de-extinction
The woolly mammoth (Mammuthus primigenius)—represented here by a replica in a Canadian museum—is an example of an extinct species that someday could be resurrected through de-extinction.
De-extinction technologies offer significant potential for the conservation of endangered species by providing advanced tools to manage and restore biological diversity.1
While these methods are often associated with resurrecting extinct animals, the underlying techniques are highly applicable to living species facing the threat of extinction:
- Genetic Restoration: Researchers can use the reconstruction of extinct or historical genes to restore lost genetic diversity within threatened species or subspecies, potentially increasing their resilience to environmental changes.1
- Advanced Reproductive Technologies: Tools such as in vitro fertilization and somatic cell nuclear transfer (SCNT), originally developed for cloning, can be adapted to assist in the breeding and population recovery of critically endangered animals.1
- Stem Cell Applications: The use of stem cells to create gametes (sperm and eggs) offers a pathway to support reproduction in species where natural breeding is no longer viable or possible.1
By fueling progress in genetics and developmental biology, these innovations provide scientists with a broader toolkit to address the urgent needs of biodiversity conservation.1
