The Role of Hormones in Reactive Aggression

What would a Neanderthal think about our species? What about a chimpanzee? When compared to our cousins, how friendly or violent are we?

Richard Wrangham is a chimpanzee expert and professor of human biology at Harvard. He is one of the most important evolutionary anthropologists alive and truly one of the dream guests for this podcast. It was a great honour to have him on the show. We discuss topics such as:

1. What makes studying chimpanzees interesting
2. Why you could not put 100 chimps on a plane (and not see a fight)
3. What about bonobos?
4. The goodness paradox: or why Wrangham thinks that humans are both a remarkably friendly and a relatively violent ape.
5. Are humans a child-like ape?
6. Why human skulls resemble dogs, not wolves
7. What five decades of research have taught Wrangham about humans

A suggestive timeline of human evolution (estimated years ago) 

• c. 6 million years ago: Last common ancestor of humans, chimpanzees and bonobos 
• 4 — 3 million years ago: Australopithecines
• 2.5 — 1.5 million years ago: Homo habilis (arguably the first human)
• 2 million — 100 thousand years ago: Homo erectus (first “proper” human according to Wrangham)
• 600 thousand — 300 thousand: Homo heidelbergensis (evolving to Neanderthals and us)
• 300 thousand — today : Homo sapiens
