- 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.arrow_forward2) A species is a group of individual organisms that interbreed and produce fertile, viable offspring.
