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 ...
Earliest evidence of human (not necessarily anatomically modern humans) presence at Arctic latitudes. [47] Asia, Central Asia, Tibetan Plateau: Tibet, PRC: 38: Salween River: Formerly dated to 15 kya, the date modern human presence in Tibet has been pushed back to at least 38 kya based on genetic evidence.
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.
Fossil footprints show humans in North America more than 21,000 years ago, the earliest firm evidence for humans in the Americas and show people must have arrived here before the last Ice Age.
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).
Mammoth bones and “ghost” footprints of ancient people are the latest evidence in a scientific debate about when the first humans reached the Americas.
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.
This would mean that humans were occupying North America during the Last Glacial Maximum (LGM) – a theory that had previously been dismissed. [25] Though it is not currently the widely-accepted theory, these archaeological sites support alternative theories of early human migration such as a coastal migration route or the Solutrean hypothesis.
