What if extinction isn't the end? What if we could take animals from the past — mammoths, goats, anything that's gone extinct — and bring them back to life in the present day? There's a new movement afoot among scientists that thinks we could do it, thanks to new breakthroughs in DNA sequencing. Of course, it won't be easy, and there are plenty of skeptics who think it's impossible. In the first episode of The Big Future, Ellis Hamburger breaks down what we know, what we're still figuring out, and what it means for the mammoths of the future.
When you're done watching, you can read our report on deextinction, or learn more about the scientists who are trying to make it happen. And if you like what you see, check back next week when we'll have another video about what we'll need to colonize Mars.
