"Art is a trait so universal and ancient that it is almost surely innate"
The instinctive beauty gene, like the blackbird's orange-yellow beak, may have developed as a fitness signal. Making pictures is a non heritable brain disorder of unknown etiology, because aesthetics is part of our biology as expressed through the filter of awkwardness and irony. The mythical art form rapidly evolves and mutates in unexpected ways.
Art and genetics are good mysteries. Visual art moves from an esoteric specialty to being part of genetics. The criteria for goodness and badness are inherently shifting and not innate.

Awkwardness works as fitness indicators.

The genetic artist is interested in the statistical and inferential challenges that arise in making sense of genomic data.
Aliens believe that some artists send mixed signals. Canvas with brightly coloured topsides attract mates, for example, whereas camouflaged undersides protect against art predators.
