The Latest Breaking News from Colossal Biosciences

If it looks like a dire wolf, is it a dire wolf? How to define a species is a scientific and philosophical question

Biotech company Colossal Biosciences made headlines in April 2025 after claiming it had “successfully restored … the dire wolf to its rightful place in the ecosystem.” Three wolf pups – Romulus, Remus and Khaleesi – were born through this de-extinction project.

'Our animals are gray wolves': Colossal didn't de-extinct dire wolves, chief scientist clarifies

Colossal Biosciences' chief scientist has clarified that its "dire wolves" are just genetically modified gray wolves following a backlash to the "de-extinction" label it put on them.

Colossal's de-extinction campaign is built on a semantic house of cards with shoddy foundations — and the consequences are dire

"Dire wolves" created by Colossal Biosciences were pegged as "the first animals in history to be brought back from extinction." But that all depends on your definition of de-extinction — and Colossal's definition isn't the same as everyone else's.

‘De-extinction’ of dire wolves promotes false hope: technology can’t undo extinction

If we must bring back extinct species, let’s focus on the giant herbivores

The American genetic engineering firm Colossal Biosciences recently announced to much fanfare it had “de-extincted” the dire wolf, a canine species that was wiped out around 10,000 years ago. However, the three animals it presented are actually modern grey wolves with some genetic modifications.

Why ‘de-extinct’ dire wolves are a Trojan horse to hide humanity’s destruction of nature

With wildlife populations globally 73% smaller on average than in 1970 and large mammals missing from much of the world, surely there’s never been a better time to “de-extinct” species? US biotech company Colossal Biosciences Inc claimed to do just that recently by resurrecting the dire wolf from Game of…
