In a population of lizards, 25% of dark coloring and 75% have light coloring. Overtime, the environment where the lizards live becomes fostered. The dark lizards can hide more easily than the light lizards because they blend in with the tree trunks. The lizard population changes into 80% dark colored lizards and 20% light colored lizards. As an example of?

This is an example of natural selection and adaptation. The change in the lizard population's coloring distribution over time is a result of the environment favoring dark-colored lizards who can better camouflage with tree trunks. This phenomenon is known as natural selection, where certain traits are more advantageous for survival and reproduction in a specific environment, leading to the gradual evolution and adaptation of a population.
