High in the Andes, where the air itself becomes an adversary, a small mouse has quietly solved problems that defeat far larger creatures. Researchers at the University of Oklahoma have uncovered how the Andean leaf-eared mouse endures elevations above 6,000 meters year-round — elevations that push elite mountaineers to their limits within a single day — through enhanced heat generation and a remarkable capacity to process plant toxins. What deepens the mystery is that these mice remain genetically nearly identical to their sea-level relatives, suggesting that the force of natural selection sha
