I just was able to get a copy of the Science article on the new find at
Dmanisi. The amazing fact is that the authors are just a whisker away from
saying that these skulls are transitional between H. erectus and H. habilis.
Indeed they do suggest that the habilines were the first to emigrate from
Africa. And that would be an amazing feat for mankind 2 million years ago.
ìWe suggest that the ancestors of the Dmanisi population dispersed from
Africa before the emergence of humans identified broadly with the H. erectus
grade.î Abesalom Veku et al, ìA New Skull of Early Homo from Dmanisi,
Georgia,î Science, 297(2002):85-89, p.85
ìThe Dmanisi hominids are among the most primitive individuals so far
attributed to H. erectus or to any species that is indisputably Homo, and it
can be argued that this population is closely related to Homo habilis (sensu
stricto) as known from Olduvai Gorge in Tanzania, Koobi For a in northern
Kenya and possibly Hadar in Ethipoia. The presence at Dmanisi of individuals
like D2700 calls into question the view that only hominids with brains
equivalent in size to those of mid-Pleistocene H. erectus were able to
migrate from Africa northward through the Levantine corridor into Asia. It
now seems more likely that the first humans to disperse from the African
homeland were similar in grade to H. habilis (sensu stricto).î Abesalom Veku
et al, ìA New Skull of Early Homo from Dmanisi, Georgia,î Science,
297(2002):85-89, p. 88.
Now to Jay's questions:

Fine, then does that mean you believe humanity is over 2.5 million years
old? That is how old the genus Homo is.

Documentation please? I would like to ask why the nasion projection is
different in ancient hominids, why they had flattened rear-protruding skulls
with large brow ridges which we don't see today? Are you actually aware of
the major skull changes between us and them? ARe you aware that these skull
changes don't exist today in any human population? For instance, the H.
erectus, if looked at from the top, has a skull which is hour-glass shaped.
No modern human has that shape of a skull so how can you claim that these
are nothing more than variants within the modern population?
>Assumptions about braincase and other skeletal characteristics of the
>pre-historic hominids are fascinatingly speculative at best.
No, they are observational. I would ask if you have ever read a technical
journal or book on anthropology? If you are so sure of this, please document
>I love scientific inquiry but believe too many scientists tend to make the

Are you another lawyer who, like Phil Johnson, thinks he doesn't have to
actually read the subject matter before critiquing it?
>This condition is endemic to patron, tenure and grant systems requiring

I get no grants, have no tenure (indeed am subject to layoff at a moments
notice) and don't seek certain results. In fact I never intended to become
what I am today. Thus I don't seek certain results.
>Abuses also are engendered by a media thirsty for news.
Agreed, but you paint with a very broad brush. What IN PARTICULAR makes you
think this applies here?
