Significant genetic differences found in three types of chimpanzee

The largest study to date of genetic variation among chimpanzees has found that the traditional, geography-based sorting of chimps into three populations,western, central and eastern, is underpinned by significant genetic differences, two to three times greater than the variation between the most different human populations.
