Once hunted into extinction, the bluebuck is now at the centre of one of the most ambitious conservation science projects the world has ever seen.

Johannesburg, South Africa (06 May 2026) – The bluebuck antelope, the first recorded African mammal driven to extinction, is officially at the centre of a groundbreaking de-extinction project announced by Colossal Biosciences… and it’s putting South Africa back into one of the biggest scientific conversations on the planet.

The bluebuck, or Hippotragus leucophaeus, once roamed the Western Cape with its striking silvery-blue coat and unmistakable beauty. A grassland grazer and natural seed spreader, the animal played an important role in shaping its ecosystem long before humans changed the landscape forever.

But by the early 1800s, it was gone.

“The bluebuck (Hippotragus leucophaeus) was a striking silvery, slate-blue antelope native to South Africa’s Western Cape. As a grassland grazer and seed spreader, it helped shape its ecosystem. By 1800, after climate shifts, habitat conversion, farming, and overhunting, it was gone,” Colossal Biosciences stated in their announcement.

“We don’t love that ending. So we’re rewriting it.”

Colossal became global news in 2024 after bringing back the first-ever woolly mouse and then in 2025, after announcing the return of the ‘Dire Wolf‘. Three pups were born as part of that controversial project: two males, Romulus and Remus and a female named Khaleesi. Scientists and conservationists debated whether the animals represented a true return of the extinct species or highly accurate genetic proxies, but regardless of the criticism, the achievement changed the conversation around what science may one day be capable of.

Now, that same technology is being pointed toward a species that once belonged to South Africa.

The company explains that advances in genomics now allow researchers to reconstruct the bluebuck’s DNA using high-quality reference genomes as a blueprint. It’s science that feels almost impossible to comprehend but the implications stretch far beyond one animal.

The reproductive side of the project is equally remarkable. Researchers are developing assisted reproduction technologies for antelope species, including ovum pick-up procedures, IVF, embryo culture, embryo freezing and embryo transfer. Many of these techniques have reportedly never been achieved in antelope before. Eventually, the team plans to use a genetic surrogate to help rebuild the species. The bluebuck’s closest living relatives are the roan and sable antelope, with the roan antelope expected to serve as the genomic surrogate for the first bluebuck embryos.

And while the phrase “de-extinction” sounds like something pulled straight from a science-fiction movie, the bigger picture here is conservation.

Africa’s antelope populations are increasingly under pressure from habitat fragmentation, shrinking wild spaces and declining genetic diversity. Those challenges are isolating species and making long-term survival harder across the continent. Colossal says the tools being developed through this project could eventually strengthen breeding programmes, support reintroductions and accelerate conservation efforts for antelope species everywhere.

This isn’t just about bringing back an animal humans lost centuries ago. It’s about developing technology that could help protect species we still have time to save. There’s something deeply hopeful about that.

For so long, extinction has felt final. Permanent. A full stop at the end of a story humanity helped write. But projects like this challenge that thinking entirely. They ask bigger questions about responsibility, restoration and whether science can help repair pieces of the natural world we once believed were gone forever.
