Physiological Adaptations

Physiological adaptations are changes in an organism's body that improve its ability to survive in a specific environment. For example, people living in high altitudes develop more red blood cells to carry oxygen efficiently, while animals in cold climates may grow thicker fur to retain heat. These adaptations occur over time through evolutionary processes, enabling species to thrive despite challenges like temperature, food availability, or altitude. Essentially, they are the result of natural selection, where the traits that help an organism succeed are passed down to future generations.
