摘要
The lineage of Homo sapiens probably originated in Africa at least similar to 500kya. About 430kya, it split into three lineages of independently evolving human populations: Sapiens, Neanderthals and Denisovans. After several hundred thousands years, they met several times and interbred with low frequency. Evidence of coupling between them is found in fossil records of Neanderthal - Sapiens offspring (Oase 1) and Neanderthal - Denisovans (Denisova 11) offspring. Moreover, the analysis of ancient and present-day population DNA shows that there were several significant gene flows between populations. Many introgressed sequences from Denisovans and Neanderthals were identified in genomes of currently living populations. All these data, according to biological species definition, may indicate that populations of H. sapiens sapiens and two extinct populations H. sapiens neanderthalensis and H. sapiens denisovensis are one species. Ontological transitions from pre-human beings to humans might have happened before the initial splitting of the Homo sapiens population similar to 430kya or after the splitting during evolution of H. sapiens sapiens lineage in Africa. If the ensoulment of the first homo occurred in the evolving populations of H. sapiens sapiens, then occasionally mixed couples (Neanderthals - Sapiens or Denisovans - Sapiens) created relations that functioned as a family, in which children could have matured.
