The bodies and genes of organisms can be thought of as a history book detailing how other creatures lived long ago. Richard Dawkins, inaugural Charles Simonyi Professor for the Public Understanding of Science at Oxford University, joins host Krys Boyd to discuss why the bodies of animals resemble their environments from thousands of years ago, and why sequencing these genomes offers a time machine to previous stages of evolution. His book is “The Genetic Book of the Dead: A Darwinian Reverie.”
