Sequencing of 81 entire human mitochondrial DNAs (mtDNAs) belonging to haplogroups M1 and U6 reveals that these predominantly North African clades arose in southwestern Asia and moved together to Africa about 40,000 to 45,000 years ago. Their arrival temporally overlaps with the event(s) that led to the peopling of Europe by modern humans and was most likely the result of the same change in climate conditions that allowed humans to enter the Levant, opening the way to the colonization of both Europe and North Africa. Thus, the early Upper Palaeolithic population(s) carrying M1 and U6 did not return to Africa along the southern coastal route of the “out of Africa” exit, but from the Mediterranean area; and the North African Dabban and European Aurignacian industries derived from a common Levantine source.
Pretty much agrees with every other conclusion about the colonisation of North Africa I’ve ever seen, although the date is older than a couple. Some of the bickering about the entry dates has ben rendered moot by the Taroralt Mt DNA that shows Eurasian DNA 12,000 years ago in Morrocco. The date has to be very much prior to the Ibero Maurassian though (20,000) because the Eurasian ancestry was in situ in Morocco before the Halfan migration north from the Egypt area spread out across as far as East Morocco and the Levant, and into East Africa. The Logic? The Western IM samples are ‘all Caucasoid’ but the samples from east Morrocco as far as Israel show a mix of Sub Saharan and Eurasian traits. The Eurasian migration had to predate it.
I’d just like to ask how, looking at the distribution pattern of M1a which shows a hot spot in Egypt and has a date predating the expansion into east Africa, it has been labelled as East African in origin. It shows up in Southern Iberia, so the sanest explanation is that it’s NE African in origin and dates back prior to the Hafan expansion that turned into the Kebaran and Ibero-Maurussian cultures.
I’m still searching for the full text of this.
