And an aquatic bird population sunbirds had long legs other birds have short legs. The food supply is minimal. The birds with long legs are able to weigh farther into the water where they can find fish overtime. The birds with long legs become more common what scientific term best describes that this scenario would it be mutation natural selection, fitness or selective pressures?
The scientific term that best describes the scenario is natural selection. Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, thereby increasing their frequency in a population over time. In this scenario, the birds with long legs have an advantage in finding fish in the minimal food supply, allowing them to survive and reproduce more successfully than birds with short legs. Consequently, the population of birds with long legs becomes more common over time due to natural selection.
