1) In a population of lizards, 25 percent have dark coloring and 75 percent have light coloring. Over time, the environment where the lizards live becomes forested. 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 percent dark-colored lizards and 20 percent light-colored lizards.What is this an example of?
This is an example of natural selection. The change in the lizard population's coloring over time is a result of the environmental pressures favoring the survival and reproduction of dark-colored lizards, leading to an increase in their proportion in the population. This is a classic example of how natural selection can drive evolutionary changes in populations.
