Problem: A researcher notices that in a certain moth species, some females prefer to feed and lay eggs on domesticated solanaceous plants like potatoes and tomatoes. Other females prefer to feed and lay eggs on the wild solanaceous plants like Datura that sometimes grow in and near the agricultural fields. Both male and female moths primarily use scent to find these plants from afar. Females tend to mate where they feed, and the researcher finds a genetic basis for scent preference in these moths. A) Would you expect speciation to happen? Why or why not? B) Explain and discuss isolating mechanisms, selection and type of speciation.
