Alternative hypotheses concerning the origin of metamorphosis are contrasted. A model is proposed which postulates that insect metamorphosis is an effect of adaptations to differing sets of environmental selective pressures during ancestral amphibiotic life. It is postulated that amphibiotic life led directly to the selection of phase specific genes which control metamorphosis.
