(B) Main migration routes of B2y as inferred from phylogeographic data. (C) Network of B2y CR haplotypes obtained from population surveys (listed in Supplemental Table S2). (D) Interpolated frequencies of B2y mtDNAs in America. See the legend of Figure 1 for more details on the phylogenies of panels A and C.
