Explore the fascinating science of de-extinction in this 54-minute lecture by evolutionary biologist Beth Shapiro. Delve into the controversial process of bringing extinct species back to life, from selecting candidates for resurrection to sequencing genomes and managing revived populations. Learn about ancient DNA research, genetic diversity, and cutting-edge techniques like CRISPR-Cas9. Examine the feasibility and ethical implications of resurrecting mammoths, passenger pigeons, and other extinct animals. Discuss the potential ecological impacts of de-extinction projects and their role in conservation efforts. Consider the challenges of recreating extinct species beyond just their genomes, including differences in appearance and behavior. Gain insights into ongoing de-extinction initiatives and their potential to impact ecosystems, such as the role of herbivores in climate change mitigation.
