<P> Alleles occur at different frequencies in different human populations , with populations that are more geographically and ancestrally remote tending to differ more , a phenomenon known as isolation - by - distance . The differences between different populations represent a small proportion of overall human genetic variation . Populations also differ in the quantity of variation among their members , with greatest diversity among African populations . This is consistent with the theory that humans recently migrated out of Africa . Populations also vary in the ( always small ) proportion of DNA they received from archaic hominid populations , such as Neanderthals and Denisovans . </P>
