Researchers have made significant progress in reviving the extinct Tasmanian tiger, or thylacine, using genome sequencing from a newly discovered specimen in a Melbourne museum. The preserved head contained long RNA molecules vital for reconstructing the thylacine's genome. Colossal, a Texas-based biotech firm, is spearheading this de-extinction effort, which aims to create a living thylacine within a few years. Critics raise ethical concerns about prioritizing extinct species over living ones, while the project continues to attract global attention and funding for its ambitious goals.
