While genetic know-how has vastly increased over the past decade, the basic theoretical approach to ‘de-extinction’ remains the same. The extinct organism’s genome, sequenced from preserved remains, is first compared to that of a closely related extant species - the mammoths’ genome with that of the Asian elephant, say, or the thylacines’ with the dunnart, a living near-relative - and the functional genetic differences identified. Let’s examine both the science of resurrecting extinct species and the ethical controversies that continue to swirl around the idea of bringing long-dead creatures back to life. SIGN UP How to clone a mammoth (or a thylacine) Plus critics are saying that all the money chasing the de-extinction dream would be better spent on species facing extinction in the here and now.īut other things have shifted in the last ten years, at least in the background behind the attention-grabbing headlines - changes that perhaps tip the balance more strongly in realizing de-extinction’s potential. What hasn’t changed is enthusiasts’ wild optimism (investors have bought into the hype that thylacines could be resurrected “ in less than six years ”) … and most naysayers’ persistent pessimism. Its backers are putting serious money where their mouths are, funding projects to revive two additional species - the thylacine (or Tasmanian tiger) and the dodo. Then in a flash, the de-extinction fantasy fad faded, the science hill to climb appearing too steep to take the movement seriously.įast forward to 2023 and de-extinction is suddenly hot again. Touched off by Jurassic Park comparisons, all the talk (and it was mostly talk) was of bringing back woolly mammoths and passenger pigeons, often within ludicrously short timeframes. Ten years ago it burst into mainstream popular life : the possibility of resurrecting extinct species. Is the Genetic Literacy Project a corporate ‘front’?
