"This sophisticated hunting behavior..."
Doesn't that kind of describe Grizzly bears and Salmon runs? Are Griz sophisticated?
Unbearably so.
Go where the food is? Inconceivable!
Just spent a few minutes trying to find the carved holes on the net but couldn't find it ~ will need to think of the words for that one first but it first appeared way back in Scientific American before it turned into a rag.
Again, my thesis is the Neanderthals weren't supermen but they were successful at hunting game, particularly reindeer. This depleted the supply available to other invading people of a different variety, and effectively kept them out of Europe. Europe was short serious quantities of food in the last glacial period.
Then, one day the Neanderthals died out ~ a disease possibly ~ maybe the Mother Ship ~ whatever, once they were gone, the game recovered and the Cro-Magnon people could hunt their way into Europe.
