Adcock et al. recovered no authentic ancient Aboriginal mtDNA from Willandra Lakes remains. Mungo Man (WLH3) contained five European mtDNA haplogroups including H1, H3, H15a1, U5a, H40b. WLH15 and WLH55 had no identifiable human DNA. WLH4 yielded 1.4% human DNA including authentic Aboriginal S2 haplogroup mtDNA and European V3c contaminant. S2 haplogroup from WLH4 matches modern Aboriginal Australians and dates MRCA to 28,500-35,500 years. KS8 original extracts showed European haplogroup K contamination matching researcher Adcock. Adcock's unique WLH3 and KS8 sequences fell outside modern variation due to PCR artifacts and long-branch attraction. No evidence for mitochondrial lineages predating modern humans in ancient Australians. Robust and gracile morphologies not explained by population replacement or selective sweeps. Contemporary Aboriginal mtDNA consistent with single migration and Out-of-Africa model. Short HVR1 locus unreliable for human phylogeny due to mutational saturation. Aboriginal Australians show small Denisovan and Neanderthal admixture per genomic studies. First complete ancient Aboriginal mtDNA genome (S2) recovered from Holocene WLH4. Contamination from handling unavoidable without ancient DNA labs. Future nuclear genomes possible from Australian remains.
