Consider that human evolution unfolds in a fashion not dissimilar to the way an accordion player produces melody and harmony while inflating and deflating his instrument over time. The accordion player may observe his audience and modify cadence or change the tune depending on whether folks are dancing, how fast they’re dancing or whether they are paying attention at all. The instrumentalist’s environment informs the tune he plays and how he plays it.
Human communities are composed of many types of folks. Not just the individuals in communities are molded by evolutionary processes, but the communities themselves behave like selected targets with those communities that exhibit a variety of useful features that encourage a thriving population surviving and procreating. This has been called a balanced polymorphism. A wide variety of human types can contribute to a healthy, balanced polymorphism and a healthy community.
For example, in contemporary society, we observe the artists, caregivers and athletes performing and serving while exhibiting strengths peculiar to their particular neurology, psychology and physical proclivities. Politicians and business people do what they do best, stoking the economy and growing opportunities. Aesthetics and usefulness combine to create a satisfying social experience and a balanced society.
