Examples of Clovis and other Paleoindian point forms, markers of archaeological cultures in North America. The Solutrean hypothesis on the peopling of the Americas is the claim that the earliest human migration to the Americas began from Europe during the Solutrean Period, with Europeans traveling along pack ice in the Atlantic Ocean.
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
Archaeologists are piecing together evidence that the earliest human settlements in North America were thousands of years before the appearance of the current Paleo-Indian time frame (before the late glacial maximum 20,000-plus years ago). [51] Evidence indicates that people were living as far east as Beringia before 30,000 BCE (32,000 BP).
One of the earliest identifiable cultures was the Clovis culture, with sites dating from some 13,000 years ago. [20] However, older sites dating back to 20,000 years ago have been claimed. Some genetic studies estimate the colonization of the Americas dates from between 40,000 and 13,000 years ago. [ 21 ]
It’s believed that humans first settled in North America about 14,000 years ago, but a study suggests our kind arrived on the continent some years earlier.
Head lice have been constant, if unwanted, human companions. The parasites are rich sources of genetic information illuminating big questions in the human story.
Using the atlatl, these ancient Paleo-Indians were able to traverse much of the Americas from Alaska, down to Mexico, Central America, South America, and, finally, all the way south into Chile as they hunted and followed these Pleistocene megafauna within a short 3,000 year time period–from about 14,500 years ago to about 11,500 years ago.

Tiny artifacts unearthed at a Wyoming site where a mammoth was butchered 13,000 years ago are revealing intriguing details about how the earliest Americans survived the last ice age.
