A mysterious group of apes found in the war-torn Democratic Republic of Congo in central Africa has scientists and conservationist scratching their heads. The apes nest on the ground like gorillas but have a diet and features characteristic of chimpanzees.
The apes are most likely a group of giant chimpanzees that display gorilla-like behavior. A far more remote possibility is that they represent a new subspecies of great ape. Researchers plan to return to the region later this month to collect more clues to help resolve the mystery.
Shelly Williams, an independent primate behavior specialist in Atlanta, Georgia, who has a doctorate in experimental psychology, spent two months in the northern Democratic Republic of Congo last year trying to determine the identity of these apes. She said "at the very least, we have either a new culture of chimps that are unusually large or hybrids with unusual behaviors."
Williams and Groves will meet Ammann in Kenya this month before traveling to the Congo to conduct further studies on the mysterious apes.
Ground Nesting Chimp?
Since Ammann launched his quest, he has led expeditions into the Bili forest in the northern Democratic Republic of Congo where the original skulls were recovered. On his first trip, Ammann recovered a skull which had a pronounced ridge on its forehead characteristic of gorilla. The rest of the measurements link the skull to that of a chimpanzee.
