The Dire Wolf and the Science of Reversing Extinction

Colossal Biosciences has grand ambitions to bring back extinct species like the woolly mammoth and the dodo. But while it’s still working on those, Colossal surprised the world by announcing in April that it had created three white animals it says are dire wolves — a canine that lived in the Americas and is thought to have been slightly larger than a gray wolf. Colossal’s CEO Ben Lamm explains what it all means and how they brought the wolves into being. CNN journalist Fareed Zakaria interviews Lamm about the buzz Colossal created with its wolves and what’s coming next.
