MORE ON AMPHIBIOUS DEVELOPMENT
• These fishes- coelacanth had an advantage over other fishes as they had lungs and could breathe
on land. In time of shortage of water, these fishes came out of the pools which were drying out on
their muscular fins to search for other water. They might have added insects and other small
arthropods to their diet while moving and over time became less dependent on water.
• Earliest frogs, dating from the Jurassic Period, evolved south of the Equator
