While global attention has focused on Colossal Biosciences’ groundbreaking revival of dire wolves, a parallel conservation triumph has emerged from the same research: the successful cloning of critically endangered red wolves (Canis rufus). This development could prove crucial for a species on the brink of disappearing forever.
With fewer than 20 red wolves remaining in North America, they hold the unfortunate distinction of being the world’s most endangered canid. Once abundant across most of eastern North America, red wolves had nearly vanished by 1960. Despite protection under the Endangered Species Act and a captive breeding program that briefly boosted wild populations to more than 120 wolves, their numbers crashed when conservation efforts were halted in 2015.
Using the same technologies developed for dire wolf de-extinction, Colossal has produced four healthy red wolf pups from two litters, representing three different genetic founder lines. The female pup has been named Hope, while the three males are called Blaze, Cinder, and Ash—names reflecting optimism for the species’ future.
“The company’s work to combat extinction of the Red Wolf creates hope for so many other critically endangered species fighting for survival,” says Aurelia Skipwith Giacometto, former Director of the US Fish and Wildlife Service and conservation advisor to Colossal.
The red wolf cloning used Colossal’s novel method of isolating endothelial progenitor cells (EPCs) following a standard blood draw—a non-invasive technique developed during the dire wolf work. This approach allows collection of genetic material during routine veterinary procedures without additional stress to the animals. The cells were then used for somatic cell nuclear transfer, embryo development, and transfer to surrogate mothers.
A critical conservation challenge for red wolves has been their limited genetic diversity. All existing red wolves descend from only 12 founder individuals, creating a severe genetic bottleneck that threatens the species’ long-term viability. Adding Colossal’s red wolves to the captive breeding population would increase the founding lineages by 25%, potentially revitalizing the species’ genetic health.
The red wolf effort also encompasses research into “ghost wolves”—unique canids found only on the Gulf Coast of Texas and Louisiana that carry genetic material from red wolves. Dr. Kristin Brzeski of Michigan Technological University, who co-leads the Gulf Coast Canine Project, explains: “The technology and understanding developed through Colossal’s red ‘ghost’ wolf project has now unlocked additional genetic diversity and red wolf ancestry that can be a resource to create a genetic rescue program for the red wolf population.”
Mike Phillips, Director of the Turner Endangered Species Fund, notes the broader implications: “Perfecting genomic tools to integrate ‘ghost alleles’ from Gulf Coast canids would increase red wolf genetic diversity and generate knowledge for recovering other imperiled species, like the bolson tortoise, that are compromised by restricted ranges and reduced genetic diversity.”
Colossal’s long-term goal is for their red wolves to be rewilded through current US conservation efforts in collaboration with the US government. Research suggests that restoring wolves to ecosystems can have significant positive impacts on factors that drive climate change and support biodiversity.
“Our world is grappling with a biodiversity crisis that demands groundbreaking solutions to slow the global loss of species,” says Dr. Kristin Brzeski. “The tools Colossal has developed for de-extinction will radically improve conservation practitioners’ abilities to ensure population redundancy and genetic viability for dwindling species, thus changing how we conserve endangered wildlife.”
For the red wolf, Colossal’s innovations may represent the difference between extinction and recovery. By combining cutting-edge genetic technologies with traditional conservation approaches, there’s renewed hope for North America’s unique native wolf—a species that might otherwise have followed the dire wolf into extinction.
As Suzanne Asha Stone, Director of the International Wildlife Coexistence Network, reflects: “We owe it to the amazing Red Wolf to devote ourselves to their full and humane recovery. I’m excited to see this iconic American species benefit from new and exciting technologies that Colossal is developing to reverse and prevent extinctions.”
