Figure 2.

Maximum likelihood phylogeny of Clade I haplotypes. Ancient American dog haplotypes are on red branches. Clade Ia is highlighted with a label and the dashed rectangle highlights the only extant haplotype inferred to be derived from an ancient dog sequence. Tip labels correspond to non-redundant haplotypes from Table S1 or [1,3-5,7].
