Master Minds

S1, E3: There's one thing that sets us primates apart from most other families on the planet, and that's a flexible mind. Our primate cousins are much smarter than you might imagine. Just like us they use tools, solve problems, and even have emotions. We discover how these animals are individuals with a sense of self and why brainpower is essential to primate survival. In Thailand, long-tailed macaques floss their teeth with human hair and use tools to open oysters on the beach. In Uganda, chimps pass on cultures and customs through generations. We meet Dora at orangutan school in Sumatra and a bonobo in the US who can have conversations with humans and toast marshmallows in a fire he makes himself.
