Most of us have spent some time thinking about the origin of life as we've come to know it, the beauty of the forest, and the mysteries of the ocean.  For some, a higher power explains it all - for others, evolution holds the key that unlocks the door.  Kenneth Miller shares his passionate beliefs about how life unfolds. Miller is professor of biology at Brown University.

Millers diverse publications defend the scientific integrity of evolution, addressing challenges such as "intelligent design". His book, "Finding Darwin's God: A Scientist's Search for Common Ground between God and Evolution", examines the scientific status of evolutionary theory and its relationship to religious views of nature.
