Asian migration to north america

There is plenty of evidence to suggest that humans migrated to the North American continent via Beringia, a land mass that once bridged the sea between what is now Siberia and Alaska. Two new DNA studies sourced from rare fossils on both sides of the Bering Strait help write new chapters in the stories of these prehistoric peoples. The first study delves into the genetics of North American peoples, the Paleo-Eskimos some of the earliest people to populate the Arctic and their descendants. Beringia had formed by about 34, years ago, and the first mammoth-hunting humans crossed it more than 15, years ago and perhaps far earlier. A later, major migration some 5, years ago by people known as Paleo-Eskimos spread out across many regions of the American Arctic and Greenland.

Settlement of the Americas - Wikipedia

Nearly 11, years ago, a man died in what is now Nevada. Wrapped in a rabbit-skin blanket and reed mats, he was buried in a place called Spirit Cave. Now scientists have recovered and analyzed his DNA, along with that of 70 other ancient people whose remains were discovered throughout the Americas. The findings lend astonishing detail to a story once lost to prehistory: how and when humans spread across the Western Hemisphere.

Ancient DNA Reveals Complex Story of Human Migration Between Siberia and North America

The mastodon was old, its teeth worn to nubs. It was perfect prey for a band of hunters, wielding spears tipped with needle-sharp points made from bone. Sensing an easy target, they closed in for the kill. Almost 14, years later, there is no way to tell how many hits it took to bring the beast to the ground near the coast of present-day Washington state. But at least one struck home, plunging through hide, fat and flesh to lodge in the mastodon's rib.

A genetic analysis of a baby's remains dating back 11, years suggests that a previously unknown human population was among the first to settle in the Americas. Scientists recovered the DNA from an infant — only a few weeks old when she died — buried at the Upward Sun River archaeological site in the interior of Alaska. Their data indicated that the baby belonged to a group of people who were genetically distinct from humans in northeastern Asia, the region that launched a migration into North America over a now-submerged land bridge across the Bering Strait.
