What is Life?

Brian Cox and Robin Ince are joined by comedians Jo Brand and Ross Noble, alongside Nobel Prize winner Sir Paul Nurse and geneticist Prof Aoife McLysaght to ask the biggest question of all, what is life and how did it start? They look at the amazing feat of nature that has somehow created all of life from just four fundamental units of simple chemistry. From chickens to butterflies to yeast, we are all far more closely related then we think. But how did the spark of life occur and what has any of this got to do with Ewoks? Producer: Alexandra Feachem
