The development of life over the last 3,700 million years of the Earth's history is one of the great stories told by modern science. During most of this time living things left only traces to indicate their existence. Then, about 544 million years ago, during what is referred to as the Cambrian explosion, animals learned how to make hard, mineralized body parts. Suddenly rocks resulting from sand and mud deposits become laden with fossil remains, and our picture of ancient life grows enormously in scope and detail.
"Oh me! Oh life! you are here...the powerful play goes on, and you may contribute a verse."
Walt Whitman

"And Time, a maniac scattering dust,
And Life, a Fury slinging flame."
Lord Tennyson
