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 ...
Reconstruction of early Homo sapiens from Jebel Irhoud, Morocco c. 315 000 years BP. Early modern human (EMH), or anatomically modern human (AMH), [1] are terms used to distinguish Homo sapiens (sometimes Homo sapiens sapiens) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species (of which some are at times also identified ...

The History of North America encompasses the past developments of people populating the continent of North America. While it was commonly accepted that the continent first became inhabited by humans when individuals migrated across the Bering Sea 40,000 to 17,000 years ago, [ 1 ] more recent discoveries may have pushed those estimates back at ...
In 1972, fragmentary fossils of anatomically modern humans were found at Chouqu and Gangzilin, in Zuojhen District, Tainan, in fossil beds exposed by erosion of the Cailiao River. Though some of the fragments are believed to be more recent, three cranial fragments and a molar tooth have been dated as between 20,000 and 30,000 years old.
Early modern human expansion in sub-Saharan Africa appears to have contributed to the end of late Acheulean industries at about 130,000 years ago, although very late coexistence of archaic and early modern humans, until as late as 12,000 years ago, has been argued for West Africa in particular.

David Bustos heard about the “ghost tracks” when he first went to White Sands National Park in New Mexico to work as a wildlife scientist in 2005.
They divided the archaeological record in the Americas into five phases, only three of which applied to North America. [1] The use of these divisions has diminished in most of North America due to the development of local classifications with more elaborate breakdowns of times. [2] 1. The Paleo-Indians stage and/or Lithic stage 2. The Archaic ...
