Artistic expressions convey ideas, emotions, and norms, and reflect talent, skill, and capability to which the audience resonates. Both artist and viewer participate in art’s communication whose underlying cognitive bases are symbolic and abstract, not unlike language’s underpinnings in this regard. Exploring the distant evolutionary times of our genus, Homo sapiens, provides clues into why and how the arts emerged. I argue that originally they held utilitarian value for survival of small social groups, communicating messages of symbolic identity and cohesion. The communicative nature of art, and its acceptance into cultural practices, explains why it is when language abilities degrade following brain injury in nonartists, some resort to expressing themselves through paintings and drawings. These formats have been socially accepted forms of expression in the cultures in which these nonartists lived; they did not invent or create alternative cultural expressions. Similarly, established professional artists with brain injury, regardless of etiology or hemispheric laterality of injury, continue to produce their art without obvious or serious alterations to their talent, skills, or creativity. Such outcomes support observations that art’s communication system lacks localized, specialized brain regions, unlike language in this regard, and renders it a flexible system of communicating experiences, thoughts, emotions, imagination, and talents, skills, and creativity.
