Summary
Scientists around the world are trying to figure out how to mitigate the potentially disastrous impacts of climate change.
Among the innovative ideas? De-extinction.
“De-extinction is a scientific movement that’s aiming to recreate close versions of extinct species,” said Britt Wray, the author of Rise of the Necrofauna: The Science, Ethics, and Risks of De-Extinction.
Wray says the idea is to create close facsimiles of “keystone species,” or animals that had a profound impact on their ecosystems.
As you can imagine, de-extinction brings up a lot of questions, including:
How on earth do you replicate an ancient zebra-horse?
What happens when countries can create patents for lab-grown animals?
And why would we want woolly mammoths to roam the arctic again?
Wray tackles all those questions, and more, on the latest episode of Nerdette.

| 0:26.0 | insane scientific discoveries that seem like they could just be science fiction. |
| 0:31.2 | Designer babies, computers in your clothes, hyper-specific targeted ads |
| 0:35.3 | delivered straight to your brain. But hey, did you know scientists right now are trying to figure |
| 0:42.0 | out how to bring back animals that haven't existed on this planet for thousands of years. |
| 0:47.0 | That is what we are talking about today on Nurdett. It's called de-extinction. |
| 0:55.0 | And it turns out that animals that lived hundreds of thousands of years ago could help save the future of the planet. |
| 1:10.3 | As I'm sure you can imagine, the idea of de-extinction goes really quickly from potentially awesome discovery to maybe |
