Structures sociales et structures génétiques dans les populations humaines

Abstract : n this note, we summarize the talk given at the SAP conference 2019 regarding the field of ethnogenetics, that studies the influence of kinship systems on the genetic diversity of human populations.We will present some of the main results of an ethnogenetic study led in twelve Southeast Asian populations exhibiting various kinship systems, with matrilineal, patrilineal and cognatic descent. This study contributes to highlight that processes of residence, descent and alliance shape the genetic diversity of human populations. This opens new perspectives, notably understanding better the present dynamics of kinship systems thanks to genetic data, and tracing back their evolution through time thanks to archeogenetic data. However, this work also shows that the signatures left by a given type of social organization are variable depending on the extent to which the rule is observed, inviting to be careful when inferring past social systems from archeogenetic data. The genetic impact of the « matrilineal puzzle » is also discussed.
