Art and brain coevolution.

The competence for appreciating beauty appears to be a human universal trait. This fact points out to a phylogenetically derived capacity that, somehow, evolved by means of natural selection. To detail how this evolutionary process took place is difficult to determine, because appreciating beauty is an elusive capacity, impossible to be detected in the fossil record. However, efforts have been made to understand the main characteristics of such competence, particularly by means of the advances of neuroaesthetics. Here, we examine some of the results obtained in experimental research to identify neural correlations of the appreciation of beauty, as well as archaeological and paleoanthropological proofs of the relationship existing between production of artistic objects and evolution of the human brain.
