Brian Cox and Robin Ince dig into de-extinction asking, could we and should we resurrect creatures of the past? They are joined by geneticist Adam Rutherford, palaeontologist Susannah Maidment and comedian/virologist Ria Lina. Extinction has played a significant role in shaping the life we see on earth today. It is estimated around 95% of species to have ever existed are already extinct - but could any of these extinctions be reversed? Our panel explore the different methods being pursued in these resurrection quests including back breeding, cloning and genetic engineering. They take a close look at the case of the woolly mammoth and the suggestion they could be returned to the arctic tundra. Some claim the mammoth is the key to ecosystem restoration, but our panel have some punchy opinions on whether this Jurassic park fantasy is even ethical.

  • This BBC podcast is supported by ads outside the uk.

  • BBC Sounds Music Radio Podcasts.

  • I'm Brian Cox.

  • I'm Robin Ince and this is the Infinite Monkey Cage.

  • Now, look out of your window.

  • If you sat at home listening to this and you know what can you see?

  • Perhaps a song thrush.

  • Maybe you can see an urban fox near your bins.

  • A magpie, or if you're lucky, two.

  • But imagine instead you saw a roaming Tyrannosaurus rex that was eating your cats.

  • Well, that's the kind of world that the boffins are trying to create.

  • Why are you adopting that tone?

  • Well, I was told to adopt that tone because apparently we're not getting enough of the Jeremy vine phone in audience.

  • And this was the kind of thing that would draw them in boffins.

  • So you might wonder what Robin is on about.

  • But today we're looking at the subject of de extinction, bringing extinct creatures back into the biosphere.

  • Basically, Jurassic Park.

  • We know how that ended.

  • With a sequel, another sequel.

  • Now, is it possible to bring species like the woolly mammoth or the dodo back from the dead?
