Washington D.C. - A new study suggests that chimpanzee subspecies may be more genetically variable than humans and also more closely related to each other--two findings that conflict with some earlier research on chimpanzee genetic diversity. The study's results, reported by a group of German researchers in the 5 November issue of Science, impact on a number of hot topics in evolutionary anthropology, from the origin of modern humans to great ape conservation. The findings also support the idea that cultural differences between chimpanzee populations are probably not the result of genetic variation between these groups.
