(a film review by Mark R. Leeper)

THE SERENGETI RULES looks at a new paradigm for seeing the interactions of species in nature. Previously it was thought that human influence had overpowers nature and too often was killing the order of nature. It is now thought that in some ways nature wins out. An action in the eco-system damage may damage the entire system and that change may stimulate a new predator may come to power. The eco-system may then reach a new stable environment. A simple collection of rules may govern population sizes. Some animals are very important to govern the eco-system while others may not be. The species on which the population sizes most depend are called keystone species. Importance to the ecosystem is not the same thing as physical strength. A simple herbivore may be controlling the system. The documentary is based on the work of Sean B Carroll. Rating: +2 (-4 to +4).
