Bacho Kiro Cave in Bulgaria holds Europe's oldest Homo sapiens ornaments over 43,000 years old. Remains dated 46,000 years include Homo sapiens mandibles confirmed by DNA and morphology. Three Initial Upper Paleolithic individuals from 44,000-40,000 years ago had high Neanderthal ancestry from ancestors six or seven generations back. These individuals share more alleles with East Asians, Central Asians, and Native Americans than West Eurasians. Bacho Kiro population belonged to Ancient East Eurasian wave linked to Ust'-Ishim, Tianyuan, and Papuan ancestors. They relate closely to Oase specimens and contributed to Aurignacian and Gravettian Europeans. GoyetQ116-1 derives 19% ancestry from Bacho Kiro-like source. Tianyuan man derives up to 39% from IUP source related to Bacho Kiro. IUP remains pre-date East Asian-European split or represent earliest East Eurasian expansion with archaic admixture. Multiple Out of Africa dispersals explain East Asians' deeper split from Africans than Europeans. Bacho Kiro could stem from Asian migration of modern humans. Later 35,000-year-old BK1653 individual relates more to modern Europeans than East Asians. Mitochondrial haplogroups include M, N, R, and U8. Bacho Kiro IUP got absorbed by later West Eurasian Upper Paleolithic wave.
