I guess it depends on your definition of civilization. The field genetics is finding some fascinating stuff. This out of Africa migration theory points to a migration some 100,000 years ago where a large number of migrants diverged east and west somewhere around Israel. Those who went east traveled across Asia and into the Americas. Those who went west settled Europe. Those people didn’t meet again until Columbus discovered the New World.
I don’t understand the big deal here. Battlestar Galactica (reboot) explains everything. Just watch it as a documentary. :)
