“When we ponder the workings of the human body or of the life of the Serengeti National Park, the details would seem overwhelming, the parts too numerous, and their interactions too complex. The power of a small number of rules…is their ability to reduce complex phenomena to a simpler logic of life.” (10) With this thought, Sean B. Carroll introduces his book, The Serengeti Rules:  The Quest to Discover How Life Works and Why It Matters.
