Using palaeogenetics to unravel the impact of humans on animal populations in the past

Abstract : Palaeogenetics has the potential to reconstruct past genetic diversity of species and/or populations and to reveal evolutionary processes that would otherwise remain hidden when relying only on modern genetic data. After a general presentation of the limits and potentials of palaeogenetics, we summarize a series of studies from our lab that allow us to compare the evolution of genetic diversity of various animal species since the end of the Pleistocene, that have had different relationships with humans with respect to their domestication or avoidance therefrom. We show that, even though domestication initially involved only a subset of a larger wild population, regular gene flow from wild to domestic animals allowed the latter to retain a higher genetic diversity than related wild populations many of which experienced a severe, human-driven population reduction during the Holocene.
