Brian Cox and Robin Ince are joined on stage by comedian Shappi Khorsandi, science broadcaster Adam Rutherford and evolutionary geneticist Mark Thomas. They look at the thorny issue of race, and whether there is a scientific definition for the concept of race. Do our genes reveal racial differences, and if so do they tell us anything about our evolutionary history? They also look at the results of their own personal DNA tests...so which panellist is a little bit neanderthal and which one has a genetic history firmly rooted in the North! Producer: Alexandra Feachem.
