History Of Life On Earth

Life evolved in the sea on 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.

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

It took a long time for vertebrates to really take over the land, but once they did, there was no turning back. Reptiles seemed to win the race, some becoming the biggest creatures to ever walk the Earth.

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.
