Timeline Of Evolution

This timeline of evolution of life outlines the major events in the development of Life on the planet Earth . For context, see Biology , Evolution , the Geologic Time Scale , and the History Of Earth . Dates given are estimates based on scientific evidence. The table uses the abbreviations " MYA " for "million years ago" and " KYA " for "thousand years ago."

In Biology , evolution is the process by which populations of organisms acquire and pass on novel Trait s from generation to generation. Its action over large stretches of time explains the origin of New Species and ultimately the vast diversity of the biological world.
