An antelope that Europeans hunted to extinction over 200 years ago is now the target of one of the boldest genetic engineering projects in history. Dallas-based Colossal Biosciences announced on April 30, 2026, that it plans to bring back the bluebuck, and it says it already has the science to back that promise up.

The bluebuck is now the sixth species in Colossal’s growing de-extinction portfolio, joining the woolly mammoth, dire wolf, Tasmanian tiger, dodo, and moa. With a target birth year of around 2028, the clock is officially ticking.

The Animal Colonial Hunters Wiped Out in 150 Years

The bluebuck, known scientifically as Hippotragus leucophaeus, was a medium-sized antelope with a striking silvery slate-blue coat that once grazed the open grasslands of South Africa’s southwestern Cape region. It stood roughly four feet tall at the shoulder, with backward-curving ringed horns reaching nearly two feet in length. When it ran at speeds close to 50 miles per hour, witnesses said it looked like a streak of pale blue sky cutting across the plains.

That beautiful coat became its death sentence.

European settlers pouring into the Cape from around 1650 hunted the bluebuck relentlessly, prizing its unusual pelt. Habitat loss and competition for grazing with livestock pushed the species further toward collapse. The German biologist Hinrich Lichtenstein recorded the death of the last known bluebuck in 1799 or 1800. The entire destruction took roughly 150 years. The bluebuck holds the grim distinction of being the only large African mammal known to have gone extinct in recorded history.

Today, only a small collection of museum specimens survive, including skins, skulls, and horns preserved in collections scattered across Europe. These fragments are now the foundation of a possible comeback.

How Colossal Plans to Rewrite the Bluebuck’s DNA

Colossal is not attempting a cell-by-cell recreation. The strategy is more surgical, and it relies entirely on the bluebuck’s closest living relative, the roan antelope.

Researchers extracted DNA from a bluebuck specimen housed at the Swedish Museum of Natural History and sequenced the genome with 40-fold coverage, meaning each base pair was read 40 separate times to confirm accuracy. They then mapped that genome against the roan antelope’s to find what makes the two animals genetically different. The result: the two species share more than 97% of their DNA, but that remaining 3% still represents 18 million genetic variants.

Scientists narrowed that enormous list down. “We filtered them and got to about three million variants,” said Colossal genome engineer Scott Barish. The team is now identifying which of those variants control the physical traits that defined the bluebuck, things like coat color, body size, horn shape, and its distinct white facial pattern.

Here is how the full revival process is designed to work:

• DNA extracted from a museum specimen and sequenced with 40-fold accuracy
• Key genetic differences from the roan antelope mapped and filtered down to ~3 million relevant variants
• Bluebuck-specific traits introduced into roan antelope cells through genome editing
• Edited cells used to create an embryo via in vitro fertilization
• A roan antelope surrogate carries the embryo through a nine-month gestation period
• The surrogate gives birth to a bluebuck calf

CEO Ben Lamm told Axios the company is targeting a birth year of “2028-ish.” Colossal has already acquired roan antelopes for use as surrogates and is now deep into the genome editing phase.

The Lab Breakthroughs Already Changing Antelope Science

The bluebuck project has already produced real scientific firsts that go well beyond what any lab has achieved before in antelope research.

The Colossal team created the world’s first induced pluripotent stem cells, known as iPSCs, from roan antelope. These are adult cells that have been reprogrammed back to a stem-cell state, giving them the ability to develop into virtually any type of body tissue. This lets scientists test the effects of genetic edits in cells before any live animal is ever involved.

The team also completed the world’s first successful ovum pickup procedures in two antelope species: the roan antelope and the scimitar-horned oryx. Previously, collecting viable eggs from wild antelope species at any reliable scale was considered nearly impossible. That barrier is now broken.

These advances are not just tools for the bluebuck. They could directly benefit the dozens of antelope species already teetering on the edge. According to the International Union for Conservation of Nature, 29 of the world’s roughly 90 antelope species currently face extinction, with populations declining in 62 percent of all species.

“African antelopes have long been neglected in global conservation,” said Dr. Beth Shapiro, Colossal’s Chief Science Officer. “We’re building the scientific foundation for antelope conservation before more of its relatives are lost.”

The Debate: Bold Science or a Conservation Distraction?

Not everyone is celebrating this announcement.

Critics have raised two pointed objections. The first is about scientific honesty. Following Colossal’s dire wolf announcement in 2025, Dusko Ilic, a professor of stem cell science at King’s College London, described the animals as “synthetic proxies” designed to mimic physical traits. He called the broader concept of de-extinction an “illusion,” arguing that learned behaviors, ecological instincts, and true species identity cannot be recreated through gene editing. Some scientists have reinforced that view, noting the company’s own chief scientist acknowledged the dire wolves are essentially gray wolves with targeted genetic edits.

The second concern is about where the money goes. Paul and Anne Ehrlich of the Yale School of Environment’s Center for Conservation Biology have argued that “even if reviving extinct species is practical, it’s an awful idea,” suggesting resources are better spent on living species facing urgent threats right now.

David Mallon, visiting professor at Manchester Metropolitan University and honorary chair of the IUCN’s Antelopes Specialist Group, offered a more measured view. He called the project “an extremely interesting development” while noting that conservation of living antelope species must remain the immediate priority. “Each such announcement creates a halo of awareness about biodiversity loss,” he said, “but conservation actions must remain a priority.”

Lamm has answered these criticisms head-on. “Conservation as currently practiced is not winning. We are losing species faster than our existing toolkit can address,” he said. He argues de-extinction does not compete with conservation. It expands what conservation can do.

What a Returned Bluebuck Would Mean for South Africa

Getting the science right is only one part of what Colossal says it needs to succeed. The ecological and political groundwork has to happen in parallel.

The company has partnered with the Endangered Wildlife Trust in South Africa and Advanced Conservation Strategies, which is actively evaluating potential reintroduction sites and the regulatory pathways required under South African environmental law. No specific location has been confirmed yet.

Lamm was candid about the size of the challenge waiting after the lab work is done. “Bringing the bluebuck back is only half the work,” he said. “The other half is making sure the world is ready to protect it when it returns.” He stressed that legal protections would need to extend across the broader southern African landscape, not just inside a single reserve.

Dr. Yoshan Moodley, Professor of Zoology at the University of Venda in South Africa, pointed to a wider scientific benefit. “Knowledge of the bluebuck’s evolutionary adaptations could help the conservation of other rare and specialized African ungulates,” he said.

What makes this story extraordinary is not just the technology. It is the moral question underneath all of it. The bluebuck survived for at least 400,000 years on this planet, outlasting ice ages and the rise and fall of civilizations, only to be wiped out in 150 years of colonial hunting. The fact that humanity now has the tools to potentially undo that loss, and is seriously debating whether to use them, speaks to both how far science has come and how heavy that history still is. The bluebuck may or may not roam South Africa’s grasslands again. But the conversation happening right now in labs, boardrooms, and conservation circles around the world is one worth every reader paying close attention to.
