Scientists have studied plant populations that have moved into areaswith low herbivory compared to the plant’s previous habitat. Aftermany generations in the new habitat, the plants produce fewerdefensive chemicals and grow larger than plants in the ancestralpopulation. How does natural selection explain these observations?(Hint: Producing defensive chemicals uses energy.)
