Colossal's De-extinction Dreams: Have They Delivered?
The hype surrounding Colossal Biosciences' de-extinction claims has been nothing short of meteoric. In 2025, the company's billionaire CEO Ben Lamm unveiled plans to bring back the dire wolf and other extinct species, sparking international headlines and public fervour. Enthusiastic profiles in Time magazine and the New Yorker declared "the dire wolf is back", with Colossal's CEO confidently predicting a fan favourite.
However, beneath the surface of Colossal's de-extinction announcements lies a more nuanced reality. The company has made 20 edits to the DNA of grey wolves, creating animals that do not substantially differ from those roaming North America today. This begs the question: have Colossal truly brought back anything, or are they simply engineering poor copies?
Leading experts in the field have voiced concerns about Colossal's methods, warning against spreading misinformation and undermining trust in science. "Extinction is still for ever," says Nic Rawlence, director of the palaeogenetics laboratory at the University of Otago. "Rather than true de-extinction, Colossal's attempts are genetically engineered poor copies at best."
The company's chief scientist Beth Shapiro acknowledges that it's impossible to bring something back that is identical to a species that used to be alive. Instead, Colossal's animals are grey wolves with 20 edits inserted through genetic engineering.
Critics argue that the hype surrounding de-extinction technology can weaken trust in science and distract from more pressing conservation issues. "De-extinction technology could be a useful conservation tool for living species," says Rawlence, "but it won't replace unsexy grunt work."
While Colossal's harshest critics acknowledge the potential of gene editing to save species caught in genetic bottlenecks, they stress that traditional conservation efforts – controlling predators, protecting ecosystems and restoring habitats – remain essential.
As Colossal pushes forward with its ambitious plans, including the unveiling of a genetically modified Asian elephant adapted to live at -40C (-40F), some scientists are left wondering: have the promises delivered? Have Colossal truly brought back anything, or is it just a case of Silicon Valley showmanship and entrepreneurial drive?
One thing is certain – the debate over de-extinction technology is far from over.
