(A) Location of KS and LM and areas from which desert (D) and riverine (R) populations were sampled (41). (B) Phylogenetic tree of mtDNA sequences, with their ages, from ancient (blue, robust; green, gracile) and living Aboriginal Australians (black), the Feldhofer Neandertal, the mitochondrial genome-derived nuclear insert (Insert), and the Cambridge Reference Sequence, with chimpanzee and bonobo sequences used as outgroups. Relative likelihood support (47) is shown for branches A, B, and C.
