Latest Models of migration to the New World Stories
Artifacts found in Oregon have once again stirred up the debate surrounding the earliest Americans and how they came to live in the Western Hemisphere.
Scientists have found that Native American populations — from Canada to the southern tip of Chile — arose from at least three migrations, with the majority descended entirely from a single group of First American migrants that crossed over through Beringia, a land bridge between Asia and America that existed during the ice ages, more than 15,000 years ago.
A new study of lake sediment cores from Sanak Island in the western Gulf of Alaska suggests that deglaciation there from the last Ice Age took place as much as 1,500 to 2,000 years earlier than previously thought.
Researchers at Brown University and Stanford University have pieced together ancient human migration in North and South America.
Scientists have uncovered ancient stone tools and thousands of other artifacts dating back 15,500 years at an archaeological dig in Texas, suggesting that humans settled the continent 2,500 years earlier than previously believed.
Evidence for a diversified sea-based economy among North American inhabitants is emerging from three sites on California's Channel Islands.
Researchers say that a scientific reconstruction of one of the oldest sets of human remains found in the Americas supports theories that the first people who came to the hemisphere migrated from a broader area than once thought.
The initial peopling of North America from Asia occurred approximately 15,000-18,000 years ago, however estimations of the genetic diversity of the first settlers have remained inaccurate.
Earliest known human settlement in the Americas raises new questions...
By Sandi Doughton SEATTLE - Hold the potty humor, please, but archaeologists digging in a dusty cave in Oregon have unearthed fossilized feces that appear to be the oldest biological evidence of humans in North America. The ancient poop dates back 14,300 years.
