[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by Djehuti: [b]It used to be thought that the Halfan Culture of the Nile Valley was the progenitor or Oranian (Ibero-maurusian) Culture of the Maghreb but the earliest Oranian sites predate the Halfan culture by several millennia[/b]. Though I do recall some sites in the coastal Cyrenaica area of Libya (Dabban Culture?) which may hold potential being the true progenitors of the Oranian and thus be the missing link between the Maghreb and the Nile Valley. That is something I'll have to look up unless Swenet has some answers to that. [/QUOTE]The oldest radiocarbon date of the Halfan (25ky, IIRC) rivals the oldest date of similar industries in the Maghreb. Although this date is usually rejected because the other Halfan dates are much younger. However, I think eventually they will find LSA industries in the Maghreb that are older than anything similar in the Nile Valley, including that one 25ky Halfan date. This is because North African LSA populations had the Maghreb more or less to themselves after the Aterian declined 40ky ago, while Aterian-like NAMSA populations were still dominant in the Nile Valley. As you know, NAMSA (North African MSA) populations older than mtDNA Eve descended humans lived in North Africa first. Mixture with these older NAMSA populations is IMO partly why LSA North Africans generally have that unique ('Mechtoid') look. I think LSA North Africans lived in some refugium in the Red Sea coast or in the eastern parts of the coastal North African Mediterranean refugia depicted in [URL=https://www.esd.ornl.gov/projects/gen/NEW_MAPS/africa1.gif]Tyrannohotep's LGM maps[/URL]. Haua Fteah and the wider Jebel Akhdar region as you suggested seem good candidates. From there I think they expanded towards the Nile Valley and the Maghreb in several waves and mixed with local populations in both regions. I think most later North African LSA industries spread with these people. I think we just haven't found those refugia yet. But the fact that ancestors of later dynastic Nile Valley populations appear suddenly in the Nile Valley seemingly out of nowhere, not once, but several times, suggests to me those refugia will be found eventually. Just a matter of time. But the Maghreb is a dead end geographically. No population can originate there without migration from population centers north, south or east. It would be weird to me if the ancestor of later North African backed bladelet industries originated there. So I agree with your assessment of looking for an origin further east. [/QB][/QUOTE]
