Give examples of the three types of natural selection.

Write an explanation for how the process of evolution primarily results from competition for limited resources (such as water, shelter and mates) and differences in the abilities of individuals in a population to survive and reproduce in that environment.

List and explain the three types of natural selection.

Consider this example. On a tropical island, there are iguanas that are green, blue, and yellow. The green iguanas can camouflage in the green grass, the yellow iguanas can camouflage in the dry, yellow grass. And the blue iguanas try to run fast to get away from prey. Over time, the blue iguanas disappear on the island, while the green and yellow iguanas survive. What type of natural selection is this?    A. Balancing or Stabilizing selection   B. Disruptive or Diversifying selection   C. Directional selection   D. Sexual selection
