By the year 2000, the graph shows the population of light colored moths significantly increasing. Explanation: Species evolve over time scales/generations, and individuals that possess traits that are advantageous in the current environment can live at a higher frequency and transfer those advantageous traits on to their offspring. Most ducks had less webbing on their feet than their parents. Does the mechanism produce a change in individuals or populations? Explain why only populations evolve but individuals do not. C.
