Different finch species live on different islands. Why are humans so genetically similar? (b) How does competition among humans differ from the competition in other animal species? Thats because females of all the capuchino species look identicalits often impossible to tell them apart, even in the hand. Unlike Darwins finches, in which environmental conditions such as food supply rewarded birds with different beak shapes, the capuchino finches all eat the same type of food and live in grasslands scattered across South America. B) not all mutations are beneficial. If so, how do modern humans differ from them? How do modern biology, evolution, and natural selection explain why there are differences in innate aptitude in animals (such as there are humans who are smarter than others, some are more artistic than others, etc.)? d. Fertile offspring are produced. Another theory is that individuals of a species could look different today if they had different genetic mutations. c) Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. Yes, all individuals can change a little and pass those changes on to their offspring. As in all species, there is variation among individual human beings, from size and shape to skin tone and eye color. Genetic drift is evolutionary change resulting from: a. chance differences in reproductive success b. natural selection c. differences in individuals' fit to their environment d. mutation. Explain. No, species do not change even after many generations, so individuals of the same species would not look different. Why are humans so different from other animals?

Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. a. A. They were therefore able to eat aquatic plants and get enough food to survive and reproduce.Ducks with more webbing were better at eating aquatic plants than ducks with less webbing, so the ducks with more webbing survived and reproduced better than ducks with less webbing.Ducks with less webbing needed to grow more webbing in their feet in order to improve their access to aquatic plants, which allowed them to survive better and reproduce more.Q6.10.
