Earlier this month an American bioscience company revealed their genetically engineered woolly mouse, which they described as a step towards bringing the woolly Mammoth back to life. Colossal Biosciences say they edited the genes of mice to replicate the same long, curly hair of Mammoths with the hope of transferring this science to Asian Elephants. RNZ understands Colossal Biosciences also has its sights on the Moa. But as Victor Waters explains, experts here say bringing back the Moa is a no go.
