Colossal Biosciences, a Texas-based biotech startup, has successfully raised $200 million to pursue its ambitious project of bringing back the woolly mammoth. The company's valuation has soared to $10.2 billion, a sixfold increase in two years. Founded by Ben Lamm and Harvard geneticist George Church, Colossal aims to use advanced DNA editing techniques to create a woolly mammoth calf by 2028. The firm also focuses on conservation technologies for endangered species and has garnered support from high-profile investors, including the CIA-affiliated In-Q-Tel. However, some scientists express skepticism regarding the feasibility and ethics of de-extinction efforts.
