[6] The Capsian diet included a wide variety of animals, ranging from aurochs and hartebeest to hares and snails; there is little evidence concerning plants eaten.

Anatomically, Capsian populations were modern Homo sapiens, traditionally classed into two variegate types: Proto-Mediterranean and Mechta-Afalou on the basis of cranial morphology and anthropological traits.

[12][7][13] In 1950, 3 skulls from the Upper Capsian of the Maghreb were measured, and based on indicators of the craniofacial form, considered to have been mixed in traits.

It was suggested that this population was the product of Pre-Neolithic Mectha-Afalous, "White" immigrants from the east, and African migrants from the south.

A forthcoming study by researchers from Harvard University analyzed the DNA of nine late Stone Age individuals from Tunisia and Algeria (PRJEB83667).

Moreover, one sample from Djebba, Tunisia, revealed European hunter-gatherer ancestry dating back to around ~8,000 BP, likely due to human migrations across the Sicilian Straits.

These findings align with earlier genetic data from Taforalt and Ifri n'Amr Ou Moussa caves in Morocco.
