Nothingness has made the claim, and others have accepted as fact that a reconstrcution of Nebraska Man was made from the evidince of a single tooth.
This is untrue. No such reconstruction was ever made. The claim was based on an article in the "Illustrated London News" in 1922 (can't remember the exact date). The Illustrated London News was a popular magazine/newspaper (rather more respectable than the National Enquirer though). A quote from the article shows this (the information was repeated in both the picture caption and the body of the text):
quote: My emphasis, but note the stress on the speculative nature of the information, and this in a popular paper, not the scientific press. The picture is actually more based on the better known Java Man. It is worth noting that the scientific establishment decryied the production of this drawing as being overly speculative, despite the clear caveats. On the claim that Nebraska Man was accepted in the scientific literature, note this:
quote: Even at the time Nebraska Man was not generally accepted, and shortly after the publication of the above book was found, by later discoveries to be an error. Note, an error, not a fraud. All quotes from the Talk Origins page on the subject. For Whigs admit no force but argument.

I think NOTHINGNESS is talking about the Homo heidelbergensis specmin found at Boxgrove in Sussex, UK, which is sometimes called Boxgrove Man.
See the University College London site on the excavation project. However, the question arises: what problem does NOTHINGNESS see with such a thoroughly researched site? For Whigs admit no force but argument.

NOTHINGNESS
quote: Lucy's knee was NOT found at a distance from the rest of the skeleton. The knee in question is a different fossil from the same (or very similar) species. The bones from Lucy were all found at a single location and, as can be seen, there are no knees:
This myth, which has been circulating in creationists circles for ages derives from a lecture given by Lucy's discoverer Donald Johanson and the University of Missouri, where, in the question and answer session the following happened: Q. How far away from Lucy did you find the knee?A. Sixty to seventy meters lower in the strata and two to three kilometers away. Perhaps the questioner meant Lucy's knee, perhaps not, but Johanson clearly though it meant earlier (1973 as opposed to 1974) find, and answered accordingly. Johansons' knee (AL129):
for a fuller account see here. This knee is almost as important as Lucy herself, since it was the first clear evidence for bipedalism. I've read the popular account of the finds, and the discoverer's awe at what the find signifies comes over very clearly. Edited to add picture of knee.

quote: That Lucy, and indeed all of the Australophicenes, were bipedal is not in doubt any longer. That they were not as capable bipeds as Homo is also not doubted. The were not obligate terrestial bipeds, but udoubtedly spent much time in trees. They were (cue fanfare) intermediate or transitional types. Compare the pelvic structures:
The souce discusses it in more detail, but from the drawings, the intermediate nature is obvious. I will note that the Australopithecene pelis as the slightly later africanus, but afarensis is similar.
quote: Yes we can. We're not just reliant on the knee and Lucy. We've got other fossils as well. There are three main indicators of bipedalism: The knee joint structure where aferensis' knee is almost identical in structure to homo. The pelvis and thigh bone, where aferensis' pelvis is transitional, but fit for bipedalism. The foramen magnum, which is the hole in the skull where the spinal chord enters. For most quadrupeds, its at the back of the skull, for knuckle walkers, about 45deg down, for bipeds, at the base. All Austalopiecenes shows the latter pattern, although, again, sometimes (for earlier fossils) in an intermediate form. The pattern is clear, particularly when you "lay out" the specimins in date order. Finally
quote: There are no disputed claims about Lucy, except in the minds of creationists, many of whom never read anything except creationsist material for fear of being confused by facts. For Whigs admit no force but argument.

quote: The pelvis, the leg bones, the arm bones. Look at the picture of Lucy, and the drawings of the pelvis of P.Troglodytes and H. Sapiens. To which are they closer? What he meant by "before assembling" was after collecting all the bones, but before laying them out in order. To someone with his experience, he could have created a mental picture of the skeleton. Remember, we now have more fossils. The knee alone (discovered a year earlier) proves the existance of a bipedal species even if Lucy is proven not to be bipedal, and thus is removed from A Aferensis.
quote: Is the best you can do 25-35 year quotes from the popular press? There have been huge advances in that time. Yes, there are arguments about the details, but the broad sweep is clear.
quote: Yes, there are arguments about the status of H. habilis. Basically there are three opinions: H. habilis is a valid species. This is the majority opinion. Some of the specimins at either end should go to Australopithecus, and some to H. erectus. Note this would still leave H. habilis standing, as the type specimin is considered valid by this group. H. habilis is a construct, and the specimins should all be reallocated. This is an extreme minority view, largely held by cladists, who don't accept speciation without separation. However, remember this is a reclassification, even in the extreme case. None of the H. habilis fossils are being discarded as potential ancestors of H. sapiens. It's an argument about what we call them. For Whigs admit no force but argument.

quote: The last resort: the "Grand Conspiracy" - everyone is lying to us. However, I did not ask you to look at the africanus pelvis, but to compare Lucy's pelvis with troglodytes and sapiens. Are you seriously saying that you think someone could get away with faking a chimpanzee or human pelvis drawing. To enlighten you: Lucy
troglodytes, africanus and sapiens pelvis
Which one (allowing for symmetry) is Lucy nearest in form? Clearly Sapiens. Given all the other evidence, Lucy was bipedal: probabally not as good as sapiens and certainly not an obligate biped, but bipedal.
quote: Yes.
quote: Oxnard views's have been discredited. He only worked with a few bones in poor condition. Later, more comprehensive studies, have confirmed Australopithecus' bipedal status, as had been believed from the start. See here. However, Oxnard does not support your view. He believes, and always has done, that Australopithecus is in the human family: he simply believes that the differences are such that they cannot be in the direct line.
quote: We've got several knee fossils now, as well as hands and feet. The knee is very close to sapiens, the hands and feet are intermediate, but nearer sapiens. Have you considered the implications for creationism of such a result. As I have already stated, other fossil afarensis include the knee, and can thus be demonstrated to be bipedal. If Lucy was of another, closely related non-bipedal species, we've got our link between the apes and man.
quote: Why bring in monkeys? I presume you mean chimpanzees here. You are demonstrating your ignorance: chimpanzees are not monkeys. And Australopithecus moves like Australopithecus: more like man thanchimpanzee. You could say that some animals do have a limited upright ability...[/quote] Some more limited than others: in a clear spectrum of capabilities from the Last Common Ancester through Australopithecus to sapiens. It is entirely possible that this Last Common Ancester was more bipedal than current chimpanzees.
quote: Why? We don't, and are full obligate bipeds. For Whigs admit no force but argument.

NOTHINGNESS,
You have made this claim:
quote: Unlike many other creationist's claims, this can easilly be tested. Examine the geologic record. If your claim is true, Chimpanzees, monkeys and man should be found fossilised in at least a representative sample of every strata from the Pre-Cambrian upwards to the present. Are they? If not, and they are not why? Edited to correct spelling. This message has been edited by MarkAustin, 08-19-2004 01:48 PM For Whigs admit no force but argument.
