Do cells have goals? | with Melanie Challenger, Nick Lane & Philip Ball

Is purpose something our brains invented, or is it built into life itself? Three thinkers take on one of science's oldest unresolved questions: what does it mean to be alive? Author Melanie Challenger is joined by biochemist Nick Lane and science writer Philip Ball for a live inquiry that begins with Richard Dawkins's claim that nature exists without purpose, and asks whether recent biology points somewhere different.
