How did the early people migrate to north America?

Answer 1

Starting at India, the Native Americans traveled north at Asia, crossed the Bering Strait where it was occupied by a bridge during the Age, and traveled south throughout North America.

Answer 2

It is believed that early people migrated to North America over the Bering land bridge, which connected Asia and North America during the last Ice Age. As the glaciers melted, the bridge became submerged, and people continued to migrate further south into North America. This migration is thought to have occurred around 15,000-20,000 years ago.

Answer 3

The main migrations took place in many waves from central and north-eastern Asia during the periods when the Beringia land bridge was free of ice (that is between 32,000 and 36,000 years ago, between 20,000 and 28,000 years ago and around 12,000 years ago).

There are many specific anthropological connections between all natives of the Americas and the ancient people of East Asia, including "shovel incisors", where the inner surfaces of the upper front teeth are concave - among both native Americans and east Asians the incidence of this feature is over 90%; among all other people in the world it is less than 15%.

Answer 4

The distance between Russia and Alaska (at the closest point, 66 degrees north latitude) is less than 85 kilometers (53 miles) and can be crossed by canoe in less than a day, when the ocean is not frozen. There's also an island in the middle. The Arctic ice sheet changes from year to year, but can be crossed on foot at certain times, at the same location (66 degrees north).

Answer 5

Sea levels fell during the Ice Ages, exposing land previously under the seas, including the land bridge joining Asia and South America. Humans had crossed this land bridge into the the Americas by the end of the last glacial period, or more specifically what is known as the late glacial maximum, no earlier than 23,000 years before present.

Answer 6

Antarctica.
