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.

The dinosaurs had a long and glorious reign, but it was not to last, and with their passing, a land of opportunity was laid bare for the little mammals that had scampered about their feet.
