Scientists Finally Learned How a Tiny Mouse Survives Near the Andes Death Zone at 7,000 Meters - ZME Science
Researchers have discovered how the Andean leaf-eared mouse survives at extreme altitudes of over 6,700 meters, far beyond the previously assumed limit for mammals. The study reveals that these mice evolved unique physiological adaptations, including the ability to detoxify plant compounds, to thrive in oxygen-starved, freezing environments.
Why it matters
Understanding these biological adaptations provides new insights into the limits of mammalian life and evolutionary resilience in extreme environments.
Mammals shouldn’t permanently live much above 5,500 meters (18,000 feet). Above this altitude, the combination of oxygen-starved air, freezing temperatures, scarce food, and relentless winds was thought to make long-term life nearly impossible.
