4.Genetic Mutation

Answer 2

Reproduction

In order for natural selection to act on a given population, that population must reproduce to create a new generation. Over many generations, individuals with traits most suitable for their environment tend to reproduce more than those that don't. As such, natural selection works to maximize the number of individuals with those favored traits while those with less advantageous traits slowly die off.

Heredity

Heredity works hand-in-hand with reproduction since the genes of the parents combine to create the genes of their offspring. Parents with advantageous traits must pass those traits on to their offspring in order for natural selection to act. Otherwise, the genes which create the advantageous traits would die with the parents without being copied to the next generation. Speciation occurs when members of a species are geographically isolated into differing environments, allowing for unrelated lines of heredity.

Variation in Characteristics

Natural selection can only occur within a population when members of the population have a variation in individual traits. For example, a study of natural selection on color within a population requires different individuals to have varying colors. Without a variation in characteristics, there are no traits for nature to "select" over others.
