As these peoples migrated they replaced all other human populations with little or no interbreeding. The current best explanation for the beginning of modern humans is the Out of Africa Model that postulates a single, African origin for Homo sapiens.

Neanderthals and modern humans coexisted in some parts of the world for thousands of years. It was characterized by significant innovation: The Upper Paleolithic lifestyle, as it was called, was based essentially on hunting and gathering.
In assessing the degree of difference between DNA in Neanderthals and modern humans, the authors suggest that these two lineages have been separated for more thanyears.
Map of early diversification of modern humans according to mitochondrial population genetics see: This is a classic example of geographic isolation leading to a speciation event.
The fossil archaic humans that we find throughout the Old World belonged to these several species, but only one branch of this ancient family tree could give rise to today's humanity. Despite this, multiregionalism is still confused with polygenism, or Coon's model of racial origins, from which Wolpoff and his colleagues have distanced themselves.
Some scientists describe the current picture as a multiregional evolution scenario, others describe it as an out of Africa scenario, and still others describe it as a blend or middle ground between the two.
