The Bluebuck: A Forgotten Species, Revived by Colossal Biosciences
The Bluebuck, a once-thriving antelope species from South Africa's southern Cape, has been largely forgotten due to its limited historical record. With no photographs, moving images, or audio recordings of the animal, its existence is known only through a handful of skins, horns, sketches, and written descriptions. Despite its obscurity, the Bluebuck has been chosen by Colossal Biosciences as a de-extinction target, marking a significant effort to bring back a species that played a vital role in its ecosystem.
The Bluebuck's story is one of quiet extinction. It lived for thousands of years on the grasslands of the southern Cape without entering the written record until German astronomer Peter Kolbe described it in 1719 as a 'blue goat'. By the time naturalists began studying it, the species was already fading, and it was scientifically named in 1766, only to go extinct 34 years later. The rarity of the Bluebuck's existence is further emphasized by the fact that even the physical evidence is contested, with only a few verified pieces of skin remaining.
Genomic analysis of surviving specimens reveals that the Bluebuck persisted for thousands of years at low population size, and its extinction was primarily due to colonial-era human impact. The conversion of grassland habitat to farmland and the displacement of herds led to the species' rapid disappearance within decades. This pattern of quiet and swift extinction is common among many plants and animals today, often generating no headlines and leaving little cultural record.
Colossal Biosciences has chosen the Bluebuck as an entry point into a group of animals that conservation has underserved. As the company's first effort focused on antelopes, the Bluebuck project carries significant implications for the 29 antelope species currently threatened with extinction. Beth Shapiro, chief science officer at Colossal Biosciences, emphasizes the importance of bringing back a species that played a vital role in its ecosystem and building the scientific foundation for antelope conservation.
The Bluebuck's story is a fascinating one, holding two levels of significance. On one hand, it represents an animal lost and now being reconstructed from fragments. On the other, it highlights the ongoing challenges faced by living antelope species and the potential tools that studying the Bluebuck could provide for their conservation. Colossal's approach to de-extinction, with a focus on antelopes, is a bold move that could have far-reaching implications for the future of these vulnerable species.
