This has many implications. These include the following:
* It puts a latest possible date on an Out of Africa migration. This tends to disprove the hypothesis that there was an Out of Africa migration that failed ca. 75,000 years BP followed by a second Out of Africa migration that struck, ca. 50,000 years BP, that has been advanced by many. The recent trend has been to attribute all early evidence (such as Altai Neanderthal DNA showing admixture with modern humans ca. 100,000 years BP and archaeological traces in the Levant, the interior of Arabia and South Asia) of modern humans outside of Africa to a stillborn Out of Africa migration.
* It puts a latest possible date on Denisovan admixture with the ancestors of Australian Aboriginal people who, together with Papuans and Negrito populations from the Philippines have significant levels of Denisovan admixture today.
* It tends to make the megafauna extinction that followed the arrival of modern humans in Australia less immediate with as much as a 20,000 year gap between first contact and the extinction of some Australian megafauna species.
* It puts a latest possible date on behavioral modernity in anatomically modern humans. Almost all of the evidence used to put the start of the Upper Paleolithic era at around 50,000 years ago has subsequently been found more like 70,000 years ago.
