There are currently more than eight billion human beings living on Earth, occupying nearly every corner of the planet. It’s a remarkable situation to find ourselves in, and there can be little doubt that the story of human progress has, by and large, been a successful one. But how did we reach this point? What sets us apart from other animals? And what is it about our biology that has allowed us to achieve this incredible feat?

In this episode, we catch up with astrobiologist and author Prof Lewis Dartnell to talk about his latest book Being Human: How Biology Shaped World History.

He takes us on a trip through the evolution of the human race. We talk about how human beings’ ability to form harmonious societies has helped us prosper, why we’re so prone to making errors in judgment despite our great success as a species and how the world we’ve built has ended up influencing our biology back in return.
