Detailed explanation-1: -We most typically think of natural selection working at the level of the individual, favoring those better at leaving behind more individual descendants. However, with a little imagination, we can see how natural selection might work at other levels of biological organization as well.

Detailed explanation-2: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Detailed explanation-3: -Individual organisms don’t evolve. Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions.
