Evolution

An organisms with the “best” traits (adaptations) will live longer and

reproduce more than others, causing changes in the population over time by acting on traits that are heritable

• Evolution

• Natural Selection

• Fitness

• Variation

Answer explanation

Natural Selection is the correct choice because it describes how organisms with advantageous traits survive and reproduce, leading to changes in the population over time.

Genes that are beneficial to the species will....

• evolve a new species

• will not be passed down to its' offspring

• become more common over time

• cause the extinction of a species

Answer explanation

Genes that are beneficial to the species will become more common over time as they provide an advantage, increasing their frequency in the population.
