Earth’s vegetation history

Earth's vegetation history

As plants evolved on Earth, the vegetation signal that reveals their presence became stronger.

430 million years ago: Silurian Period. A mass extinction took place, wiping out nearly half of marine invertebrate species. The first land plants emerge, starting at the edge of the ocean. Plants evolve vascularity, the ability to transport water and nutrients through their tissues. Ocean life becomes larger and more complex, and some creatures venture out of reefs and onto land.

300 million years ago: Late Carboniferous. Plants developed root systems that allowed them to grow larger and move inland. Environments evolved below tree canopies. Atmospheric oxygen increased as plants spread on land. Early reptiles have evolved, and giant insects diversify.
