US company Colossal Biosciences has announced the creation of a "woolly mouse"—a laboratory mouse with a series of genetic modifications that lead to a woolly coat. The company claims this is the first step toward "de-extincting" the woolly mammoth.

Scientists at Colossal Biosciences have achieved a milestone to resurrecting the woolly mammoth: laboratory mice with thick, curly coats.

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.

It will take a lot more genetic science than a few tweaks to hair length to make a mammoth from its closest living relative, the Asian elephant.
