The main characteristic of human behavior is the symbolism. But symbolism remains still unknown in different aspects. In this paper we conduct an structural analysis of human symbolism, through a methological synthesis of diverse sciences that study the human being (Evolutive Biology, Neurology, Psychology and Sociology). As a result, an innovative Psychobiological explanation about the human behavior and its phases has showed up. This method develops a new explaining way about the origin and evolution of our symbolical and complex behavior. As a result, an innovative Psychobiological explanation about the human behavior and its phases has showed up from the origin to current manifestations, in order to design a imitable study method. Subsequently we have to applied this method in known funerary behavior of the Middle Paleolithic of Europe, Near East and MSA of South Africa, to evaluate intention and symbolism associated. Also, consider cannibalism as a form of disposal of dead in this period, trying to understand if undertaken as survival or behavior associated with symbolic elements similar to those associated with burials.

: El simbolismo es la principal caracter?stica de la conducta humana, pero sigue siendo desconocido en muchos aspectos. En el presente trabajo se realizar? un an?lisis estructural del simbolismo humano, por medio de una s?ntesis metodol?gica elaborada con las aportaciones de varias ciencias relacionadas con los seres humanos (Biolog?a evolutiva, Neurolog?a, Psicolog?a y Sociolog?a). Tal s?ntesis ha dado lugar a un modelo Psicobiol?gico sobre el comportamiento humano, que nos permite elaborar un m?todo adecuado para el estudio del simbolismo, desde su origen hasta su plena manifestaci?n con las caracter?sticas actuales. Posteriormente, se aplicar?a a las conductas funerarias que se conocen del Paleol?tico Medio de Europa, del Pr?ximo Oriente y del MSA de Sud?frica, para valorar la intencionalidad de los enterramientos, junto con el posible simbolismo asociado a ellos. Tambi?n, se estudiar? la antropofagia como forma de eliminaci?n de los cad?veres en este periodo, intentando comprender si se realizaba como conducta de supervivencia o asociada a elementos simb?licos similares a los relacionados con los enterramientos.
