Scientists aiming to bring back woolly mammoth create woolly mice


Genetically modified mice have traits geared towards cold tolerance, in step towards modifying elephants

Scientists at the US biotechnology company Colossal Biosciences plan to “de-extinct” the prehistoric pachyderms by genetically modifying Asian elephants to give them woolly mammoth traits. Ben Lamm, co-founder and chief executive of Colossal, said the team had been studying ancient mammoth genomes and comparing them with those of Asian elephants to understand how they differ and had already begun genome-editing cells of the latter. Robin Lovell-Badge, head of stem cell biology and developmental genetics at the Francis Crick Institute in London, who was not involved in the work, praised the technical aspects of the study.
