"Our team took DNA from a 13,000-year-old tooth and a 72,000-year-old skull and made healthy dire wolf puppies," Colossal CEO ...

The revived dire wolves are growing, as Colossal Biosciences has shared an update on the three pups that were brought back ...

The Colossal team claims to have used a 72,000-year-old dire wolf skull and a 13,000-year-old tooth to isolate real dire wolf genome sequences, then map some of that genome onto gray wolf DNA.

The de-extinction process begins with ancient DNA. In the case of the dire wolf project, Colossal scientists were working from two fossils, a 13,000-year-old tooth and a 72,000-year-old skull.

Colossal says its dire wolf work had key differences. Scientists first analyzed the genome of the dire wolves contained in the ancient tooth and skull.

“So what Colossal has produced is a grey wolf, but it has some dire wolf-like characteristics, like a larger skull and white fur,” Dr. Nic Rawlence said. “It’s a hybrid.” ...
