Physics of the Future: Bringing Back the Extinct

What I’ve learned from reading Physics of the Future by Michio Kaku:

This is my last post (as far as I know) about genetics. I’m getting a little tired of it, though it is interesting. But I couldn’t resist commenting on this idea: using genetics to bring back extinct animals.

Basically, it could be possible. Kaku suggests that we’d do it not with cloning but with altering the genes of an existing creature. It could also be possible to mess with something’s genes and make an entirely new animal.

Would we want this? Think about all the trouble invasive species have caused. (A lot). But bringing back extinct animals to zoos or their former natural habitats wouldn’t technically make them invasive. I think zoos and parks would get a lot more visitors if they had formerly extinct animals on display.
