 Human/chimpanzee divergence
There is little or no disagreement that the common ancestor of humans and chimpanzees lived in Africa and that the original divergence of the two lineages took place in that continent.
One hypothesis for this mechanism is that part of the population of the common ancestor became geographically isolated from the rest of the population over a long period of time, perhaps owing to a barrier such as the Rift Valley, or mountains or rivers.
In the case of human and chimpanzee, the divergence occurred sufficiently long ago that there are significant numbers of rearrangements in the chromosomes but not so long that all chromosomes have rearrangements.
