" Yet biologists feel that animals are no strangers to aesthetic expression. The New Guinean bowerbird's nest decorations are as good an example as any. The thatched nests can be so large and well-constructed that they once were mistaken for the huts of timid people, who never showed up. The nests often have a doorway with carefully arranged colorful objects, such as berries, flowers, or iridescent beetle wings. The male who built the bower keeps flying in new ornaments, shifting everything around with a critical eye, fussing over the arrangement, moving back to look at the whole from a distant anglelike a human painter with his painting-and then continuing the rearrangement. He is very sensitive to the fading of his flowers, replacing them with fresh ones as soon as necessary. Young males build crude "practice" bowers, tearing them down, then starting over again, until the construction holds up as it should. They also frequently visit the completed bowers of adult males in the neighborhood and see how the ornaments are laid out. There are ample learning opportunities here, and it has been noted that bower decorations differ in color and arrangement from region to region, which suggests culturally transmitted styles.
Is this art? One could counter that it isn't: howerbird males are genetically programmed to engage in this activity just to attract females. Yet, while it is true that females select mates on nest quality and their equivalent of a stamp collection, the argument is not nearly as good as it sounds. To contrast these birds with our species requires that one demonstrates that human art does not rest on an inborn aesthetic sense and is produced purely for its own sake, not to impress anyone else. Both are unlikely. In fact, Geoffrey Miller argues in a recent book that impressing others, especially members of the opposite sex, may be the whole point of human art!
What if our artistic impulse is ancient, antedating modern humanity, and perhaps even our species? What if it rests on a delight in self-created visual effects and a penchant for certain color combinations, shapes, and visual equilibriums that we share with other animals? Would admission in any of these areas diminish the significance of and pleasure derived from human art? Isn't it possible that our basic distinctions in art, our musical scales, and our preference for symmetrical compositions, go deeper than culture, and relate to basic features of our perceptual systems?
