Q7.In the Mountains and Valleys exercise, which of the following parameters had the largest influence on whether the finch population evolved a bimodal distribution? A. The speed at which the model ran. b.The difference in carrying capacity between the wet versus dry sides of the island. C. The number of chicks each pair of parents produced each year. D. How far the birds flew when looking for a mate.

Q8. The final exercise, Large and Small Seeds, showed that: A. In the absence of geographic barriers, a population cannot evolve distinctive subpopulations. B. Bimodal distributions are more likely to evolve when geographic barriers are absent. C. Bimodal distributions only evolve when the population\'s food supply is divided into two types. D. Bimodal distributions can evolve when geographic barriers are absent.

Solution
