Explain how constancy of species may be maintained through natural selection

Species in a population show variation in characteristic. These act as the basis for genes of the next generation.

Individuals with characteristic favored by the environment survive to pass on their genes to the next generation.

Those with unfavorable characteristics are weeded out.

This naturally controls the population size as selection pressures are constantly changing as do the adaptations of organisms from time to time.
