A company aiming to revive lost species has revealed three genetically designed wolves in the US that resemble extinct dire wolves. These wolves are seen sprinting, sleeping, and howling in their private, safe spaces.
The wolf puppies, aged 3 to 6 months, have long white hair, muscular chins, and weigh around 80 pounds. According to Giant Biology, this revelation was made on Monday.
Dire wolves, which went extinct over 10,000 years ago, were much larger than their closest living relatives today.
While independent scientists caution that this effort does not mean the dire wolves will return to North American grasslands soon, the lead scientist on the project, Beth Shapiro from Colossal, explained the process of genetically modifying blood cells from live grey wolves to create these genetically engineered puppies.
Colossal previously worked on similar projects, including creating animals resembling extinct woolly mammoths and dodos.
Although the puppies physically resemble young dire wolves, experts like Matt James, Colossal’s animal care expert, note they may lack certain behaviors vital for survival in the wilderness.
Colossal also reported cloning four red wolves using blood drawn from wild wolves to enhance genetic diversity among the endangered red wolf population.
While the technology may have broader applications for species conservation, challenges like sedating wild wolves for blood collection still remain.
Colossal’s CEO, Ben Lamm, met with officials from the US Department of Home Affairs in March to discuss the project. Despite skepticism from some scientists, interior secretary Doug Burgham praised the project as a remarkable advancement in science.
Vincent Lynch, a biologist at the University of Buffalo, emphasized that these reconstructed dire wolves cannot fully replicate the ecological functions they once performed.
