What are some of the ideas about the cause of the Cambrian Explosion?
The Cambrian Explosion may have occurred due to a genetic revolution.
Furthermore, a rise in the oxygen levels may have allowed animals to become
larger. An additional explanation was that there was an "arms race" to evolve into
an organism that would not be eaten.

Can someone help me put this in my own words (this came from the answer key) or go to the website where my teacher is wanting us to get the answer from and give me the answer please, will mark brainliest to the best answer!
