The first life forms on the planet were microscopic single-celled organisms it took billions of years before more complex creatures evolved first jellylike bodies and then armored shells on their outsides and finally the first backbone and the beginnings of fish.

Life evolved in the sea in a water-bound planet but landmasses slowly appeared and aquatic life began to explore different ways to colonize it. Plants were the first pioneers then insects to feast on them and then each other.
