I suppose, then, that the natives at the source of the Nile were a subspecies (or a separate one altogether) of those that lived at the mouth of the Nile 3000 years ago?
Do you believe it possible that tools/artifacts/art/food/customs/etc. are subjected to modern ethnocentric prejudices?
However, one thing that is now much, much clearer that it was just a decade ago is that Neanderthal and Cro-Magnon behavior was far more different than had been thought the case. The Neanderthal had inferior tools, inferior weapons, inferior artistry, etc.
So, if it were a full sentence, it would be: The Neanderthal had inferior tools, inferior weapons, inferior artistry, etc. than what had been thought the case just a decade ago.
I don't see what the problem is with that observation. It's true.
As for ethnocentric prejudice (or even speciescentric prejudice as the case may be) I suppose there could be some of that, but when the Cro-Magnon had cave painting and clay sculpture whereas the Neanderthals are not known to have painted or sculpted anything, that is a rather objective measurement of inferior artistry.
PS. And you'd think I'd correct my typo in that excerpt the second time around! :)
