Part 4/11:
As scientists aim to resurrect extinct species, the creation of the woolly mouse—genetically modified to exhibit traits reminiscent of the woolly mammoth—marks significant progress in this field. Researchers at Colossal Biosciences are working to understand cold climate adaptations through these mice, hoping to lead to the reintroduction of actual woolly mammoths by 2028. This endeavor raises ethical questions about the feasibility and consequences of de-extinction but represents a pivotal step in genetic engineering.
