'Denis Alexander has a rare skill. A first-rate scientist, working on fascinating problems of both intellectual and moral importance, he is able to speak to the general public in ways that are clear, without the slightest hint of condescension. At the cutting-edge of the science of genetics, Alexander takes us through the implications for nearly everything, from putting on weight to church attendance!  Read and learn from his book. Wonder at this incredible world in which we live and which we are now starting to understand.' Prof. Michael Ruse, Lucyle T. Werkmeister Professor of Philosophy, Florida State University
