Cultural universal

A cultural universal (also called an anthropological universal or human universal), as discussed by Emile Durkheim, George Murdock, Claude Lévi-Strauss, Donald Brown and others, is an element, pattern, trait, or institution that is common to all human cultures worldwide. Taken together, the whole body of cultural universals is known as the human condition. Evolutionary psychologists hold that behaviors or traits that occur universally in all cultures are good candidates for evolutionary adaptations. Some anthropological and sociological theorists that take a cultural relativist perspective may deny the existence of cultural universals: the extent to which these universals are "cultural" in the narrow sense, or in fact biologically inherited behavior is an issue of "nature versus nurture".

In his book Human Universals (1991), Donald Brown defines human universals as comprising "those features of culture, society, language, behavior, and psyche for which there are no known exception", providing a list of hundreds of items he suggests as universal.

The emergence of these universals dates to the Upper Paleolithic, with the first evidence of full behavioral modernity.

Among the cultural universals listed by Brown (1991) are:

The observation of the same or similar behavior in different cultures does not prove that they are the results of a common underlying psychological mechanism. One possibility is that they may have been invented independently due to a common practical problem.

Since any culture that have been studied by anthropologists have had contact with at least the anthropologists that studied it, and anthropological research ethics slows the studies down so that other groups unbound by such ethics, often at least locally represented by people of the same skin color as the supposedly isolated tribe but significantly culturally globalized, reach the tribe before the anthropologists do, no truly uncontacted culture has ever been scientifically studied. This allows outside influence to be an explanation for cultural universals as well. This does not preclude multiple independent inventions of civilization and is therefore not the same thing as hyperdiffusionism, it merely means that cultural universals are not proof of innateness.
