DNA of mystery apes studied by scientists

Scientists in the United States hope DNA tests will reveal the origins of large, mysterious apes discovered in the heart of Africa.

Genetics research at Omaha's Henry Doorly Zoo on faecal samples collected from the rare apes should determine if they are a new species, a new subspecies or a form of hybrid possibly a mix between a chimpanzee and a gorilla. "It is a new, mystery ape and we are doing the DNA fingerprinting to find out more," said zoo director Dr Lee Simmons.

The apes, which stand five to six feet tall and have feet nearly 14 inches long, were first documented by primatologist Shelly Williams of Atlanta in a forest in the northern Democratic Republic of Congo.

They have bodies similar to those of gorillas, but generally the facial characteristics of a chimpanzee.

"I can't speculate yet as to what they are. Their behaviour is so unusual. It is a puzzle. I feel like Dr Doolittle in the land of Oz," said Williams, who has captured some video of the animals but no photographs.

Because of their size and elusiveness, the apes have no predators not even poachers hunt them, Williams said. With no fear of lions, leopards or hyenas, the large animals hoot at the moon as it rises and sets, which is extremely unusual for apes, she said.
