[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by Cass/: [qb] @ Oshun SSA is not a valid biological construct, but the entire African continent is? Got to love these pan-Africanist loons. Your whole agenda from day 1 since being here has been to stop people differentiating North Africans from populations below the Sahara as part of your pan-African politics, hence also why you politicalize the word "black" to cover the whole continent. Anyway, if you look at the Koppen climate map, the vast majority of SSA is humid-heat: blue and green shades on map: [IMG]https://upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Africa_map_of_K%C3%B6ppen_climate_classification.svg/120px-Africa_map_of_K%C3%B6ppen_climate_classification.svg.png[/IMG] ~ That is more or less the "Negroid" or "Broad African" geographical zone in Coon (1962), Baker (1974), Hiernaux (1975) etc. [/qb][/QUOTE]It's just incredible how this eurocentrick imbecile keeps posting this eugenic piece of **** C.Coon. As if this is a supposed reliable source. That map contradicts you once again. lol smh [QUOTE] [b]"Climate-Controlled Holocene Occupation in the Sahara: Motor of Africa's Evolution"[/b] "Radiocarbon data from 150 archaeological excavations in the now hyper-arid Eastern Sahara of Egypt, Sudan, Libya, and Chad reveal close links between climatic variations and prehistoric occupation during the past 12,000 years. Synoptic multiple-indicator views for major time slices demonstrate the transition from initial settlement after the sudden onset of humid conditions at 8500 B.C.E. to the exodus resulting from gradual desiccation since 5300 B.C.E. Southward shifting of the desert margin helped trigger the emergence of pharaonic civilization along the Nile, influenced the spread of pastoralism throughout the continent, and affects sub-Saharan Africa to the present day."[/QUOTE]—Kuper R1, Kröpelin S. Science. 2006 Aug 11;313(5788):803-7. Epub 2006 Jul 20. Climate-controlled Holocene occupation in the Sahara: motor of Africa's evolution. http://www.ncbi.nlm.nih.gov/pubmed/16857900 [QUOTE] Desiccation of the Sahara since the middle Holocene has eradicated all but a few natural archives recording its transition from a "green Sahara" to the present hyperarid desert. Our continuous 6000-year paleoenvironmental reconstruction from northern Chad shows progressive drying of the regional terrestrial ecosystem in response to weakening insolation forcing of the African monsoon and abrupt hydrological change in the local aquatic ecosystem controlled by site-specific thresholds. Strong reductions in tropical trees and then Sahelian grassland cover allowed large-scale dust mobilization from 4300 calendar years before the present (cal yr B.P.). Today's desert ecosystem and regional wind regime were established around 2700 cal yr B.P. This gradual rather than abrupt termination of the African Humid Period in the eastern Sahara suggests a relatively weak biogeophysical feedback on climate. [/QUOTE]—Kröpelin S et al.
