In follow-up to an earlier post suggesting genetic matriarch Asnat likely carried and bequeathed to Bnei Israel a Eurasian-linked North African mtDNA haplogroup as opposed to a Native African mtDNA haplogroup, several studies report that prehistoric North Africans were Caucasoid. North African facial features written in ancient stone support this finding of an ancient Caucasoid type inhabiting North Africa.
The presence of a Caucasoid type in ancient North Africa supports a significant genetic link of this African region with non-African haplogroups, possibly with those haplogroups which back-migrated from Europe into North Africa in the remote past (U5, for example).
There are four major craniofacial types (used to classify skulls by scientific anthropology) existing among modern humans today - they are Australoid, Caucasoid, Mongoloid and Negroid. Wiki tells us that the Caucasoid type refers to
some or all of the populations of Europe, North Africa, the Horn of Africa, Western Asia (the Middle East), Central Asia and South Asia. Historically, the term has been used to describe many peoples from these regions, without regard necessarily to skin tone.
The word Caucasian refers to the mountains of eastern Europe and to the peoples that are native to this area. This region lies at the border of Europe and Asia, and is situated between the Black and the Caspian sea. It is home to the Caucasus Mountains. The point of all this is to support that Hebrew matriarch Asnat likely carried a mitochondrial genetic haplogroup which originated in Europe, Asia or the Middle East (as opposed to one native to Africa).
