Found this chart of the eras of the Earth while browsing a dictionary yesterday. In Buddhism, there is the term called kalpa to represent over 4 billion years, which happens to be about the age of the Earth. The scientific description of the origin of humans is quite fascinating! Because of the fairly recent mapping of the human genome, we are just beginning to see our evolution more clearly and our interrelatedness with all living beings.
Eras of Earth: One Kalpa for Human Evolution
Check out this great, yet old, video on evolution by Carl Sagan on the TV series Cosmos…
