“…An ancient maximum lake level was assumed to exist 120 m above the current lake level. Based on Lamb et al (2007), we can conclude that such a lake should be at least dated to 15,000 BP. Plotting this assumed level on an ASTER DEM, however, revealed that the present basin cannot support such a high lake level, as the lake would overflow at several locations.…”

“…This northern route by no means offered a permanently open or easy pathway of dispersal. Moreover, the Nile appears to have had a much reduced flow of water intermittently during the Pleistocene, notably during the earlier part of the Pleistocene and during the last glacial maximum (Lamb et al, 2007). Nevertheless, by convention this northern route, whether via the Nile and the Mediterranean coast, or more directly between the Red Sea coast and the Jordan Valley via the Gulf of Suez and the shores of the Gulf of Aqaba, has been assumed to be the principal artery of contact between Africa and western Asia, an assumption reinforced by the abundant finds of Paleolithic archeology and African species of mammalian fauna in the Levant and early dates in the 1.8-1.4 Mya range at sites such as Ubeidiyah (Tchernov, 1992;Ron and Levi, 2001), and further north, in the Caucasus, at Dmanisi at 1.7 Mya (Lordkipanidze et al, 2000).…”

“…Some model simulations of northern hemisphere climatic changes associated with HS-1 indicate a southward drift of up to 10 latitudinal degrees (2). Most of northern Africa became unusually dry around 17-16 thousand calendar years ago (ka) during the HS-1 ice-rafting peak of Heinrich Event 1 (H1), including the Sahara and Sahel (5), Ethiopia (6), and the Red Sea region (7), as did most of southern Asia (8)(9)(10)(11)Figs. 1 and 2).…”
