- Colossal Biosciences reveals new species for "de-extinction": the bluebuck
Colossal Biosciences aims to de-extinct the bluebuck, a South African antelope extinct since the 18th century, as part of its sixth de-extinction project. The company claims to have mapped bluebuck DNA and is in the final genomic editing phase, targeting a 2028 birth via surrogate. Critics question the ecological risks and authenticity of past projects like dire wolves.
