This year's Reith lecturer is the Professor of Zoology and Comparative Anatomy at University College London, Peter Brian Medawar. His work on graft rejection and the discovery of acquired immune tolerance has been fundamental to the practice of tissue and organ transplants. In his Reith lecture series entitled 'The Future of Man', Professor PM Medawar considers how humans will continue to evolve in the future.

In his fourth lecture entitled 'The Genetic System of Man', Professor PM Medawar explores the eugenics of human beings, and questions the effect our natural habitat has on our genes. He explores how our genetic inheritance and fertility respond to our surrounding environment. Show less
