- For the history of evolutionary biology, see History of evolutionary thought.
This timeline of the evolution of life outlines the major events in the development of life on the planet Earth. For context, see geologic time scale, and the history of Earth. Dates given are estimates based on scientific evidence. The table uses the symbols "Ma" for "mega-annum (million years ago)" and "ka" for "kilo-annum (thousand years ago)". English literature also uses the abbreviations "mya" (m.y.a) and "tya" (t.y.a) or "kya" in the same sense.
In biology, evolution is the process by which populations of organisms acquire and pass on novel traits from generation to generation. Its occurrence over large stretches of time explains the origin of new species and ultimately the vast diversity of the biological world. Contemporary species are related to each other through common descent, products of evolution and speciation over billions of years.

They are only children. They love fireworks and firecrackers. They are writing their history of life to cherish. Just like we were.
