Pygmy Chimpanzee Systematics
The biological understanding of any group of organisms is greatly facilitated by having its phylogeny available. That phylogeny, in both its cladistic and temporal aspects, is most readily derived, at least for living and recently extinct forms, from comparative studies of proteins and nucleic acids. The pygmy chimpanzee (Pan paniscus) provides a particularly intriguing test case for these claims, there having been a great deal of difficulty in understanding the species in its own right, as well as in developing an appreciation of what, if anything, it has to tell us about our own evolution.
