The important discovery of a cro Magnon settlement in the Southernmost Sahara dating to the Holocene brings new data on the morphological and geographical evolution of the Cro Magnon population of the Maghreb (Men of Mechta-Afalou-Taforalt). The great resemblance between the men of Taforalt and those of the Sahara (Hassi-el-Abiod, Mali) pose the problem of their origins. Was it a migration from the Maghreb at the beginning of the Holocence aided by favourable climate conditions or regional evolution from the regional Aterien stock mixing with the Cro Magnons of the Maghreb and the Sahara? The numerous climatic changes occurring in this part of the Sahara during the last 30,000 years could be an efficient evolutive promoter and can explain the morpholgical and cultural differences observed between the Sahara and Maghrebian series. However, what will happen later to African Cro magnids in the Maghreb and especially in the Sahara is still an open question.
I’m not going to translate the whole thing, but it observes that the Mechtoids vanish about 7,0oo years ago (very latest site in the Sahara, but they are gone by 10,000 Bp at the coast when the Capsian culture arrives from the near east) when the proto- mediterranoids arrive, and they are not found in later sites. When I have a little more time I’ll make up a more comprehensive entry involving this and the other work on mechtoid populations and genetics that should explain their origins and relationships a bit more clearly. Please excuse my imperfect translation.
These new discoveries bring three new basic concepts; firstly, African Cro Magnids occupied a vast part of the North of Africa of the end of Pleistocene until the beginning of the Holocene; secondly in spite of regional morphological characteristics, all Mechtoids belong to the same group; thirdly these facts suggest the existence of a common ancestor to these three populations and this ancestor could be represented, until there are other older discoveries, by the Aterian people.
Which I’d have to disagree with, as the stone tool cultures and genetics suggest an expansion from Lower Nubia/Egypt about 24k ago that spawned off the Mechtoid/Kebaran populations, which was roughly equal in terms of back-migrating Eurasian and Nubian-African ancestry. Except for the Taforalt population, which ADNA has shown was entirely Eurasian for mt DNA, and may have been the result of a migration southwards across the straits of Gibraltar about the time of the LGM (20k ago) mixing with the local Mechtoids.
