Human beings communication relies on complex and multisensory systems. We use a wide range of cues to communicate, from facial expressions and different gestures, up to the most complex expressed in linguistic senses. Infants before acquire language, depend on gestures like pointing to make them understand. To point is a referential act, conceptually defined as the action that an individual realizes to give a direct indication to another one, concerning a specific object. It is a triadic transaction which involves an emitter, a recipient and an object, event or place of interest. This work focuses on pointing classification, its ontogeny, why and for what children points, which mechanisms are involved, and refers to the contribution of comparative psychology to the issue. The actual controversy between rich and lean interpretations of pointing gesture is discussed. Systematic studies on the origin and development of pointing, successful treatments of children with problems on earlier communication and non human primates raised in captivity using gestures support the associative and social learning based thesis.

Palabras clave : Communication; pointing; ontogeny; mechanisms; learning.
