Overview

• 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.
