There's a very persuasive argument that humans exhibit aposematism; in particular, that we evolved a very strong scent as a warning to potential predators. Objectively speaking, most humans have extremely strong scents relative to other animals (especially non-aposematic animals), regardless of whether we personally find it strong or offensive. This is somewhat blunted for populations at cold, northern latitudes (e.g. East Asians) that evolved fewer sweat glands, so notwithstanding our origins there are now clearly significant phenotypic variations.

A slightly more radical theory is that we also evolved the ability to dance and chant in unison for similar reasons--to intimate predators. That we evolved to wear clothing (in particular, colorful costumes and displays) would presumably be related, if true.
