Colossal Biosciences is working on a project to preserve the dna of a large number of species, with some reports suggesting a goal of 10,000. The company claims to have made progress in de-extinction efforts, including the breeding of dire wolf-like pups, although the accuracy of these claims is disputed by some. Colossal Biosciences also plans to build a frozen biovault, potentially in dubai, to store the genetic material of endangered species.
