Occasionally Extinct and Virtually Alive
Japanese researchers are currently working on cloning a mammoth, and plan to produce a fluffy new prehistoric calf within four or five years. The bucardo, an extinct subspecies of the Spanish ibex, was resurrected for a few minutes in 2009 before the clone died. ‘Frozen zoos’ now keep the cryo-preserved tissues from dozens of endangered species to hedge their bets against future extinction.
Until we have the godlike knowledge to reconstruct a genome from the base pairs on up, our resurrected zoo will be limited to the animals that we have stored away for safe keeping. Sorry, no dinosaurs, but there are at least 500 stuffed and dried passenger pigeons, 731 thylacines, and one remaining dodo specimen with soft tissue remaining.
