De-extinction, or resurrection biology, reverses plant and animal extinctions by creating new versions of previously lost species. The eggs can then be further manipulated to develop into full-fledged embryos. The history of putting species back after theyve gone extinct in the wild is fraught with difficulty, says conservation biologist Stuart Pimm of Duke University. Why invest millions of dollars in bringing a handful of species back from the dead, when there are millions still waiting to be discovered, described, and protected?, De-extinction advocates counter that the cloning and genomic engineering technologies being developed for de-extinction could also help preserve endangered species, especially ones that dont breed easily in captivity.
