According to co-author Ilan Gronau, "This actually complements archaeological evidence of the presence of early modern humans out of Africa around and before 100 ka by providing the first genetic evidence of such populations." The date most commonly attributed to the remains is 67,000 BP.
High rates of variability yielded by various dating techniques carried out by different researchers place the most widely accepted range of dates with 67,000 BP as a minimum, but does not rule out dates as old as 159,000 BP.
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.
The hypothesized departure of humankind from Africa to colonise the rest of the world involved them crossing the Straits of Bab el Mandab in the southern Red Sea and moving along the green coastlines around Arabia and thence to the rest of Eurasia.
This provides evidence for a distinct stone age technocomplex in southern Arabia, around the earlier part of the Marine Isotope Stage 5.
Fossils of early Homo sapiens were found in Qafzeh cave in Israel and have been dated 80,000 to 100,000 years ago.
Wells (2003) argued for the route along the southern coastline of Asia, across about 250 kilometres (155 mi), reaching Australia by around 50,000 years ago.
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.
