Scientists engineer mice to replicate extinct species traits

Scientists at Colossal Biosciences are genetically engineering mice to mimic traits of extinct species, like the woolly mammoth. This follows their 2021 announcement to revive the woolly mammoth and dodo bird using ancient DNA. The company aims to identify key traits of extinct animals and incorporate them into living species. CEO Ben Lamm emphasizes the goal of engineering these traits into current animals. Reactions from outside scientists are mixed, with some questioning the effectiveness of this approach for conservation. They argue that it does not truly resurrect extinct species.
