Seed Magazine has a nice video showing The Evolution of Life in 60 Seconds.  It gives you a good feel for “deep time“: the immense span of ages that is the history of the Earth.  It is especially notable how brief the entire Phanerozoic (from the Greek for “visible life”), the last 550 million years or so of largish animals with hard parts, is.
