Behavioral modernity is a term used in anthropology, archeology and sociology to refer to a set of traits that distinguish present day humans and their recent ancestors from both living primates and other extinct hominid lineages. It is the point at which Homo sapiens began to demonstrate a reliance on symbolic thought and to express cultural creativity. These developments are often thought to be associated with the origin of language.[1] There are two main theories regarding when modern human behavior emerged.[2] One theory holds that behavioral modernity occurred as a sudden event some 50 kya (50,000 years ago), possibly as a result of a major genetic mutation or as a result of a biological reorganization of the brain that led to the emergence of modern human natural languages.[3] Proponents of this theory refer to this event as the Great Leap Forward[4] or the Upper Paleolithic Revolution. The second theory holds that there was never any single technological or cognitive revolution. Proponents of this view argue that modern human behavior is basically the result of the gradual accumulation of knowledge, skills and culture occurring over hundreds of thousands of years of human evolution.[5] Proponents of this view include Stephen Oppenheimer in his book Out of Eden, and John Skoyles and Dorion Sagan in their book Up from Dragons: The evolution of human intelligence. Modern human behavior is observed in cultural universals which are the key elements shared by all groups of people throughout the history of humanity. Examples of elements that may be considered cultural universals are language, religion, art, music, myth, cooking, games, and jokes. While some of these traits distinguish Homo sapiens from other species in their degree of articulation in language based culture, they all have analogues in animal ethology. Since cultural universals are found in all cultures including some of the most isolated indigenous groups, scientists believe that these traits must have evolved or have been invented in Africa prior to the exodus.[6][7][8][9] Classic evidence of behavioral modernity includes: finely-made tools fishing evidence of long-distance exchange or barter among groups systematic use of pigment (such as ochre) and jewellery for decoration or self-ornamentation figurative art (cave paintings, petroglyphs, figurines) game playing and music burial A more terse definition of the evidence is the behavioral B's: blades, beads, burials, bone toolmaking, and beauty.[10] It might be thought that behavioral modernity preceded language, but the complex behaviors from the list above are thought to suggest language was necessary and that they must have been at least contemporary developments.
