Hoping to revive mammoths, scientists create 'woolly mice'

A woolly mouse, a breed created by scientists using genetic engineering. The development is a first step toward reviving a version of the extinct woolly mammoth.

Hoping to bring the giant, ancient animal back from extinction, scientists have created a far smaller woolly creature. Woolly mice have some of the key traits of mammoths, including their thick, hairy coat.
