PROGRAM DESCRIPTION: Humans work together on enormous scales to build complex tools as large as cities and create social networks that span the globe. What is the key to our success? This program examines the development of the human brain — and the brains of other animals — asking how neurons orchestrate communal behavior and guide group interactions, demonstrating how our social nature is key to our humanity. PARTICIPANTS: Louise Barrett, Agustín Fuentes, Kevin Laland, Kevin Ochsner, Dietrich Stout MODERATOR: John Donvan Original program date: JUNE 2, 2017 WATCH THE LIVE Q&A WITH LOUSIE BARRETT: as part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
