Second, the re-introduction of the species to the environment has to be carefully assessed. De‐extinction, the process of resurrecting extinct species, is in an early stage of scientific implementation. It’s a two-step process: first, the extinct species needs to be revived from the dead.
"de-extinction" refers to the process of resurrecting extinct species by genetic methods. Although the de-extinction of the Passenger Pigeon will likely take decades, de-extinction research is already generating foundational science that could transform bird conservation.
We review and discuss the application of the existing evolutionary conservation framework to potential de‐extinction projects. De-extinction is a very new science, and presently has very little experimental success to be regarded as an established scientific method. This process is also seen in de-extinction, where the charismatic animals used to support ‘cool,’ new de-extinction technologies include the woolly mammoth, the passenger pigeon, and the saber-toothed cat. De-extinction requires an in-depth study of the biophysical conditions where the species can live and reproduce in relation to other species, including humans and ability to adapt to environmental changes. However, its potential to contribute effectively to biodiversity conservation remains unexplored, especially from an evolutionary perspective. Methods of de-Extinction. De-extinction refers to any process by which an extinct organism is revived or brought back to life, or a species that closely resembles an extinct species is recreated. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. De-extinction is the process of creating an organism which is or greatly resembles a member of an extinct species. As lead scientist of “The Great Passenger Pigeon Comeback” project, Novak adopted a holistic approach to de-extinction.
