What is any inherited characteristic or trait that increases chance for survival?

An inherited characteristic or trait that increases the chance for survival is known as an adaptation. These traits can enhance an organism's ability to find food, evade predators, or withstand environmental pressures. For example, the thick fur of arctic animals helps them retain heat in cold climates, improving their chances of survival. Adaptations are the result of evolutionary processes, allowing species to thrive in their specific habitats.
