Bringing Extinct Species Back to Life | Dr. Beth Shapiro

De-extinction and genetic engineering offer transformative tools for both restoring lost species and preserving endangered ones. Evolutionary biologist Dr. Beth Shapiro explains that species classification is a human construct, noting that ancient DNA reveals complex histories of hybridization, such as the interbreeding between modern humans and Neanderthals. By leveraging synthetic biology, researchers can identify and reintroduce specific traits—like cold tolerance or disease resistance—into living relatives of extinct animals. These technologies, including gene editing and cloning, provide critical pathways for ecological restoration, such as managing invasive species or bolstering genetic diversity in threatened populations like the black-footed ferret. Ultimately, these advancements shift conservation from passive observation to active stewardship, enabling the creation of more resilient ecosystems capable of surviving rapid environmental change.
