The origins of Europe are Upper Paleolithic (South Asian Indian/Iranian/Afghan) and Mediterranean (Near Eastern). The claim is supported by the top left graph, which shows Europeans as intermediates between the two and smoothly blending with them. If we had a better study, we would see that it is Southern Europe that is blending into the Near East, and Eastern Europe that is blending into South Asia.  The results of the study shows what I originally thought to be the case. Europeans are closely related to neighboring Caucasoids and genetic drift occurs within the continents, often to a greater extent than the drift between them. In other words there is no magical line dividing Europeans from other Caucasoids, just gradual drift.

In addition, the Sahara Desert indeed separates North Africans from South Africans.  There is a huge gap.  North Africans represent another part of the Caucasoid cluster, and all Caucasoids do cluster.

Nothing surprises me here, but it’s good to see more evidence.  If you view the bottom graph, I have always held the view that Europe can be divided into the East, the South, and the Northwest. It seems the people who did this study agree with me, as they made such divisions.

While I have held most of the same views before I saw this study, it is good to see them confirmed.
