Collective unconscious (kollektives Unbewusstes) refers to the unconscious mind and shared mental concepts. It is generally associated with idealism and was coined by Carl Jung. According to Jung, the human collective unconscious is populated by instincts, as well as by archetypes: ancient primal symbols such as The Great Mother, the Wise Old Man, the Shadow, the Tower, Water, and the Tree of Life. Jung considered the collective unconscious to underpin and surround the unconscious mind, distinguishing it from the personal unconscious of Freudian psychoanalysis.
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". Cultural evolution is the change of this information over time. Cultural evolution, historically also known as sociocultural evolution, was originally developed in the 19th century by anthropologists stemming from Charles Darwin's research on evolution.
