Maximum likelihood tree for all publicly available (near) complete Aboriginal Australian mitochondrial genomes and that of WLH4. Major Australian haplogroups are marked as follows: S (red), O (magenta), P (turquoise), and M (green). The sequence from WLH4 clusters with haplogroup S and in particular, haplogroup S2. Previously published sequences are marked with numbers (SI Appendix, Table S6 has more details), and haplogroups are shown in parentheses.
