Recent genetic contributions to the field of palaeoan- thropology suggest that all modern humans are derived from a common ancestral population living in sub-Sa- haran Africa between 200,000 and 100,000 years ago (Cann, Stoneking, and Wilson 1987, Vigilant et al. 1991, Horai et al. 1995, Quintana-Murci et al. 1999, Ingman et al. 2000). This proposition is supported by early Upper Pleistocene human fossils discovered at sites such as Bor- der Cave and Klasies River Mouth in South Africa (Right- mire 1979, Singer and Wymer 1982) and the Omo Kibish formation in Ethiopia (Butzer, Brown, and Thurber 1969, Day 1972).\n\nThe model of African genesis posits an expansion of modern human populations out of Africa and into west- ern Asia. If there were early Upper Pleistocene human pulses emanating from Africa, the route of dispersal (as- suming that maritime travel directly across the Red Sea was not possible) would have been limited to two con- duits—the Levantine corridor connecting Egypt and the Near East and the Arabian corridor, where the Bab al Mandeb Strait links the Horn of Africa with South Arabia.
