Not a new "species" of Great Ape after all

A few years ago there were reports of a new great ape in the Congo, perhaps a chimp-gorilla hybrid. As the story unfolded it seemed more and more plausible that this was a local morph of the common chimpanzee, and genetic tests have confirmed that hunch. It is a subspecies of common chimpanzee, though with unusual morphological features. The latter is important, we see a wide range of phenotypes among humans across small distances, so it should not surprise if chimpanzees also exhibit variation.
