The larvae of some insects are merely small versions of the adult, whereas the larvae of other insects look completely different from adults, eat different foods, and may live in different habitats. Which of the following most directly favors the evolution of the latter, more radical, kind of metamorphosis?
A)natural selection of sexually immature forms of insects
B)changes in the homeobox genes governing early development
C)the evolution of meiosis
D)B and C only
E)A, B, and C

Changes in the homeobox genes governing early development can lead to the evolution of more radical metamorphosis, as these genes control the development of body structures and organs. Mutations in these genes can result in changes in body form and structure, leading to the evolution of more different-looking larvae and adults. The evolution of meiosis and natural selection of sexually immature forms of insects are not directly related to the evolution of radical metamorphosis.
