Ethiopian mtDNA shows 50-50 admixture. Semitic-speaking Ethiopians have far higher Y-DNA admixture than Cushitic speakers. Semitic Ethiopians thus expected to carry more Neanderthal DNA. Non-African mtDNA/Y-DNA alleles differ strictly from African ones yet not labeled Neanderthal. African alleles identical to chimp sequences are likely homoplastic and derived. True root is chimp T > Neanderthal/non-African C > African T. Africa holds oldest lineages that are most derived and distant from homeland. Rosenberg 2002 shows K-cluster split with least derived Amerindians versus most derived Africans. No admixture proof beats genetic drift rival. Europeans and Asians share Neanderthal-like traits from cold adaptation drift, not Neanderthal contact. Asians adapted like Neanderthals from erectus via drift. Occam's razor crushes admixture hypothesis.
