African admixture in Southern Europeans

[Insuperable]

The map is not entirely correct. Croatia and Poland have less or the same amounts of E when compared to Spain and France

To be honest, I think much of this African are possibly remnants of the Mesolithic Europeans, who score about 90% Atlantic-Baltic and 10% East-African. Why it is not found in Northern Europeans might have to do with different refugee populations migrating North, and the founding effect, furthermore, the Northern Europeans have different influences from West Asia and Siberia which may further distance them from Africa in affinity tests.

I'm not sure how much of it is recent. Overall, it should not have much of a phenotypical influence. This is less admixture than an average European has of Neanderthals, and we don't see them walking around.

As you can see the grey data indicated "no data". It means that there was research only for "green" colored countries.
And because of that your post has no point.

That map of Haplogroup E is completely outdated and/or with very little information. There is a lot more of it in Southern Europe.

This map is much better:


This is for E1b only though.

^ On these haplogroup maps, do the circles represent founding populations from which the rest of the population with the haplogroup has spread? It would be interesting if we could connect such regions with historical knowledge of population movement, and to target the source of such haplogroups. For example, the circles in Northern France/Belgium, Galicia, and the Balkans definitely seem like some founding population effect, for which the rest of the frequencies originated in the peripheries of those regions.

It has something to do with that and the peak concentration of it in that area what you are referring to as the "circles". It dissipates as it gets further away from the highest concentrated areas of that haplogroup of course.

You can see trends that make sense historically and autosomally.. Galicia has one of the highest rates of North African genetic influence in Spain, and has the higher frequency of E1b there. E1b is common in Cyprus but not the Levant, which shows the Greek influence, and is most present in Italy along Calabria and the eastern Sicilian coast, which means it came from Greece.

E1b doesn't necessarily contribute to North African genetic influence but mainly Mediterranean from the Mediterranean component in Dodecad.

E1b1b=SouthWestAsian/Red Sea and EastAfrican(SSA) admixture.

Mediterranean=G2a.

Mediterranean=G2a.

Exactly! As I said the (East) Med component was most probably brought in by Neolthic farmers. All researches show that.
