Page values for "Why chimpanzees throw feces"

The study aimed to investigate if there was a correlation between chimpanzees' ability to throw feces and their communication skills. This research drew from the hypothesis that the development of throwing skills in early hominins might have influenced the evolution of language and speech, particularly focusing on the left hemisphere specialization

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.
