The Race to Revive Extinct Animals: Dream or Reality?

Bringing extinct animals back to life is not just a fantasy anymore. Thanks to advancements in genetic engineering and synthetic biology, companies like Colossal Biosciences are working on resurrecting creatures like the woolly mammoth and dodo. Recently, they secured a massive $200 million investment, totaling $435 million. This money is fueling their ambition to recreate animals we only know from history books within the next decade. Funding for such projects is attracting attention from conservationists. They believe these efforts can help protect current species and ecosystems. However, not everyone is convinced. Critics argue that this money could be better spent on preserving existing wildlife. They also worry about the ethical issues and potential threats to current ecosystems. Is cloning the answer? Cloning can create near-identical genetic copies, but it's not feasible for long-extinct species. Traditional selective breeding, like Grazelands Rewilding's project to revive the aurochs, has shown promise. They've created a breed called tauros that is 99% genetically similar to the extinct aurochs. Colossal's approach involves editing the genome of a living relative. They aim to create hybrids that mimic extinct species. For the mammoth, they're using the Asian elephant. They've made significant progress, such as creating elephant stem cells that can turn into various types of cells. But how realistic is reviving these species? The mammoth's habitat, the Arctic, is warming too fast for elephants to make a significant impact. Other projects, like bringing back the Tasmanian tiger and dodo, face challenges. Despite these hurdles, experts see value in using biotech to protect endangered species.
