    Ancient West African Foragers in the Context of African Population History
    (Springer Science and Business Media LLC, 2020-01) Lipson, Mark; Rohland-Pinello, Nadin; Lawson, Ann; Lavachery, Philippe; Mindzie, Christophe Mbida; Orban, Rosine; Semal, Patrick; Van Neer, Wim; Veeramah, Krishna R.; Kennett, Douglas J.; Patterson, Nick; Hellenthal, Garrett; Lalueza-Fox, Carles; MacEachern, Scott; Prendergast, Mary E.; Reich, David; Ribot, Isabelle; Mallick, Swapan; Olalde, Inigo; Adamski, Nicole; Broomandkhoshbacht, Nadin; López, Saloa; Oppenheimer, Jonas; Stewardson, Kristin; Asombang, Raymond; Bocherens, Herve; Bradman, Neil; Culleton, Brendan; Cornelissen, Els; Crevecoeur, Isabelle; de Maret, Pierre; Fomine, Forka Leypey Mathew; Sawchuk, Elizabeth; Thomas, Mark
    We generated genome-wide DNA data from four children buried roughly 8000 and 3000 years ago at Shum Laka (Cameroon), one of the earliest archaeological sites within the probable homeland of Bantu languages. One individual carried the deeply divergent Y chromosome haplogroup A00, which is found today almost exclusively in the same region. However, all four individuals’ genome-wide ancestry profiles are most similar to West-Central African hunter-gatherers, implying that present-day populations in western Cameroon, as well as Bantu speakers across the continent, are not descended substantially from the population represented by these four people. We infer an Africa-wide phylogeny that features widespread admixture and three prominent radiations, including one giving rise to at least four major lineages deep in the history of modern humans.

    Entwined African and Asian Genetic Roots of Medieval Peoples of the Swahili Coast

    The urban peoples of the Swahili coast traded across eastern Africa and the Indian Ocean and were among the first sub-Saharan practitioners of Islam [1, 2]. The extent to which these early interactions between Africans and non-Africans were accompanied by genetic exchange remains unknown. We report ancient DNA data for 80 individuals from six medieval and early modern (1250-1800 CE) coastal towns and an inland town postdating 1650 CE. Many coastal individuals had over half their DNA from primarily female African ancestors, with large proportions and occasionally more than half from Asian ancestors. The Asian ancestry included both Persian and Indian-associated components, with eighty to ninety percent from Persian males. Peoples of African and Asian origins began to mix by about 1000 CE, coinciding with large-scale adoption of Islam. Before about 1500 CE, the Southwest Asian ancestry was mainly Persian-related, consistent with the narrative of the Kilwa Chronicle, the oldest history told by people of the Swahili coast [3]. After this time, the sources became increasingly Arabian, consistent with evidence of growing interactions with southern Arabia [4]. Subsequent interactions with Asians and Africans further changed the ancestry of Swahili coast people relative to the medieval individuals whose DNA we sequenced.

    Ethics of DNA Research on Human Remains: Five Globally Applicable Guidelines

    We are a group of archaeologists, anthropologists, curators, and geneticists representing 24 countries and diverse global communities, most of whom met in November 2020 in a virtual workshop dedicated to ethics in ancient DNA research. There was widespread agreement that globally applicable ethical guidelines are needed, but that recent recommendations grounded in discussion about research on human remains from North America are not always generalizable worldwide. After considering diverse contexts, we developed a set of globally applicable guidelines. These hold that: 1) researchers must ensure that all regulations were followed in the places where they work and from which the human remains derived; 2) researchers must prepare a detailed plan prior to beginning any study; 3) researchers must minimize damage to human remains; 4) researchers must ensure that data are made available following publication to allow critical reexamination of scientific findings; and 5) researchers must engage with other stakeholders from the beginning of a study and ensure respect and sensitivity to stakeholder perspectives. We commit to adhering to these guidelines and expect they will promote a high ethical standard going forward.
