(名詞) 人工再造先前絕種的生物。

For its first project in 'de-extinction', the Revive & Restore initiative in the US aims to resurrect the North American passenger pigeon, which became extinct in 1914.

While separate attempts to revive the Tasmanian tiger, the California condor and the woolly mammoth may seem more attention-grabbing, the pigeon project could prove to be a milestone in de-extinction.

It's a process known as "de-extinction" and the genomic research that lies at the heart of it is much closer to reality today than the science fiction of dinosaurs stomping across the island laboratory depicted in the "Jurassic Park" movies.
