The Zlatý kůň woman is either associated with non-Mousterian and non-Initial Upper Paleolithic cultures or with early IUP-like cultures, one of the earliest cultures of modern humans in Europe, which expanded into Eurasia more than 45,000 years ago, following their dispersal out of Africa.[1][2][3] On the basis of genetic dating, the Zlatý kůň individual is believed to be the oldest anatomically modern human ever to be genetically sequenced. Her genome represents a deeply splitting lineage basal to the subsequent split between East Eurasians and West Eurasians.[4]
These early Eurasian populations probably mated with Neanderthals in the period between 50,000 and 60,000 years ago, probably during the initial phase of their expansion in the Middle East, and they carried ~2–9% Neanderthal ancestry in their genomes.[5] It is also considered that the early modern humans coexisted with Neanderthals in Europe for a period of about 3,000–5,000 years.[1] The Zlatý kůň woman had a small amount of Neanderthal admixture, going back 70 or 80 generations.[5]
These people do not appear to have been the ancestors of later Europeans, as the very few ancient DNA samples recovered from this period are not related to later samples.[6] The Zlatý kůň woman also has contributed genetically neither to later Europeans nor to Asians.[1]

A similarly recent hybridization event (six or seven generations earlier) has been inferred from aDNA of early modern humans at Bacho Kiro, Bulgaria, around 45.9–42.6 Ka [39], while a somewhat more distant event (70–80 generations earlier) has been recognized in the genome of a >45 Ka-old cranium from Zlatý kůň in Czechia

A complete genome has been produced from the ~45,000-year-old remains of Ust'-Ishim, a Siberian individual who showed no genetic continuity to later Eurasians. This contrasts with the ~40,000-year-old East Asian individual from Tianyuan, whose genome is more closely related to many present-day Asians and Native Americans than to Europeans. From Europe, only the partial genome of an individual called Oase 1 and dated to ~40 ka has been recovered, and this showed no evidence of shared ancestry with later Europeans
