Your own citation states that morphologically Capsians were of proto-Mediterranean type.Are you confused? The quote deals with Aterian culture, the earliest settlements of NW Africa and their indigenous origins. Here's wiki on the Capsian culture which actually shows ties to Berber culture, unlike groups of 30ka..
-- The Capsian culture (named after the town of Gafsa in Tunisia) was a Mesolithic culture of the Maghreb, which lasted from about 10,000 to 6,000 BCE. It was concentrated mainly in modern Tunisia, and Algeria, with some sites attested in southern Spain to Sicily. It is traditionally divided into two horizons, the Capsien typique (Typical Capsian) and the Capsien supérieur (Upper Capsian) which are sometimes found in chronostratigraphic sequence. They represent variants of one tradition, the differences between them being both typological and technological.
During this period, the environment of the Maghreb was open savanna, much like modern East Africa, with Mediterranean forests at higher altitudes. 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. During the succeeding Neolithic of Capsian Tradition, there is evidence from one site, for domesticated, probably imported, ovicaprids.
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, whereas others argue for population continuity based on physical skeletal characteristics and other criteria,
Given its widespread occurrence in the Sahara, the Capsian culture is identified by some historical linguists as a possible ancestor of the speakers of modern Afroasiatic languages of North Africa which includes the Berber languages in North Africa.
Nothing is known about Capsian religion, but their burial methods suggest a belief in an afterlife. Decorative art is widely found at their sites, including figurative and abstract rock art, and ochre is found coloring both tools and corpses. Ostrich eggshells were used to make beads and containers; seashells were used for necklaces. The Ibero-Maurusian practice of extracting the central incisors continued sporadically, but became rarer.
The Eburran industry which dates between 13,000 and 9,000 BCE in East Africa, was formerly known as the "Kenya Capsian" due to similarities in the stone blade shapes.--
Again, there is no hard evidence suggesting Eurasian origin to Iberomaurusian/Capsian culture while Mechta-Afalou definitely aren't Eurasian or Cro-Magnon. Eurasian dna is old in NW Africa, but oldest/predominate?... Without considering ydna or origin of the material culture?
Show us a genetic study of ANY Maghreb site which does not have Eurasians present. I know that usually a site is entirely Eurasian; some are predominantly Eurasian.
Influences of African provenance are not surprising after 20k bp, when we know from the genetic and morphological evidence that there was an influx of Africans into the Maghreb.
The fact remains that the Maghreb for 30k years has been predominantly Eurasian.
It is likely that Afroasiatic languages originated in the Mideast and were brought into Africa by multiple migrations.
