They're just "Genetically-Modified" Gray Wolf, and not actually a Dire Wolf
Colossal Biosciences' recent announcement of "resurrecting" the dire wolf has generated significant media attention, but the claim is highly misleading. The company has not indeed brought back the Aenocyon virus, the extinct dire wolf species, but instead created genetically modified gray wolves with some physical traits resembling dire wolves. Here's a breakdown of the situation:
What Was Done?
Colossal Biosciences used gene-editing technology to modify the DNA of gray wolves, which are the closest living relatives of dire wolves. They extracted ancient DNA from two fossils—a 13,000-year-old tooth and a 72,000-year-old inner ear bone—and identified genetic variants associated with dire wolf traits. The scientists made 20 edits to 14 genes in gray wolf embryos to mimic characteristics such as larger body size, wider heads, stronger jaws, and thicker fur. These embryos were implanted into surrogate dogs, resulting in three pups named Romulus, Remus, and Khaleesi.
Why These Are Not Dire Wolves
Despite the genetic modifications, these animals are not true dire wolves. Dire wolves were a distinct species genetically distant from gray wolves. Critics argue that altering gray wolf DNA to superficially resemble dire wolves does not equate to de-extinction. Vincent Lynch, a professor of biological sciences, stated that these are essentially gray wolf clones with mutations that make them look like dire wolves.34. Additionally, behaviors, ecological roles, and learned social traits of dire wolves cannot be replicated through genetic engineering alone.
The Marketing Strategy
Colossal's announcement was accompanied by a carefully orchestrated media campaign designed to generate hype. Videos showcasing "dire wolf howls" and references to popular culture (e.g., Game of Thrones) helped capture public attention. However, critics have pointed out that this approach prioritizes publicity over scientific transparency. The company has not released peer-reviewed data or detailed methodologies for public scrutiny.13.
The Red Wolf Breakthrough
Amidst the dire wolf hype, Colossal Biosciences also announced a significant achievement in conservation science: cloning critically endangered red wolves. Using cloning techniques refined during their dire wolf project, they produced four red wolf pups with improved genetic diversity. This could potentially bolster the population of red wolves, which are on the brink of extinction with fewer than 20 individuals remaining in the wild.
Bottom Line
While Colossal's work on red wolves represents a genuine contribution to conservation science, its claims about resurrecting dire wolves are exaggerated and misleading. The so-called "dire wolves" are genetically modified gray wolves—not true representations of the extinct species. This raises concerns about the public perception of de-extinction science and highlights the need for transparency and scientific rigor in such projects.
