in the presence here of a pre-human stock, neither chimpanzee nor gorilla, which possesses a series of differential characters not encountered hitherto in any anthropoid stock." He called it Australopithecus because although he considered it an ape-human intermediate, it was more similar to the apes than to modern humans: "It is therefore logically regarded as a man-like ape." [rather than an ape-like man] See also Reader's "Missing Links", which is quite clear that Dart considered his find an ape-human intermediate. Dart even proposed a new zoological family to put it in: the Homo-simiadae, or "man-apes". > JF > >4. It is a demonstrable fact that many scientists consider Australopithecus > > a human ancestor.

But before you claimed that scientists named it Australopithecus because they *didn't* think it was a human ancestor, and now you're admitting that scientists *do* think it is a human ancestor. > Indeed, you could have gone further and added that _all_ the articles on > paleoanthropology published in _Nature_ show diagrams of how humans have > descended from apes. Actually most paleoanthropology papers in Nature have no such diagrams; you can't have read many of them. But it is true that most experts in the field would put some of the australopithecines in human ancestry. > That is not because there is strong, direct evidence of such descent but > because the ruling ideology of the life sciences is neoDarwinism and > hence most scientists conform to that interpretation while shunning > contradictory views.

In other words, anyone who disagrees with you is biased. How is that you ignore the opinion of virtually every current expert, and accept uncritically the opinion of Zuckerman and Oxnard? Bias? > >Richard started this off by saying: > > > >>RM "Java Man" is now accepted as having been an extinct ape, and > >> every single claimed "missing link" fossil has been re-assigned > >> either as an extinct ape or as a human essentially the same as > >> modern humans. > > > >Richard may consider that every single claimed "missing link" fossil is an > >ape or a human.

For instance 'Pithecanthropus erectus' is now Homo erectus: > Zinjanthropus is now Australopithecus. 'Peking man' is now Homo erectus and > 'Neanderthal man' is now Homo sapiens. In other words, anything in Homo is human, and anything in Australopithecus is an ape. If we play this sort of word game obviously nothing can be transitional. Richard said in a previous post: "Of course it is true that we must look at the anatomy of the fossils themselves." but that is exactly what he is not doing. He hasn't referenced *anyone* who has looked at anatomy and said H. habilis is human. By the way, many scientists are now putting the robust australopithecines in the genus _Paranthropus_ ("near man"). If Richard's method of classification by name made any sense, Paranthropus must be more human-like than Australopithecus ("southern ape"). It doesn't make any sense because the rules of nomenclature sometimes mean that fossils end up with names that don't reflect current thinking, and it is forbidden to change the names merely to track current opinions. > I have no objection to you surrendering your critical faculties and blindly > following Darwinist scientific "authorities" if you choose to do so, Jim, > but don't be so surprised if some of us decline to follow you without > evidence. > > I am perfectly willing to continue this debate with Jim, but it would be > conducted more efficiently in future if he would produce some specific, > strong, direct, concrete evidence to support his belief in a missing link, > instead of generalisations, opinions and scientific urban myths. Java Man. ER 1470. I've produced plenty of references showing that they are not a gibbon and a modern human respectively. You have yet to produce any credible counter-evidence. Also Louis Leakey's Homo habilis skulls (OH 7, OH 13, OH 16) which you claim are human. I'd like to know by what definition these can be considered "human". Also Peking Man, which we haven't discussed yet. -- Jim Foley Jim.Foley@symbios.com In theory, theory and practice are the same, in practice they're not.  Note also that my definition of 'human' ("a fully modern human with no significant differences from us"), about which Milton is objecting so strenuously, seems virtually identical to his own phrasing of "a human essentially the same as modern humans", which can be found at the top of milton1.html.
