The fact that these people used so-called Ibero-Maurusian tools , a tool kit that originated in Africa--not Iberia--illustrates the African origin of this group. .[/QUOTE]How is it they used Ibero-Maurusian tools? Were the Ibero-Maurusians a separate people but the Natufians used their tool kit? [/qb][/QUOTE]That is because the Iberomaurusian came from further South. [/qb][/QUOTE]No they didn't [/qb][/QUOTE]Yes, they did. :D [QUOTE] We conducted a comparative analysis of segments between the PP5–6 samples, HP assemblages and more recent archaeological sites through- out Africa. SADBS segment dimensions (Supplementary Table 4) are within the 95% confidence intervals for segments at the MSA and LSA boundary in East Africa, the Tamar Hat Iberomaurusian in North Africa (,20–10kyr), and Holocene assemblages in South and East Africa (Fig. 1). More easily flaked obsidian (owing to its lack of crystalline structure) dominates the East African assemblages, so despite a tougher raw material (silcrete) the SADBS knappers produced comparable microliths. SADBS segments are shorter and thinner than HP segments with no overlap in confidence intervals for width; they are more similar to East African LSA assemblages than the HP (Fig. 1). [/QUOTE]--Kyle S. Brown1,2 et al. An early and enduring advanced technology originating 71,000 years ago in South Africa [QUOTE] Our results also point to a less ancient western sub-Saharan gene flow to Tunisia, including haplogroups L2a and L3b. This conclusion points to an ancient African gene flow to Tunisia before 20,000 BP. [b]These findings parallel the more recent findings of both archaeology and linguistics on the prehistory of Africa. [/b] [...] However, considering the general understanding nowadays that human settlement of the rest of the world emerged from eastern northern Africa less than 50,000 years ago, a better explanation of these haplogroups might be that their frequencies reflect the original modern human population of these parts of Africa as much as or more than intrusions from outside the continent. The ways that gene frequencies may increase or decrease based on adaptive selection, gene flow, and/or social processes is under study and would benefit from the results of studies on autosomal and Y-chromosome markers. Since the end of the extreme Saharan desiccation, lasting from before 25,000 years ago up to about 15,000 years ago, the Sahara has had post- and pre-Holocene cyclical climatic changes (Street and Grove 1976), and corresponding increases and decreases in population are probable. Wetter phases with better habitats perhaps allowed for increased colonization and gene and cultural exchange. Desiccation would have encouraged the emigration and segmentation of popuations, with resultant genetic consequences secondary to drift producing more variation. During the last glacial period, the Sahara was even bigger than it is today, extending south beyond its current boundaries (Ehret 2002). About 13,000 years ago, large parts of the Sahara were as dry as the desert is now (White and Mattingly 2006). The end of the glacial period brought more rain to the Sahara, especially from about 8500 to 6000 BC (Fezzan Project 2006). By around 3400 BC, the monsoon retreated south to approximately where it is today, leading to the gradual desertification of the region (Kröpelin 2008). Thus the Sahara, through its cyclical environmental changes, might be seen as a microevolutionary “processor” and/or “pump” of African people that “ejected” groups to the circum-Saharan regions in times of increasing aridity.[/QUOTE]--Frigi et al.
