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.

Scientists at biotech company Colossal Biosciences were able to produce genetically modified mice, a successful feat in their ongoing conservation and de-extinction efforts.

The biotech company Colossal Biosciences has long aspired to bring back the extinct woolly mammoth, which roamed the Northern Hemisphere thousands of years ago, during the last ice age. But for now, as a step along the way, the company has come up with something decidedly less mammoth: meet the woolly mouse.

The de-extinction company Colossal Biosciences wants to bring back the woolly mammoth—starting with a very furry mouse.

Using DNA and genomics technologies, scientists have modified the mice to have longer, thicker hair and an altered metabolism expected to allow them to tolerate colder temperatures, Colossal Biosciences said.
