Andrew Parker is a Professor at the Natural History Museum in London. In his 2003 book In the Blink of an Eye, Parker proposes that the Cambrian Explosion, the sudden diversification in animal fossil forms at the start of the Cambrian Period, was due to the development of the vision faculty and the consequent intensification of predation. His 2006 book, Seven Deadly Colours, describes the variety of methods of producing colour that have evolved in nature, and their implications for animal lifestyles. Parker is also an agnostic. His 2009 book The Genesis Enigma argues that the Book of Genesis is surprisingly accurate and in accord with science. This caused him to conclude that the author of Genesis might have been inspired by God, although his work since demonstrates a neutral stance on religion.
