Biotech Firm Creates Genetically Edited 'Woolly Mouse' to Advance Mammoth Revival Efforts

Colossal Biosciences has engineered mice with mammoth-like traits, marking a significant step in its controversial quest to de-extinct the woolly mammoth by 2028.

The 'woolly mouse' was developed by editing seven genes to give the rodents mammoth-like features, including long, wavy, golden fur and altered fat metabolism traits.
Colossal Biosciences aims to use similar genetic techniques to create mammoth-like Asian elephants, with a goal of producing the first calf by 2028.
Scientists used ancient mammoth DNA to identify key genes for cold adaptation and tested their viability in mice due to their short gestation period and established genetic research history.
Critics question the ecological, ethical, and financial implications of de-extinction, arguing resources might be better spent on conserving existing species and habitats.
The project has raised over $435 million and aims to develop technologies with broader applications in conservation and biotechnology, including artificial wombs and tools for endangered species preservation.
