The journey to the woolly mouse began with the woolly mammoth. Scientists at Colossal examined more than 100 genomes of Asian elephants and woolly mammoths.

Woolly mammoths had a truncated version of a gene called TGF alpha, as well as a mutation in the keratin gene KRT27, which the scientists incorporated into woolly mouse DNA.

“The Colossal woolly mouse marks a watershed moment in our de-extinction mission,” said company CEO Ben Lamm in a statement. "By engineering multiple cold-tolerant traits from mammoth ...

The Colossal Woolly Mouse, born in October 2024, was genetically engineered to have characteristics that could eventually be used in creating a next-generation woolly mammoth embryo to be born by ...
