Professor Chris Stringer has worked at The Natural History Museum London since 1973. He is now Research Leader in Human Origins and a Fellow of the Royal Society, and is also a Visiting Professor at Royal Holloway and UCL. His early research was on the relationship of Neanderthals and early modern humans in Europe, but through his work on the 'Recent African Origin' theory of modern human origins, he now collaborates with archaeologists and geneticists in attempting to reconstruct the evolution of modern humans globally. His recent books include The Complete World of Human Evolution, The Origin of Our Species and Britain: One Million Years of the Human Story. We talk about Human Evolution, the prehistoric world we shared with other Hominins, the demise of the Neanderthals, my big nose and Ozzy Osbourne's DNA.
