Scientists Just Created a ‘Woolly Mouse’ With Mammoth-Like Fur
The de-extinction company Colossal Biosciences wants to bring back the woolly mammoth—starting with a very furry mouse.
Some of the mice also had edits to a gene involved in the metabolism of fatty acids, which should change how the animals store fat—another key difference between mammoths and Asian elephants. There’s 200 million years of evolutionary divergence between them, and that wouldn’t make any sense,” from either a scientific or ethical perspective, says Beth Shapiro, chief science officer at Colossal. Lynch points out that lots of the standard scientific processes for gene editing and implanting cells have been developed on mouse models and may be more difficult in other species.
