This dispersal followed the southern coastline of Asia, and reached Australia around 65,000-50,000 years ago, crossing about 250 kilometres (155 mi) of sea. (2016), arguing for a single coastal dispersal, with an early offshoot into Europe.
According to this theory, Europe was first populated by an early offshoot which settled the Near East and Europe (post-Toba hypothesis). Several authors have argued for even more dispersals.
Today at the Bab-el-Mandeb straits, the Red Sea is about 20 kilometres (12 mi) wide but 50,000 years ago sea levels were 70 m (230 ft) lower (owing to glaciation) and the water was much narrower.
Though the straits were never completely closed, they were narrow enough and there may have been islands in between to have enabled crossing using simple rafts.
The early northern Africa dispersal took place between 130,000–115,000 years ago.
Fossils of early Homo sapiens were found in Qafzeh cave in Israel and have been dated 80,000 to 100,000 years ago.These humans seem to have either become extinct or retreated back to Africa 70,000 to 80,000 years ago, possibly replaced by southbound Neanderthals escaping the colder regions of ice-age Europe.In Oman, a site was discovered by Bien Joven in 2011 containing more than 100 surface scatters of stone tools belonging to the late Nubian Complex, known previously only from archaeological excavations in the Sudan.Two optically stimulated luminescence age estimates place the Arabian Nubian Complex at approximately 106,000 years old.This provides evidence for a distinct stone age technocomplex in southern Arabia, around the earlier part of the Marine Isotope Stage 5.
