Cognitive Revolution (Sapiens): How Gossip Changed Our Brains

What was the Cognitive Revolution in Sapiens? How did it allow our species to survive, while other human species, such as Neanderthals, disappeared? The Cognitive Revolution was the moment in human history when our ancestors developed three new abilities: flexible language, communication about 3rd parties, and collective fictions.

This evolution gave humans a leg-up in the animal world. We’ll cover the characteristics of the evolution of human intelligence and how that evolution shaped the modern world.
