many plants benefit from interaction with mutualistic herbivores such as pollinators or seed dispersers and have evolved defense that only target harmful herbivores for example, chili seeds pass safely through the digestive system of birds and are dispersed in the droppings but are destroyed when eaten by mammals. not surprisingly, capsaicin the compund that gives chilies their hot flavor, affects mammals but not birds, so mammals do not eat spicy food while birds will. explain the selective process that may have led to plants evolving this specific defense. be sure to include the different components of natural selection in your explanation
