The book also discusses how the three most discussed hypothetical functions of the human arts––competition for attention and (loving) acceptance, social cooperation, and self-enhancement––are not mutually exclusive, but can well be conceived of as different aspects of the same processes of producing and responding to the arts.

Finally, reviewing the current state of archeological findings, the book advocates a new hypothesis on the multiple origins of the human arts, posing that they arose as new variants of human behavior, when three ancient and largely independent adaptions––sensory and sexual selection-driven biases regarding visual and auditory beauty, play behavior, and technology––joined forces with, and were transformed by, the human capacities for symbolic cognition and language.
