A nice video to watch.

The Evolution of Life in 60 Seconds is an experiment in scale: By condensing 4.6 billion years of history into a minute, the video is a self-contained timepiece. Like a specialized clock, it gives one a sense of perspective. Everything  from the formation of the Earth, to the Cambrian Explosion, to the evolution of mice and squirrels  is proportionate to everything else, displaying humankind as a blip, almost indiscernible in the layered course of history.
