This is not Negroid admixture. Right?

40% SSA in in average N. Africans? That's way too high and doesn't add up with the data provided by G25.

It probably combines all african components on Dodecad.

The African admixture was computed by adding up the Northwest African, East African, Neo African and Paleo African components, which were too minor in Europe on their own. African admixture was found among Neolithic farmers, and especially those from the southern Levant, who assimilated the Mesolitic Natufians (confirmed to belong to Y-haplogroup E1b1b). The Neolithic farmers who carried the most African admixture to Europe were those who followed the southern route via North Africa, then spreading from Spain to western Europe with the Megalithic cultures. Some individuals from the Funnelbeaker culture in Scandinavia, which derives partly from the Atlantic Megalithic, carried as much as 11% of this African admixture. It subsisted at lower frequency in Scandinavia at least until the Late Iron Age. Later, the Phonenician/Carthagenian colonisation, then the Arab conquest of the Iberian peninsula and of Sicily brough additional North African DNA to southern Europe. This admixture is essentially a Northwest African, but contains some Sub-Saharan African too, like in North Africa itself. Note the resemblance with the distribution of Y-DNA haplogroup E-M81.

According to the creator of the admixture map, this African admixture is essentially a Northwest African, but contains some Sub-Saharan African just like in North Africa. Gene-flow from North Africa to three surrounding coastal areas that have been documented to have had historical contact with North Africans: Tuscany, Iberia and the Canary Islands. In the Iberian Peninsula, the inferred date of North African related admixture is from around the eleventh century (1027–1058) to the second half of the fourteenth century (1330–1356).

Figure 3. Globetrotter admixture results for the three geographical regions analysed (Tuscany, Iberia and the Canary Islands). The mean admixture date and confidence intervals for each admixture event are shown above the graphs. The geographical locations of surrogates that contribute more than 2.5% are coloured in the maps, with circle sizes showing the proportion of contribution. Coloured areas boundaries are defined by the genetic clusters' geographical distribution. Each different shade of grey corresponds to a different admixing source group, with the surrogates representing that source group linked via a continuous or dashed line (Arauna et al. 2019).
