"Essentially, what the thesis of the book is that science is really about finding simple solutions. And I guess one of the other themes of the book is that life appears like a scientist. It finds the simplest solutions to problems, and that's because there's a mechanism in natural selection, whereby stuff that is unnecessary gets removed by mutations. We lose stuff that is no longer useful for us. Like tails, for example, our ancestors had tails, and we don't because natural selection tends to go for simple solutions, and that's really what's made natural selection so successful, and it's also what makes science so successful too." Johnjoe McFadden is the author of Life is Simple, How Occam’s Razor Set Science Free and Shapes the Universe. He obtained his PhD at Imperial College London and went on to work on human genetic diseases and then infectious diseases, at the University of Surrey. Professor McFadden has specialised in examining the genetics of microbes such as the agents of tuberculosis and meningitis. His other books are Quantum Evolution: Life in the Multiverse, and Life on the Edge: The Coming of Age of Quantum Biology (co-authored with Jim Al-Khalili). He has published more than 100 articles in scientific journals on a wide range of subjects and lectures around the world. His present post is Associate Dean (International) and Professor of Molecular Genetics at the University of Surrey.www.surrey.ac.uk/people/johnjoe-mcfaddenhttps://johnjoemcfadden.co.ukwww.basicbooks.com/titles/johnjoe-mcfadden/life-is-simple/9781549112119www.creativeprocess.infowww.oneplanetpodcast.org
