If there is NO Do any of our fossil relatives or other species share some aspects of this unique set of characteristics? If a species is evolving, when is it considered a new species different from the organism it evolved from? d) No, species do not change even after many generations, so individuals of the same species would not look different. Scientists look for those rare instances when a species suddenly diverges, or radiates into multiple forms, each with a different appearance or behavior. His observations of the embryos lead him to conclude that the species share a common ancestry. Of course, the source of that female preference probably resides somewhere in the DNA, too. Answered: Q6.5.
