Modelling the Pathan, Vaish, Meghawal and Bhil as mixtures of ANI and ASI, and relating them to non-Indians by the phylogenetic tree (YRI,((CEU,ANI),(ASI, Onge))), provides an excellent fit to the data. Although the model is precise about tree topology and ordering of splits, it provides no information about population size changes or the timings of events. We estimate genetic drift on each lineage in the sense of variance in allele frequencies, which we rescale to be comparable to FST (standard errors are typically plusminus0.001 but are not shown).
