[QUOTE]Originally posted by Brada-Anansi: [QB] Guys check-out Charlie Bass's new post on the new new study by Tishkoff and Laura Scheinfeldt [b]Neolithic in Northern Africa[/b] Approximately 14 kya, climatic changes associated with the end of the Last Glacial Maximum resulted in regions around the world becoming more favorable to human exploitation. Northern Africa is one such region, and ~13 kya, novel technologies (“Natufian”) thought to be the immediate precursor to agricultural technologies emerged and were associated with semisedentary subsistence and population expansions in northeastern Africa (35). Moreover, before the emergence of the Natufian styled artifacts, the archaeological record includes two artifact styles, the “Geometric Kebaran” and the “Mushabian” associated with Middle Eastern and Northern African populations, respectively (35). The archaeological evidence suggests the peoples using these assemblages interacted for well over 1,000 years, and linguistic evidence suggests that the peoples using these assemblages may have spoken some form of proto-Afroasiatic (35, 36). Although the origins of the Afroasiatic language family remain contentious, linguistic data generally support a model in which the Afroasiatic language family arose in Northern Africa >10 kya (36). Moreover, analyses of the Cushitic branch of the Afroasiatic language family suggest that proto-Cushitic arose and diversified at least 7 kya, and this likely took place in Ethiopia http://egyptsearchreloaded.proboards.com/index.cgi?board=bag&action=display&thread=565 Much more to read click here^ [/QB][/QUOTE]
