TED Talks Daily The genetic rescue of Earth’s endangered species | Ryan Phelan
Sep 22, 2021
Ryan Phelan, a biotech entrepreneur and conservation innovator, dives into groundbreaking genetic rescue efforts aimed at saving endangered species. She highlights the cloning of Elizabeth Ann, a black-footed ferret, to improve genetic diversity and tackle biodiversity loss. Phelan discusses the powerful potential of genomic sequencing and the restoration of species like the American chestnut tree through genetic engineering. She argues for embracing the 'intended consequences' of these technologies to help restore Earth's balance and biodiversity.

Episode notes
Elizabeth Ann: A Genetic Hope
- Elizabeth Ann, a cloned black-footed ferret, embodies hope for her endangered species.
- She possesses three times more genetic diversity than any living ferret, promising greater resilience.
Przewalski's Horses and Genetic Rescue
- Przewalski's horses, the last true wild horse species, face inbreeding risks.
- Genetic rescue offers a way to increase their survival by adding variation.
Essential Genetic Rescue Tools
- Genomic sequencing and biobanking are crucial for genetic rescue efforts.
- These tools, though essential, are not widely adopted in conservation.
