Donald Trump's debates the way chimpanzees try to dominate rivals, according to remarks from the world's most famous expert on chimpanzees.
"In many ways the performances of Donald Trump remind me of male chimpanzees and their dominance rituals,"Jane Goodall, the world-famous primatologist and anthropologist, told the Atlantic's James Fallows for a piece posted Saturday.
Male chimpanzees try to impress rivals with aggressive behavior, Goodall said, such as stamping and throwing rocks. "The more vigorous and imaginative the display," the more likely it is that the chimp will rise atop the hierarchy and remain.
During his GOP primary debates, Trump reminded Goodall of a particular chimp named Mike, she said.
Trump's debate performances were marked by his penchant for applying belittling monikers to opponents and employing self-aggrandizing rhetoric.
He termed Florida senator Marco Rubio "Lil' Marco," and Texas senator Ted Cruz "Lyin' Ted," while repeatedly demeaning former Florida governor Jeb Bush as "low-energy."
He made frequent self-aggrandizing references to his wealth and success, and even boasted at one point that he was well-endowed in terms of his male anatomy.
Trump has indicated that he won't change his approach significantly to debate Hillary Clinton later this month. He has already engaged in behavior meant to throw off his opponent, raising doubts that Clinton is physically prepared to debate him.
