Assume you are studying a population of hummingbirds. You discover that the smallest hummingbirds can't keep their eggs warm and those eggs tend to fail. You also discover the largest hummingbirds tend to accidentally crush their eggs, so those eggs fail. The medium-size hummingbirds therefore have the highest fitness. What type of selection would this result in? a. Directional selection b. Sexual selection c. Disruptive selection d. Stabilizing selection
