Joseph Henrich — Humans defeated smarter species with cultural evolution

Video Description

Humans have *not* succeeded because of our raw intelligence. Marooned European explorers regularly starved to death in areas where foragers thrived for 1000s of years. I’ve always found this cultural evolution deeply mysterious. How do you discover the 10 steps for processing cassava so it won’t give you cyanide poisoning simply by trial and error? Has the human brain declined in size over the last 10,000 years because we outsourced cultural evolution to a larger collective brain? The most interesting part of the podcast is Henrich’s explanation of how the Catholic Church unintentionally instigated the Industrial Revolution through the dismantling of intensive kinship systems in medieval Europe.
