Bringing Extinct Species Back to Life | Dr. Beth Shapiro

Dr. Beth Shapiro joins to explain what defines a species and how Neanderthal and Denisovan DNA still shows up in humans. She covers how ancient DNA and modern embryology are being used to bring back woolly mammoths, dodos, and dire wolves. The conversation also gets into the ethics of de-extinction, conservation work for endangered species like black-footed ferrets and red wolves, and how synthetic biology could make ecosystems more resilient.
