14 extinct animals that could be resurrected

Woolly mammoth

Early in 2011, Japanese scientists announced that they planned to clone a woolly mammoth within five years. The clock is ticking, but with a little luck these ice age behemoths may soon become the first inhabitants of the world's first zoo for extinct animals.

Mammoths make particularly good candidates for resurrection because they went extinct so recently and because many intact specimens have been found frozen in the Arctic tundra. Furthermore, because mammoths are so closely related to a living species — elephants — scientists may be able to simplify the process by having a living elephant give birth to a mammoth.
