#2: The biology of the right-left divide pt. 2: Raven politics
Updated: Dec 19, 2020
(05/12/2020) Having described the idiosyncratic constellation of traits that correlate with political outlook in the last episode, this time we'll examine the biology of aggression in other species, and how it is correlated with a very similar set of traits. We'll talk about a utopian experiment undertaken among baboons, a revolt against male aggression by female bonobos, foxes that act like dogs, the sex lives of domestic animals, and how young ravens are leftists and old ravens are rightists.
