The organisms which invaded the land first are supposed to be plants. About 470 million years ago, during the Ordovician epoch of the Paleozoic era, the first terrestrial plants emerged. Life quickly began to diversify throughout this time. The plants were designed to resemble mosses and liverworts, which are primitive thalloid.

  • There is no water vascular system in these plants.
  • The Silurian epoch saw the emergence of the first vascular plants.
  • After plants, animals, bacteria, and viruses live on the land.
