The company that wants to see woolly mammoths roaming the earth by 2028

A team of scientists have achieved the first step in reviving the woolly mammoth: creating the woolly mouse.

It's a mouse whose genes have been edited to have the same curly, long hair that woolly mammoths had when they roamed the earth.

Colossal Biosciences is a Texas-based company looking to do the impossible, using ancient DNA for what they call "de-extinction". 

Beth Shapiro is an internationally renowned evolutionary biologist, a leader in the field of paleogenomics, and the chief science officer at Colossal Biosciences.
