Our son is youngest to be published by Smithsonian 3 times on Native Tribes, cross references to DNA between tribes. He lived in Alaska for 9 years, his Bear trackers were Inuit. He sighted Nomadic tribes, on 2 occasions. Which is so rare, only one tracker had ever witnessed Nomad camp.

While our son is greatly respected with many tribes, Nomads will not allow a non native near their camp. His estimate was about 300 at nightfall. At dawn, everything was gone.
He nor his trackers could find any evidence after 2 miles.

I have his handwritten journals of all Native Alaskan Tribes their Ancestors stories and detailed accounts of roots, bark, and plants used by Shamans, and Healers.

Very interesting. I would guess that it would take a few cycles so to speak of global warming and cooling for various species to cross the land bridge.

It's only been about 10,000 years since the last large migrations across the straits. And people still do it today, both directions. You can walk to Russia in winter, the crossings never ended just slowed way down.

Just taking in mind the very large number of people and animals in North and South America you wonder where they all came from if the origin of life so to speak was in Africa.Introduction to Human Evolution | The Smithsonian Institution's Human Origins Program
