USA HISTORY

Detailed explanation-1: -The First Amerindian Natives are postulated to have come from Asia through the Bering land bridge between 30, 000–12, 000 years before the present (BP). These conclusions have been based on cultural, morphological and genetic similarities between American and Asian populations.

Detailed explanation-2: -Previous genetic work had suggested the ancestors of Native Americans split from Siberians and East Asians about 25, 000 years ago, perhaps when they entered the now mostly drowned landmass of Beringia, which bridged the Russian Far East and North America.

Detailed explanation-3: -Most researchers think Native American roots lie in Asia, although exactly where is not clear; but a few have suggested Europe, a decidedly minority view because today’s Native Americans have clear Asian ancestry. It turns out that both may be right, according to the latest ancient DNA evidence.

Detailed explanation-4: -The ancestors of the American Indians were nomadic hunters of northeast Asia who migrated over the Bering Strait land bridge into North America probably during the last glacial period (11, 500–30, 000 years ago).
