2) A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Evolution is an important mechanism in the formation of new species. The evolution of a new species requires several components including all, BUT   A) Evolution of a new species requires a long time.     B) Evolution of a new species requires the need for a genetic change.     C) Evolution of a new species requires a separation that prevents interbreeding.     D) Evolution of a new species requires mutations that produce new genetic traits.

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.
