Descrizione:
12,000-11,000 years ago… Rapid settlement of first North and then South America (accepted date, but people could've been in the Americas at 50,000 or 40,000 years ago, according to some evidence). People walk from Siberia on Bering land bridge, exposed during that time. Whole of Americas has 10 million hunter-gatherers (?).
Like in Australia/New Guinea, the first human appearance coincides with mass extinction of large mammals: elephants, horses, lions, cheetahs, camels, large ground sloths. Mass extinction leaves humans in the Americas with no large mammals to domesticate, or share disease immunity with.
