[edit] Light Switch Theory
In his 2003 book In the Blink of an Eye ISBN 0-7382-0607-5, Parker proposes that the Cambrian Explosion, the sudden diversification in animal fossil forms at the start of the Cambrian Era, was due to the development of the vision faculty and the consequent intensification of predation.
