Genome-wide evidence of Austronesian-Bantu admixture and cultural reversion in a hunter-gatherer group of Madagascar
The Mikea are the last known Malagasy population reported to be still practicing a hunter-gatherer lifestyle. Earlier writers thought the Mikea were descended from ancient forager groups who have maintained their way of life up to the present. However, our analyses show that the Mikea are not a remnant population and, to the contrary, derived from a recent admixture of two agriculturalist populations: the Bantu (from Africa) and the Austronesian (from east-Asia). Thus, it is probable that the Mikea have adopted their hunter-gatherer way of life through a recent cultural reversion.
