Melvyn Bragg examines the future of gene therapy and advances in evolutionary biology. Are we continuing to evolve? If so, what are the signs and if not, why not? And those apes, so very very near us in genetic kinship, why are they so far away in so much else, and will they ever evolve? And is evolution necessarily progression? If so, does our apparent lack of evolution mean lack of progress? Also on the evolutionary front, could electronic devices discover the means of self-replication, and what will that mean for us? The march of the life sciences after the discovery of DNA accelerates by the year but what are the implications?With Professor John Maynard Smith evolutionary biological theorist and Emeritus Professor of Biology at the University of Sussex; Colin Tudge, writer, journalist and Research Fellow at the Centre for Philosophy.
