The results do not look so much different from the results of modern North Africans or am I mistaken? Maybe more sub-Saharan?

Compared to modern north africans these copper age north africans had no steppe ancestry and had way more natufian/middle eastern ancestry probably explained by capsian influence

How? Capsians were descendants of Iberomaurusians they were the natives of Maghreb.

The reason this 4,500 year old sample has more levant related ancestry is because Natufian like pastoralists from North East Africa and Levant brought that ancestry there. It's where todays main North African lineage, E-M81, comes from, directly from Natufian related people.

How would you explain an individual like that in the middle of the Iberian peninsula in the Chalcolithic?

Contact between populations on both sides of the strait in ancient times? A casual outlier?

Not at all Capsians had totally different features and culture. According to anthropologists they were proto-mediterraneans and show high similarity to natufians. Not a coincidence if their culture was mostly found in southern tunisia while iberomaurusians were spread all over the maghreb so these pastoralists you're talking about were in fact capsians and I don't buy your theory about E-m81 I already showed you that it's linked to IBM not natufians.

Probably a trader, we find a similar individual during the same era in sardinia :

The most surprising is Sardinia_Chalcolithic15940 from the site of Anghelu Ruju, for whom we obtained a radiocarbon date of 2345– 2146 cal. bc from the same bone sample that we analysed for DNA. We modelled this individual as 22.7±2.4% Anatolia_Neolithic and 77.3±2.4% Morocco_EN (P=0.321). This individual is similar in ancestry composition to the approximately contemporary Iberian individual I4246 from the site of Camino de las Yeseras, radiocarbon dated to 2473–2030 cal. bc, who also had North-African related ancestry as well as the same mtDNA haplogroup M1a1b1 and Y-chromosome haplogroup E1b1b1, which are both typical of North Africans25 (Supplementary Table 14). The finding of African to-European gene flow in both individuals shows that such movement was widespread across the Mediterranean long before the classical period when such gene flow became intensive and the ancestries had a larger demographic impact.

The new study about etruscans also showed north african ancestry there but that was during the iron age.

“Anatomically, Capsian populations were modern Homo sapiens, traditionally classed into two variegate types: Proto-Mediterranean and Mechta-Afalou on the basis of cranial morphology. Some have argued that they were immigrants from the east (Natufians),[10] whereas others argue for population continuity based on physical skeletal characteristics and other criteria.“


They were probably a mixture of early arrivals from the Levant and IBM. E-M81 is directly downstream from Natufian E lol. Show me one IBM sample that had this clade.

I got these informations directly from forensic papers and books while I suppose this quote you posted comes from wiki anyway the purest type shows no similarities with mechta-afalou according to specialists like Gabriel Camps in contrast to IBM they were less robust, had a more "harmonious" cephalic index, were dolichocephal with square orbits, nose structure was more lepthorrhine and angle of the jaw is not "outwards" (I tried to translate his claims as best as I could). He concludes that they share strong similarities with natufians and their expansion from East to West is a good indication of their origin. The datas also show that indeed many were mixed and show strong afalou affinities but they do not form the majority and are probably assimilated elements.

The difference is quite obvious visually :



the first is capsian while the other two are of the mechta-el arbi type

Here again the first is capsian while the other two are of the IBM type :




Proto-mediterranean capsian :



Mechta-Afalou :




And no what Modern north Africans have are direct downstreams of what IAM had :

IAM is early Neolithic though right? It’s after the migrations. Same people who brought that proto-med phenotype brought E-L19.

I just can’t believe that a E-M81 isn’t of Natufian origin. It’s directly downstream Natufian E. I’m not saying anything for sure though.

And that first Iberomaursian is robust as hell. He is on Oberkassel level.
