Colossal Biosciences Announces Plan to De-Extinct the Bluebuck Antelope, Gone Since 1800

May 1, 2026

Texas-based Colossal Biosciences announced a project to resurrect the bluebuck antelope, extinct since around 1800 and the only large African mammal species to die out in recorded history. The company extracted DNA from a Swedish museum specimen and is editing roan antelope DNA to create a bluebuck proxy, with CEO Ben Lamm anticipating birth within years. The project requires fewer genetic edits than some of Colossal's other efforts and represents the company's first foray into bovids and mainland Africa. Conservation scientists like Dr. David Mallon acknowledge the scientific interest but question whether the $555 million-funded company's resources would be better spent protecting the 29 currently endangered antelope species, including the critically endangered hirola and addax.

Colossal Biosciences' Bluebuck De-Extinction Project and Scientific Methods

▪Colossal Biosciences announced a project to resurrect the bluebuck antelope, which has been extinct for around 200 years.
▪Colossal Biosciences made 20 edits in 14 genes for the dire wolf project.
▪Colossal Biosciences has already acquired roan antelopes for the bluebuck surrogate mother purpose.
▪Colossal Biosciences began efforts on the bluebuck project in 2024.

Scientific and Conservation Community Skepticism

▪The IUCN upgraded the scimitar-horned oryx from critically endangered to endangered in 2023.
▪The scimitar-horned oryx was declared extinct in the wild in 2000 but was successfully reintroduced to Chad.
