The origins of modern man: Q and A with Stephen Oppenheimer

Where did the modern human race originate? And how did we disperse throughout the globe? These questions form the basis for the BBC series The Incredible Human Journey, which this weekend features genetics expert and Prospect contributor Stephen Oppenheimer. Indeed, much of the series draws upon Oppenheimer's 2003 work, Out of Eden: the peopling of the world, previously featured in Prospect.

To coincide with Sunday's programme, Oppenheimer has agreed to address a limited number of questions on the journey and the research upon which it was based (as he did previously for Prospect on his 2006 book The Origins of the British). So if you feel Sunday's show leaves any stones unturned, or if you have any burning questions about the birth of humanity, now is you chance to be heard--leave your questions below, and Oppenheimer will reveal all.
