The study concluded that chimpanzees who are better at throwing objects, including feces, have more developed brains, particularly in areas associated with communication. Specifically, these chimpanzees showed more white matter in the homologue of Broca's area, which is linked to speech in humans.

It was conducted by William Hopkins at Emory University's Yerkes Primate Center.
