QuestionAnatomy and Physiology

The process of evolution typically involves small, gradual changes in successive generations. In the case of webbed feet in ducks, it is reasonable to assume that the amount of webbing on their feet would change incrementally rather than drastically.

Option A: "Most ducks had about the same amount of webbing on their feet as their parents." This option suggests no change or little variation in webbing amount, which is not consistent with the concept of evolution involving gradual changes. Option B: "Most ducks had more webbing on their feet than their parents." This option is consistent with the principle of evolution, as it implies a gradual increase in the amount of webbing over generations. Option C: "Most ducks had less webbing on their feet than their parents." This option contradicts the idea of evolution leading to increased specialization or adaptation, as it suggests a reduction in the amount of webbing. Option D: "The amount of webbing on ducks' feet had no relationship with the amount their parents had." This option is also not consistent with the principle of evolution, which relies on the inheritance and modification of traits across generations.
