Timeline Of Evolutionary History Of Life
This timeline of evolution of life outlines the major events in the development of life on planet Earth since it originated until the present day. In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization, from kingdoms to species, and individual organisms and molecules such as DNA and proteins. The similarities between all present day organisms indicate the presence of a common ancestor from which all known species, living and extinct, have diverged through the process of evolution.
The dates given in this article are estimates based on scientific evidence.

“The point is, ladies and gentlemen, that greed, for lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through, and captures the essence of the evolutionary spirit.”

“The history of the genesis or the old mythology repeats itself in the experience of every child. He too is a demon or god thrown into a particular chaos, where he strives ever to lead things from disorder into order.”
—Ralph Waldo Emerson (1803–1882)
“A broad margin of leisure is as beautiful in a man’s life as in a book. Haste makes waste, no less in life than in housekeeping. Keep the time, observe the hours of the universe, not of the cars. What are threescore years and ten hurriedly and coarsely lived to moments of divine leisure in which your life is coincident with the life of the universe?”
—Henry David Thoreau (1817–1862)
