This group was eventually replaced and assimilated by the incoming Neolithic farmers. The western Atlantic fa\u00e7ade was home to some of the last Mesolithic sites of mainland Europe, represented by the iconic open-air sites at Hoedic and T\u00e9viec in southern Brittany, France. These sites are known for the unusually well-preserved and rich burials. Genomic studies of Mesolithic European hunter-gatherers have been limited to single or a few individuals per site and our understanding of the social dynamics of the last Mesolithic hunter-gatherers of Europe and their interactions with incoming farmers is limited. We sequenced and analyzed the complete genomes of 10 individuals from the Late Mesolithic sites of Hoedic, T\u00e9viec, and Champigny, in France, four of which sequenced to between 23- and 8-times genome coverage. The analysis of genomic, chronological and dietary data revealed that the Late Mesolithic populations in Brittany maintained distinct social units within a network of exchanging mates. This resulted in low intra-group biological relatedness that prevented consanguineous mating, despite the small population size of the Late Mesolithic groups. We found no genetic ancestry from Neolithic farmers in the analyzed hunter-gatherers, even though some of them may have coexisted with the first farming groups in neighboring regions. Hence, contrary to previous conclusions based on stable isotope data from the same sites, the Late Mesolithic forager community was limited in mate-exchange to neighboring hunter-gatherer groups, to the exclusion of Neolithic farmers.", "doi": "10.1073/pnas.2310545121", "pmid": "38408241", "labels": {"NGI Short read": "Service", "NGI Uppsala (SNP&SEQ Technology Platform)": "Service", "National Genomics Infrastructure": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC10927518"}], "notes": [], "created": "2024-02-27T13:17:58.460Z", "modified": "2024-11-25T10:22:31.622Z"}, {"entity": "publication", "iuid": "2aed043e07494edeb8d66c6047ca7cfd", "links": {"self": {"href": "https://publications.scilifelab.se/publication/2aed043e07494edeb8d66c6047ca7cfd.json"}, "display": {"href": "https://publications.scilifelab.se/publication/2aed043e07494edeb8d66c6047ca7cfd"}}, "title": "Northwest African Neolithic initiated by migrants from Iberia and Levant.", "authors": [{"family": "Sim\u00f5es", "given": "Luciana G", "initials": "LG", "orcid": "0000-0002-6119-9776", "researcher": {"href": "https://publications.scilifelab.se/researcher/eea5b7ccd8f84d44b2e0be03f5c4e762.json"}}, {"family": "G\u00fcnther", "given": "Torsten", "initials": "T", "orcid": "0000-0001-9460-390X", "researcher": {"href": "https://publications.scilifelab.se/researcher/84159bff82a64a938bcff107f550c901.json"}}, {"family": "Mart\u00ednez-S\u00e1nchez", "given": "Rafael M", "initials": "RM"}, {"family": "Vera-Rodr\u00edguez", "given": "Juan Carlos", "initials": "JC"}, {"family": "Iriarte", "given": "Eneko", "initials": "E", "orcid": "0000-0001-8365-5616", "researcher": {"href": "https://publications.scilifelab.se/researcher/112f0c5761e84deea89b2b7cb68521ce.json"}}, {"family": "Rodr\u00edguez-Varela", "given": "Ricardo", "initials": "R"}, {"family": "Bokbot", "given": "Youssef", "initials": "Y"}, {"family": "Valdiosera", "given": "Cristina", "initials": "C", "orcid": "0000-0003-4948-2226", "researcher": {"href": "https://publications.scilifelab.se/researcher/113ef0dde1dd48e388f75c43bd672005.json"}}, {"family": "Jakobsson", "given": "Mattias", "initials": "M", "orcid": "0000-0001-7840-7853", "researcher": {"href": "https://publications.scilifelab.se/researcher/8a4abe0fcb20492d9ec849c9fbf58a71.json"}}], "type": "comparative study", "published": "2023-06-00", "journal": {"title": "Nature", "issn": "1476-4687", "issn-l": "0028-0836", "volume": "618", "issue": "7965", "pages": "550-556"}, "abstract": "In northwestern Africa, lifestyle transitioned from foraging to food production around 7,400 years ago but what sparked that change remains unclear. Archaeological data support conflicting views: (1) that migrant European Neolithic farmers brought the new way of life to North Africa1-3 or (2) that local hunter-gatherers adopted technological innovations4,5. The latter view is also supported by archaeogenetic data6. Here we fill key chronological and archaeogenetic gaps for the Maghreb, from Epipalaeolithic to Middle Neolithic, by sequencing the genomes of nine individuals (to between 45.8- and 0.2-fold genome coverage). Notably, we trace 8,000 years of population continuity and isolation from the Upper Palaeolithic, via the Epipaleolithic, to some Maghrebi Neolithic farming groups. However, remains from the earliest Neolithic contexts showed mostly European Neolithic ancestry. We suggest that farming was introduced by European migrants and was then rapidly adopted by local groups. During the Middle Neolithic a new ancestry from the Levant appears in the Maghreb, coinciding with the arrival of pastoralism in the region, and all three ancestries blend together during the Late Neolithic. Our results show ancestry shifts in the Neolithization of northwestern Africa that probably mirrored a heterogeneous economic and cultural landscape, in a more multifaceted process than observed in other regions.", "doi": "10.1038/s41586-023-06166-6", "pmid": "37286608", "labels": {"NGI Short read": "Service", "NGI Uppsala (SNP&SEQ Technology Platform)": "Service", "National Genomics Infrastructure": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC10266975"}, {"db": "pii", "key": "10.1038/s41586-023-06166-6"}], "notes": [], "created": "2023-11-29T10:51:14.891Z", "modified": "2024-01-16T13:48:33.294Z"}]}
