Jag är ingen kreationist heller, så jag är öppen för förslag.
Vi kan väl konstatera att det måste ha skett innan vi förökade oss med neandertalare, och det var ju rätt länge sedan.
In May 2010, a first draft of a Neandertal nuclear genome was published for the first time (Green et al. 2010). About 4 billion base pairs, or roughly 2/3rds of of the entire genome, was sequenced from three individuals. Even more interestingly, analysis of the genome seems to show that Neandertals interbred with humans, and that all non-African modern humans contain between 1% and 4% of Neandertal genes. (A later paper, Reich et al. 2010, has narrowed that range to between 1.9% and 3.1% of Neandertal genes.) Because Asians as well as Europeans have these Neanderthal genes, the researchers believe the most likely explanation is that the interbreeding occurred in the Middle East when modern humans first left Africa between 60,000 and 80,000 years ago, and before they expanded into the rest of the world.
