Biotech's Journey to the Past

The company Colossal Biosciences, which has already 'revived' the species of dire wolves that went extinct 10,000 years ago, plans to replicate this success with other extinct animals. The goal is to restore disrupted ecosystems and raise public awareness of conservation. However, such projects raise concerns among scientists and bioethicists. Genes often perform several functions simultaneously, and even minor DNA changes can lead to unexpected consequences – from health issues to the emergence of aggressive and environmentally-resistant organisms.
