Which of the following BEST describes the theory of natural selection? Living organisms change over time.   Each species produces many more offspring than can survive long enough to reproduce. The offspring that do survive contain genes that are inherited from the parents.   There is variation among the members of a species. Some of this variation is genetically determined and so can be passed on to future generations.   Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.   There is a struggle for existence among the members of a population.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
