The genetic type of the From Africa scenario gets more complicated. There might be two waves, along with the probability of admixture between your Neo-Africans and archaic hominins, such the Neandertals and Denisovans. From things i can gather the genetic evidence has become converging upon the succession of occasions where African populations diverge >100,000 years back (e.g., an in-depth separation between your forefathers from the Bushmen and also the forefathers of West Africans), along with a radiation of non-Africans for the most part ~75,000 years back, and much more likely ~50,000 years back. You will find still many holes to become blocked in. In the end re waiting on genetics, here s a fascinating paper using historical techniques in PLoS ONE, The Nubian Complex of Dhofar, Oman: An African Middle Stone Age Industry in Southern Arabia:
Regardless of the numerous studies suggesting early population expansions from Africa into Arabia throughout the Late Pleistocene, no historical sites have yet been discovered in Arabia that look like a specific African industry, which may indicate demographic exchange over the Red-colored Ocean. Ideas report the invention of the hidden site and most 100 new surface scatters within the Dhofar region of Oman owned by a regionally-specific African lithic industry the late Nubian Complex known formerly only in the northeast and Horn of Africa throughout Marine Isotope Stage 5, ~128,000 to 74,000 years back. Two optically stimulated luminescence age estimations in the open-air site of Aybut Al Auwal in Oman put the Arabian Nubian Complex at ~106,000 years back, supplying historical evidence for the existence of a definite northeast African Middle Stone Age technocomplex in southern Arabia between the very first 1 / 2 of Marine Isotope Stage 5
