Intro Efforts to revive the woolly mammoth, which went extinct approximately 4,000 years ago, are currently underway. Colossal Biosciences, a Texas-based startup, is at the forefront of this de-extinction endeavor. The company has raised over $235 million and aims to reintroduce a mammoth-like species by 2028. Their approach involves editing specific genes of the Asian elephant to incorporate traits characteristic of the woolly mammoth, such as adaptations for cold climates.  A significant milestone in this research was recently achieved when scientists successfully created genetically modified mice exhibiting mammoth-like traits. By altering seven genes associated with hair growth and fat metabolism, the modified mice developed thicker, curlier fur and enhanced cold resistance. This experiment serves as a proof of concept, demonstrating the potential of gene-editing techniques in recreating mammoth characteristics.  The ultimate goal of these de-extinction efforts is to reintroduce mammoth-like creatures into their former habitats, particularly the Siberian tundra. Researchers believe that reestablishing these animals could help restore the mammoth steppe ecosystem, potentially mitigating climate change effects by promoting grassland growth and preserving permafrost.  However, the feasibility and ethics of de-extinction are subjects of ongoing debate. Critics argue that resources might be better allocated to conserving existing species and habitats, emphasizing the need for careful consideration of the ecological implications of introducing engineered species into modern ecosystems.
