Can scientists really resurrect the dodo? Inside the company that says they can

Colossal Biosciences' CEO says its work follows a moral obligation' while critics say it's tech bro' hype that could undermine conservation

Can and should we resurrect animal species that have been extinct for thousands of years? Such weighty, existential questions were once the preserve of science fiction but are now being played out within an unassuming brick building in a Dallas business park.

Colossal Biosciences, valued at $10.2bn after raising hundreds of millions of dollars in funding from investors including celebrities spanning from Tiger Woods to Paris Hilton, has provoked a stampede of acclaim as well as denunciation after announcing last year it had made the dire wolf, a species lost from the world for more than 10,000 years, de-extinct" via the birth of three new pups.
