Scientists Create Woolly Mice. Next up is the Mammoth That Went Extinct Around 4,000 Years Ago Animals belonging to past periods always invite fascination, like dinosaurs and woolly mammoths. A company went one step ahead in its fascination when it decided to resurrect some of these beings,

The mice were created by Colossal Biosciences, which edits DNA for species conservation, and has been working to bring back the woolly mammoth since 2021.

Colossal Biosciences genetically engineered a ‘woolly mouse’ with mammoth traits. The milestone could inform human gene therapy.

Scientists working to bring back the woolly mammoth have created genetically engineered mice that they say have several features of the extinct ice age giant.

Dallas-based Colossal is one step closer to bringing back the woolly mammoth.

Colossal Biosciences has engineered mice with mammoth-like traits for living in cold climates. These mice have wavy, golden coats and could be plumper.

While the Colossal Laboratories and Biosciences project to bring back extinct species has been compared to “Jurassic Park”, it has started at a much smaller scale than a T. Rex: woolly mammoth mice.
