Primatologist Jane Goodall analyzes Trump's behavior - as a primate [View all]
From the Independent.co: Donald Trump: World-renowned primatologist Jane Goodall likens US President to a chimpanzee:
In many ways the performances of Donald Trump remind me of male chimpanzees and their dominance rituals, she told The Atlantic during the 2016 presidential election.
In order to impress rivals, males seeking to rise in the dominance hierarchy perform spectacular displays: Stamping, slapping the ground, dragging branches, throwing rocks."
A more aggressive display was likely to lead the male to higher positions in the hierarchy and allow it to maintain its status for longer, she said.

Dame Jane's analysis of Mr Trump's behaviour has since been echoed by prominent psychologist Professor Dan P McAdams.
Describing what he called a male chimpanzee's "charging display" in an article in The Guardian, Professor Adams, of Northwestern University, said: "The top male essentially goes berserk and starts screaming, hooting, and gesticulating wildly as he charges toward other males nearby."
Dame Jane also had some harsh words for Trump taking the US out of the Paris Climate Accords.
