Primate expert Dr Jessica Mayhew told Newsweek that while this isn't the first time such an incident has been reported, this behavior is "uncommon."

"The discovery of a new bone in a new species is a rare event, especially in chimps which have such similar anatomy to people," researcher Catrin Rutland said.

Back in 1979, I was looking for gibbons in Khao Yai National Park in Thailand. There in front of us, about 30 feet away, was a large tiger lying in the middle of the trail.

"It is like finding a new fossil of a long-lost ancestor," researcher Chris Petkov said.

It is thought about 25 percent of respiratory diseases are transferred through face-touching.

Scientists also observed the chimps sharing the tortoise meat between individuals.

Using tools to dig for food underground was once thought to be a behavior unique to humans.

Scientists were surprised to find the genitalia of female dolphins are packed full of nerves.

The research could have implications for identifying early signs of developmental disorders in children.
