Comparing models on the genealogical relationships among Neandertal, Cro-Magnoid and modern Europeans by serial coalescent simulations

摘要: Populations of anatomically archaic (Neandertal) and early modern (Cro-Magnoid) humans are jointly documented in the European fossil record, period between 40 000 25 years BP, but large differences their cultures, morphologies DNAs suggest that two groups were not close relatives. However, it is still unclear whether any genealogical continuity them can be ruled out. Here, we simulated a broad range demographic scenarios by means serial coalescence algorithm which Neandertals, Cro-Magnoids Europeans either part same mitochondrial genealogy or separate genealogies. Mutation rates, population sizes, structure growth rates varied across simulations. All models (that is, Cro-Magnoid current) belong to distinct performed better than model three assigned genealogy. The maximum admissible level gene flow Neandertals ancestors current 0.001% per generation, one order magnitude lower estimated previous studies considering genetic data on people.
