The rats, mammals Remarkably, they are masters of adaptation and capable of surviving in environments that challenge human resistance.
These small rodents demonstrate an incredible ability to adapt to extreme conditions, such as altitudes above 6,000 meters, in which humans would be unlikely to survive.
Adaptable mammals
A notable example of this feat is observed in the Llullaillaco volcano, located on the border between Chile and Argentina. Recent research has revealed that the oxygen concentration in these locations is only about 40% compared to sea level, making human life impossible without breathing support equipment.
The incapacity of beings humans of surviving in extreme altitude conditions, such as those found above 6,000 meters, is mainly linked to the decrease in atmospheric pressure and oxygen concentration in these environments.
At high altitudes, atmospheric pressure is significantly lower, which makes oxygen uptake into the lungs less efficient. This results in hypoxia, that is, a lack of oxygen in the body, which can lead to serious symptoms such as shortness of breath, dizziness, mental confusion and, ultimately, respiratory failure.
Furthermore, extreme temperatures, exposure to more intense ultraviolet radiation and scarcity of food and water at high altitudes also contribute to the difficulty of survival for humans in these challenging environments.
Rats are indeed peculiar beings
However, rats have been found to thrive in these challenging environments. This is truly surprising and highlights the remarkable adaptability of these small mammals.

One of the distinguishing characteristics of rats adapted to these altitudes is the structure of their ears. Due to the reduced atmospheric pressure at high altitudes, these mice have developed thinner and more delicate ears compared to their low-altitude counterparts.
This change is a necessary adaptation to optimize oxygen uptake in environments with lower atmospheric pressure.
Surprising adaptations have also been observed in lands that belonged to the Incas, where altitudes also reach impressive levels. You rats People who inhabit these regions demonstrate remarkable resilience and the ability to survive in conditions where most human beings would struggle to breathe and live.
The ability of rats to thrive in hostile environments, such as extreme altitudes, is a demonstration of the adaptation and survival potential of these small mammals.
In addition to their thin ears, they may also have developed more effective oxygen capture systems, as well as improved thermoregulation mechanisms to cope with the extreme temperature variations that occur in these regions.
Rats are true masters of survival in extreme conditions, challenging our preconceptions about the limits of life on the planet.
These discoveries provide a fascinating insight into the feats of evolution, the adaptability of mice, and highlight the importance of studying and understanding the diversity of life on Earth, not only to better understand biology, but to promote the conservation of its species and ecosystems in which they live.
