Who are we? Why are we here? Are we alone in the universe? How did we become the creatures that we are? How might we further evolve? These are some of the big questions that Brian Cox and Alice Roberts tackled when they came to the Intelligence Squared stage in December. Brian Cox is the rockstar who became a scientist, and is now a rockstar scientist. He is known to millions as the presenter of the BBC Wonders series in which he unravels the complexities of the universe with calm clarity and an infectious sense of wonder. Alice Roberts is a no less talented science story-teller. A doctor, anatomist, osteoarchaeologist and writer, she has enthralled television audiences with BBC series such as The Incredible Human Journey. In this wide-ranging conversation Cox and Roberts discussed the origins of the universe, life and humanity – and you. You’re the product of what seems to be an extremely unlikely chain of events. Our universe was born with just the right laws for galaxies to form, with at least one planet capable of producing and sustaining life. The origin of muliticellular life on this planet was essentially an accident; the mammals were lucky to outlive the dinosaurs; a handful of two-legged apes survived, against the odds, on the plains of Africa… and then there’s the unlikeliness of your mother meeting your father and that particular sperm fusing with that particular egg. The chance of you being here at all is tiny. How can physics and biology help us to make sense of all that unlikeliness? How did chance and accident combine to create us?
