I did not think that there was a "Erectus Robustus" but I did not know
that it had been "proved".

Actually, that is my arguement against "parallel development", i.e. if the
robust Neanderthal-like physiology did not develop independently in a
H. Erectus population in Asia in response to similar environmental pressure,
why should we suppose separate but parallel evolution towards modern
man! Northern Siberia had an environment at least as rugged as Europe
during the Ice Ages, but did not develop an Asiatic Neanderthal (as
best as I can tell!).
At the same time, the Neanderthals and their Erectus contemporaries
settled into an apparently little changing life style and society for
several hundred thousand years, only to completely be supplanted by
a rocket-like parallel evolution to modern man? Dont think so boss!

I guess that I am really thinking of the "absorption" theory, ie
that the local Neanderthal and Erectus populations may just have
merged with the more modern man that was streaming out of Africa.
Sort of like the Roman, Hun and even Mongol occupations of Europe.

I thought that there were also some 30k Neanderthals discovered in
Bosnia, Croatia or Macedonia in what used to be Yugoslavia.

I'll drop in for a peek. Thanks much.
