In evolutionary biology, gene flow describes the exchange of genetic material between two populations of a species or within a population. In anatomically modern humans ( Homo sapiens ), gene flow from archaic humans to Homo sapiens has also been proven, u. a. between Neanderthals and Homo sapiens and between Denisovans and Homo sapiens , since these species had not yet moved too far genetically.
