From NBC News Cosmic Log:
If scientists can use genetic engineering to bring back the woolly mammoth, should they do it? How about the passenger pigeon? Or the western black rhino? Do we humans have a responsibility to restore at least some of the species that our ancestors wiped out? And if we bring them back, will they really be the same?
Such questions are the focus of TEDxDeExtinction, a public forum that's being presented on Friday from 8 a.m. to 5 p.m. ET at National Geographic's Washington headquarters. You can watch the whole thing online via LivestreamTEDx and National Geographic's De-Extinction website, which also has loads of articles and resources on the issue. The event has been organized by Revive & Restore, a nonprofit clearinghouse for worldwide de-extinction work that's under the aegis of the Long Now Foundation in San Francisco.
"De-extinction"? What's that?
"It's using new technologies like cloning and genome sequencing to reconstruct a species that went extinct," science writer Carl Zimmer explained. Zimmer's talk at Friday's TEDx event will help set the scene for the de-extinction debate, and he's also written a cover story on the topic for National Geographic's April issue.
