TL;DR: Genomic data from seven 15,000-year-old modern humans attributed to the Iberomaurusian culture from Morocco are presented, finding a genetic affinity with early Holocene Near Easterners, best represented by Levantine Natufians, suggesting a pre-agricultural connection between Africa and the Near East.
Abstract: North Africa is a key region for understanding human history, but the genetic history of its people is largely unknown. We present genomic data from seven 15,000-year-old modern humans, attributed to the Iberomaurusian culture, from Morocco. We find a genetic affinity with early Holocene Near Easterners, best represented by Levantine Natufians, suggesting a pre-agricultural connection between Africa and the Near East. We do not find evidence for gene flow from Paleolithic Europeans to Late Pleistocene North Africans. The Taforalt individuals derive one-third of their ancestry from sub-Saharan Africans, best approximated by a mixture of genetic components preserved in present-day West and East Africans. Thus, we provide direct evidence for genetic interactions between modern humans across Africa and Eurasia in the Pleistocene.
TL;DR: Some measure of long-term population continuity in the Maghreb and surrounding region is supported, whereas greater North African population heterogenity during the Late Pleistocene is implied.
TL;DR: In this paper, the authors present new AMS dating results from well-stratified cave sequences at Ghar Cahal, Kehf el Hammar and Taforalt in northern and eastern Morocco.
Abstract: Chronological evidence for the Iberomaurusian is currently very limited and there are problems with some of the published radiocarbon dates. In this paper we present new AMS dating results from well-stratified cave sequences at Ghar Cahal, Kehf el Hammar and Taforalt in northern and eastern Morocco. The longest of these sequences, from Taforalt, shows an intermittent occupation history spanning the period ca. 18,000–11,000 bp (radiocarbon determinations presented in this paper are expressed as ka bp or bp, whilst approximate calendar ages are expressed as Cal bp) with a marked intensification of cave use soon after ca. 13,000 bp. Using calibrated AMS ages in comparison to sea surface temperature evidence from the Alboran Sea core MD95-2043 and more generally to Greenland ice δ18O core records, we suggest that there may have been a relationship, albeit a complex one, between climatic events and cave activity on the part of Iberomaurusian populations.
TL;DR: New work on the Middle (MSA) and Later Stone (LSA) Age deposits at Taforalt Cave in Morocco offers fresh light on theories of continuity versus replacement of populations as presented by the genetic evidence, and examines the implications for interpreting the first appearance of the LSA in the Maghreb.
TL;DR: The Southern Mediterranean Neolithic as mentioned in this paper follows the Aterian and precedes both the Neolithic of Capsian tradition and preceded both the Southern Mediterranean and the Southern American Neolithic.
Abstract: RELATIVE TIME PERIOD: Follows the Aterian and precedes both the Neolithic of Capsian tradition and the Southern Mediterranean Neolithic.
