Map of the distribution of the main pre-LGM Aurignacian sites. Map of Magdalenian sites at the transition between the Upper Paleolithic and the Mesolithic. While anatomically modern humans AMH may have been present in West Asia since before ka,  modern non-Africans mainly descend from the main successful out of Africa expansion at around 65 ka. AMH are estimated to have interbred with Neanderthals during about 65 to 47 ka, most likely in West Asia. Neanderthals became extinct shortly after this time, presumably being outcompeted or actively killed by the advancing EEMH.

During the Pleistocene, mountain glaciers formed on all the continents and vast glaciers, in places as much as several thousand feet thick, spread across North America and Eurasia. In the eastern U. The Cenozoic [Recent Life] Era is divided into two main sub-divisions: Most of the Cenozoic is the Tertiary, from 65 million years ago to 1. The Quaternary includes only the last 1.
