Cambrian Explosion

In evolutionary theory, the cambrian explosion is the extremely rapid development of new animal phyla (body shapes) that occurred at the beginning of the Cambrian Period approximately 530-550 million years ago.  The duration of time in which these new phyla occurred is approximately 10 million years.1
