Oxford's renowned biologist Richard Dawkins puts the history of life on earth in perspective, using simply a piano. This short video is a great jumping off point for this brilliant lecture Dawkins gave back in 1991. It's called "Waking Up in the Universe, Growing Up in the Universe," and the 57-minute video pulls you deeper into some big questions. What’s the origin of life? Where do we fall in the scheme of life on planet Earth? What’s our role in the larger universe? And how lucky are we to have the brains and tools to understand the awesome wonders that surround us? Thanks to "Constantline" for sending today's video along.
