“A fresh look at the story of our human evolution.”
– this is a fascinating article, not only for what it says, but what it implies: there wasn’t any warfare in our ancient past. Instead, it was the opposite: a whole load of interbreeding.
Several recent studies show conclusively that modern humans, Neanderthals and Denisovans regularly interbred, and that a ghost lineage (maybe H erectus) might have also contributed DNA too.
The two closest relatives of humans are the chimpanzee and the bonobo. Chimpanzees are relatively aggressive and warlike; bonobos are much more peaceful and cooperative. It seems very likely that both kinds of traits existed in the common ancestor of all three species (humans, chimps, bonobos), and after humans hit the savannah, they had no choice but to cooperate or starve.
The writer has two standards of proof: “show conclusively” and “supporting evidence“.
