Step 1:: Identify the correct answer based on the concept of evolution by natural selection.
In the context of evolution, the correct answer should be the one that allows for the gradual development of webbed feet in ancestral ducks over generations. This implies that the majority of ducks in each generation have more webbing on their feet than their parents, as this trait offers a survival advantage in their environment.
Step 2:: Identify the answer choice that aligns with the concept of evolution by natural selection.
Answer choice b) most ducks had more webbing on their feet than their parents
Step 3:: Explain the reasoning behind the chosen answer.
The process of evolution by natural selection suggests that traits that offer a survival advantage become more common in a population over generations. In the case of ancestral ducks, increased webbing on their feet provides a selective advantage for swimming and finding food. Therefore, ducks with more webbing on their feet are more likely to survive and reproduce, passing this trait onto their offspring. Over time, this leads to an increase in the prevalence of webbed feet in the duck population, making answer choice b) the correct one.
Final Answer
Most ducks had more webbing on their feet than their parents (b)
