Colossal Biosciences creates genetically modified dire wolf pups

Colossal Biosciences, a company focused on de-extinction, has announced the birth of three genetically engineered dire wolf pups. This project utilized ancient DNA and artificial intelligence to reconstruct the genome of the extinct dire wolf, mapping it to its closest living relative, the gray wolf.

The process involved editing cells from modern gray wolves to create embryos, which were then carried to term by domestic dogs serving as surrogate mothers. CEO Ben Lamm indicated that more dire wolf births could occur in the near future. The company has faced skepticism, with some critics arguing that the resulting animals are essentially genetically modified gray wolves rather than true dire wolves.

Lamm dismissed these claims as a "semantic argument" that overlooks the broader scientific and potential benefits. He stated that modern gray wolves are, in essence, nature's version of genetically modified dire wolves. Colossal Biosciences is employing a similar approach for its woolly mammoth project, aiming to genetically engineer an Asian elephant with the goal of a mammoth birth in the 2030s.

The company's ambition extends beyond simply recreating extinct species. Lamm suggested that the technologies and processes developed through de-extinction efforts could yield advancements in human healthcare and the creation of programmable life models applicable to various fields. Furthermore, the project is anticipated to offer environmental benefits, such as the potential for engineered woolly mammoths to help mitigate climate change in Arctic regions.

Colossal Biosciences' work is contributing to advancements in genome engineering and developmental biology. The company plans to continue its efforts to bring back extinct species, including further work on the woolly mammoth.
