Found this on another blog: How Stuf Works. Found it very interesting so had to share it with you, enjoy.
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.
This puts our troubles, goals and deeds in perspective.
