Darwinism, the biosphere constantly changes. Culture changes as well. In the biosphere as well as in the cultural realm, new characteristics arise over and over again and some novelties persist and lead to lasting changes. The types of entities that are involved in these changes are genes and organisms in the case of biological evolution, and cultural units such as ideas, values, beliefs, patterns of behavior, and artifacts in the case of culture. Today, biological evolution is believed to be explainable by Darwinian evolutionary theory. Cultural change, however, is thought to arise through creative acts and selective choices of individuals, leading to the diffusion of novelties. Culture is usually defined as consisting of those characteristics of individuals that are not innate but created or learned by individuals during their life. Creativity in its basic sense is the human capacity to create new and valuable responses
