Researchers claim breakthrough in step toward making mammoths 'de-extinct' US scientists have created a "woolly" mouse by expressing genetic information gathered from woolly mammoths and elephants, which they see as a step toward bringing the extinct species back to life.

Colossal Biosciences has altered several genes in mice to make them look more mammoth-like, but the company is far from its goal of fully resurrecting woolly mammoths by 2028

Woolly mammoths roamed the frozen tundras of Europe, Asia and North America until they went extinct around 4,000 years ago. Colossal made a splash in 2021 when it unveiled an ambitious plan to revive the woolly mammoth and later the dodo bird.

On March 4th Colossal Biosciences, a company trying to revive long-gone species, announced that they had genetically engineered a Mus musculus to have qualities of the extinct Mammuthus primigenius. Instead of earth-shaking stature or enormous tusks,
