Scientists claim they have brought the dire wolf species back from extinction after 13,000 years, thanks to genetic engineering.
On Monday, the Texas-based biotechnology and genetic engineering company Colossal Biosciences announced that three dire wolf pups were born last fall. The species became popular in modern culture thanks to their inclusion in the popular HBO series “Game of Thrones,” which inspired the company to name the young wolves Romulus, Remus, and Khaleesi, which references characters in the series.
“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 Ben Lamm said, per the New York Post. “It was once said, ‘any sufficiently advanced technology is indistinguishable from magic.’ Today, our team gets to unveil some of the magic they are working on and its broader impact on conservation.”
The team used ” somatic cell nuclear transfer” to clone high-quality cell lines, which were transferred into donor egg cells and then implanted into a surrogate, the Post reported.
Two pups were born in October 2024, while a third was born in January 2025.
Colossal made headlines last month for engineering a “woolly mouse,” which they made by injecting mammoth DNA into mice to make them grow thick coats. Per The Daily Mail, the company has a stated goal of bringing the woolly mammoth back from extinction by 2028.
