4). a particular bird species found in north america obtains most of its food energy by catching and eating insects. a mutation arises in this bird population that increases the length of its beak. although many mutations are harmful, this particular mutation has increased the ability of the bird to catch and eat certain insects. which of these is the most likely outcome of this mutation? a) the insects that are eaten by this bird are likely to become extinct. b) sharp pointed beaks will result in the birds eating other more unusual food items. c) other bird species will be more likely to also develop pointed beaks in order to compete. d) individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation. 5). in 1831, charles darwin visited the galapagos islands. while observing the giant land tortoises that lived on these islands, darwin noted that the shape of the tortoise shell varied depending on which island the tortoise lived. tortoises on one island had round shells, for example, whereas tortoises on a neighboring island had more flattened, saddle-shaped shells. which statement best summarizes darwin's explanation for these differences? a) random mutations caused the shape of the shells to fluctuate periodically. b) the shape of the tortoise shell varied because the predators on the islands were all similar. c) the particular shape of the shell was best suited for the island on which the tortoise was living. d) tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter.
