When I talk about sexual selection I usually make sure to have an accompanying visual of a peacock to go with the post. But really I could have used a dandy as an illustration, or perhaps in our day & age "The Situation". Unlike the peacock much of what passes for human "plumage" is not a result of native biological processes, but rather refashioning the materials of other organisms or synthetics into a sort of second skin (or skins with all our layers). In other words, clothes. These artificialities are so essential to our own identity as individuals that they often mark out our tribal affiliations, in pre-modern and post-modern contexts. Whole industries exist to cater to both our utilitarian needs and aesthetic sensibilities in regards to how we dress ourselves. The definition of a cyborg usually connotes a synthesis of biological with electronic. Perhaps that is because our artificial extensions in the form of clothes have seamlessly merged with our self-images, to the point where it would be ludicrous to perceive ourselves as merged entities. If you encountered many of your acquaintances or friends naked not only would embarrassment ensue, but I suspect one might initially not recognize them. A naked physique without distinctive aspects of clothing one associates with someone strips away individual identity.
