When you learned about evolution, you probably were taught about random genetic variation in populations, inheritance of traits and about the role of natural selection in bringing about the “survival of the fittest.” This is often referred to as the Modern Synthesis of evolutionary theory. Some scientists think these principles are insufficient to explain the full breadth of evolution. They propose something called the Extended Evolutionary Synthesis which incorporates new finding in developmental biology, genomics, epigenetics, ecology, and the social sciences as important in explaining evolutionary outcomes. It does not negate variation, inheritance or natural selection, but adds new elements like animal behavior that paint a slightly different, and not-completely random, picture of how life evolves.
