This is a TED talk with Dr. Denis Dutton discussing how we evolved our sense of beauty. What I’ve always found fascinating about sexual selection is that it can lead to selection pressures toward higher intelligence, increased motor skills, and other more highly developed sensory organs. In humans, it likely gave us wit, humor, our enjoyment of music, and our aesthetic appreciation of art. As Dr. Dutton points out, all human arts require precise skill. Take playing the piano for instance. Sexual selection attracts women to men with brains which can process complicated sound patterns, control highly coordinated motor movements, and compose the complicated music in the imagination. Women aren’t as attracted to men who can’t do this, so an exponential increase in human brain power results over subsequent generations. This is why women are into musicians and other artistic types.
