Look at the human: a comparatively dull-looking, weak being. No colour, no tusks, no nothing. But look again, and you will see the tanks, works of art, fashion, music, superior communication, and the artificial environments. Nature might have taken a gamble when physical strength was selected second to a growing brain and intelligence. The gamble certainly paid off, humans don't need strength, we have guns and walls, humans don't need colours, we have dyes and clothes (that inadvertently rhymes!). So we experience, and have experienced, much fewer natural selection pressures and responses, and more artificial responses. For example, although the natural selection pressure of cold weather resulted in a thick fur in polar bears, and therefore turned into a sexual selection pressure due to furry polar bears surviving for longer, the same natural selection pressure resulted in a completely different adaptation for Eskimos - building igloos and shooting bears. In fact, human int...
