Gene flow: multi regional idea: gene flow maintained a single species which is why we are able to be h. sapiens, ooa says there was no gene flow. They just left africa and replaced all other species. Genetic studies: more genetic diversity in africa than anywhere else in the world they"re been adapting longer than any other place, supports ooa 2. Krings et al 1999: supports ooa 2, we haven"t changed since, no gene flow, last contact was with neandertals.
