Monkey Business - Robin Dunbar, Dave Gorman and Jo Setchell

In perhaps the monkiest Infinite Monkey Cage episode there’s ever been, Brian Cox and Robin Ince attempt to uncover the secrets of love, lust and friendship in primates. Swinging by to offer a hand (or tail) are evolutionary psychologist Robin Dunbar, anthropologist Jo Setchell, and comedian Dave Gorman. Together the panel explores Dunbar’s number in monkeys – the idea that the number of friendships an individual can maintain correlates with brain size – with the very creator of the theory!
