Thanks Notforprophet.
The “invaders” from the refugia were probably much more numerous than the few who would have stuck out the sub-Arctic conditions up near the glaciers.
Maybe they were all of the people who were displaced from the continental shelf when the seas actually did rise.
She suggests that the Magdalenians, whose artifacts are found along western North Africa as well as the Iberian peninsula, are in fact the remnants of Plato's Atlantic kingdom.
By examining and comparing artifacts from different eras across North Africa and into Southwest Asia, Settegast is able to draw a broad but convincing outline of the movements of peoples throughout the region. Her investigations show that around 9,000 BCE... abruptly, skulls of a different shape (the Gracile Proto-Mediterranean type), which have the bottom incisors knocked out, show up in gravesites. Removal of the bottom two incisors was a ritual common to North African and Saharan peoples, and is still prevalent among Nilo-Saharan groups such as the Nuer and Dinka. Across North Africa and into Southwest Asia at this time, "tanged-point" arrowheads start to appear in great numbers. These factors coincide with a sudden prevalence of running figures with bows in the rock paintings throughout the region. A final piece of the puzzle is the presence of layers of burned material at numerous sites across North Africa and southward up the Nile. Put all this evidence together, and it seems clear that some sort of widespread conflict was going on at this time period, which could very well relate to Plato's war.
