58: Expression Unleashed (with Thom Scott-Phillips and Joshua Blackburn)

Today, we communicate. But once, we didn't. What had to happen in our brains to make communication possible? And why don't other animals do it like we do? We talk to Dr Thom Scott-Phillips about his new work in the social and cognitive origins of communication. And game creator Joshua Blackburn is going to test Daniel's linguistic prowess with questions from the hottest game on Kickstarter, League of the Lexicon.
