title: Art and brain: the relationship of biology and evolution to art.
abstract: Visual art, as with all other arts, is spontaneously created only by humans and is ubiquitously present to various extents in all societies today. Exploring the deep roots of art from cognitive, neurological, genetic, evolutionary, archaeological, and biological perspectives is essential for the full understanding of why we have art, and what art is about. The cognitive basis of art is symbolic, abstract, and referential thinking. However, archaeological markers of symbolic activity by early humans are not associated with art production. There is an enormously large time gap between the activity and the appearance of sporadic art by early Homo sapiens, and another large time delay before appearance of enduring practice of art. The aesthetic aspect of art is not considered to be the initial impetus for creating it. Instead, archaeological markers suggest that the early beginnings of art are associated with development of stratified societies where external visual identifiers by way of body ornaments and decorations were used. The major contributing forces for the consistency in art-making are presumed to be the formation of socioculture, intragroup cooperation, increased group size, survival of skillful artisans, and favorable demographic conditions. The biological roots of art are hypothesized to parallel aspects of our ancestry, specifically animal courtship displays, where signals of health and genetic quality are exhibited for inspection by potential mates. Viewers assess displayed art for talent, skill, communicative, and aesthetic-related qualities. Interdisciplinary discussions of art reflect the current approach to full understanding of the nature of art.
