Testing for Ancient Admixture between Closely Related Populations
Testing for Ancient Admixture between Closely Related Populations
One enduring question in evolutionary biology is the extent of archaic admixture in the genomes of present-day populations. In this paper, we present a test for ancient admixture that exploits the asymmetry in the frequencies of the two nonconcordant gene trees in a three-population tree. This test was first applied …
