21.20. Which of the following statements about evolution and ecology is TRUE? Evolutionary processes and ecological processes cannot occur on similar time scales. Evolution by natural selection is generally not mediated by ecological phenomena (such as predation). The evolution of a population will not affect how its members interact with individuals of other species. Rapid evolution is possible when environmental or ecological conditions change quickly. .
