The brash antics of Republican U.S. presidential nominee Donald Trump have earned him a comparison to a male chimpanzee by renowned anthropologist Jane Goodall.
Known for her decades-long study of chimpanzee social and family life, Goodall made the comments in the October issue of The Atlantic for a story about the upcoming debates pitting Trump against his Democratic rival, Hillary Clinton.
"In many ways the performances of Donald Trump remind me of male chimpanzees and their dominance rituals," Goodall said in an interview shortly before Trump clinched the GOP nomination.
