Colossal Bioscience says it has “de-extincted” the dire wolf, but other scientists disagree and say more important conservation science is being lost in all the hype

Colossal is working with several Indigenous partners who might take in the dire wolves and other extinct animals the company is trying to bring back.

Colossal Biosciences made a surprise announcement Monday, claiming it had brought the dire wolf back from the dead, achieving the biotech company’s first successful de-extinction. But some scientists say that while the wolves’ existence is an impressive feat,
