The Andean mountain mouse, known as 'ratón orejudo andino,' inhabits altitudes up to 6,700 meters in the Andes of Chile and Argentina, where temperatures drop below zero. Researchers discovered that these mice have developed unique physiological adaptations to survive extreme cold and low oxygen levels. A study published in Science revealed that high-altitude mice consume more oxygen, exhibit increased muscle tremors to generate additional heat, and have blood cells capable of managing carbon dioxide more effectively, reducing hyperventilation risks. These findings challenge previous assumptions that such extreme environments were uninhabitable for mammals, highlighting the mouse's evolutionary success in surviving harsh conditions.
