Dr. Beth Shapiro, PhD, is an evolutionary biologist and Chief Science Officer at Colossal Biosciences. Her work focuses on de-extinction and wildlife conservation efforts. We discuss genetic differences among humans, and how ancient DNA and modern embryology are being used to de-extinct and protect woolly mammoths, dodo birds, and dire wolves, as well as to help conserve endangered species. We also explore the ethical implications of de-extinction and how synthetic biology can help build a more bio diverse and resilient world.
