Colossal Biosciences Launches Bluebuck De-Extinction Project

Bluebuck De-Extinction Initiative Launched
On Thursday, Colossal Biosciences announced a project to resurrect the bluebuck, an antelope extinct in South Africa since about 1800. The plan uses gene-editing to modify roan antelope cells, create embryos, and implant them into surrogate roan mothers.
Extinction History and Antelope Decline
The bluebuck stood about four feet tall, bore 22-inch backward-curving horns, and could sprint up to 50 mph. European colonists hunted it for its pelt after arriving in the mid-1600s, driving it to extinction within roughly 150 years (1650-1800). Today, only museum specimens and historic drawings remain. Of the 90 antelope species worldwide, 55 are declining and 29 are threatened with extinction.
Key Figures and Partnerships
Beth Shapiro, Chief Science Officer, leads the scientific work; Ben Lamm, CEO and co-founder, oversees the project. Colossal is partnering with the nonprofit Advanced Conservation Strategies to identify suitable habitats and navigate regulatory steps for eventual reintroduction in southern Africa.
Technical Approach and Conservation Implications
Researchers sequenced the bluebuck genome from a tissue sample at the Swedish Museum of Natural History. Comparison with the roan antelope, its closest living relative, revealed a 3 % DNA divergence—about 18 million variants. The team narrowed functional differences to roughly 20,000 genomic regions that shape the bluebuck’s appearance. Using gene-editing, roan cells are edited, reprogrammed into induced pluripotent stem cells (iPSCs), and used to generate embryos. A gestation of about 278 days in a roan surrogate will produce the first calves, which will be raised in secure enclosures. Colossal frames the effort as a step toward broader antelope conservation, noting that iPSC technology allows testing edits without live-animal experiments and could help increase genetic diversity in threatened antelope populations. Given that 55 of the 90 extant antelope species are declining and 29 are threatened, the company hopes the platform can be adapted to bolster genetic diversity across the broader antelope clade.
Verbatim Quotes
“African antelopes have long been neglected in global conservation,” — Beth Shapiro, Chief Science Officer, Colossal Biosciences
“The bluebuck de-extinction project changes that. We’re bringing back a species that played a vital role in its ecosystem and building the scientific foundation for antelope conservation before more of its relatives are lost.” — Beth Shapiro, Chief Science Officer, Colossal Biosciences
“The other half is making sure the world is ready to protect it when it returns,” — Ben Lamm, CEO and Co-founder, Colossal Biosciences
What’s Next: Future Steps and Reintroduction Plans
The first bluebuck calves will be raised in secure enclosures while habitat suitability studies proceed. Advanced Conservation Strategies will collaborate with regional authorities to secure protected areas in southern Africa. Long-term goals include establishing self-sustaining wild populations across suitable landscapes, pending regulatory approval and habitat readiness.
