Quote from Simões et al. 2023 preprint:
We also generated new genomic data from the Maghrebi Middle Neolithic and identified the introduction of new ancestry, from the Levant. This ancestry, which has not been observed on the European side of the Mediterranean, is identified in association with a new ceramic tradition in northern Morocco and a pastoralist lifestyle, as a consequence of the expansion of cattle pastoralism in the current Sahara territory [168]. Levantine gene flow has been previously identified in pastoralist Neolithic East African individuals living around 4,000 years ago [169].
