This thread is to honor the 200th birthday of the great Charles Darwin coming up this February. Anyway, back to the topic at-hand. I hypothesize that the reason why female humans wear high-heeled shoes ("pumps") is to gain a deceptive advantage in their physical height. This will make them more appealing to the taller males of our species; thus, if the female can sucessfully have offspring with the taller male by deceiving him thus, her offspring may have a higher chance of reproductive sucess. This fits well within the framework of the progress of human evolution, and that framework is that the human species is evolving into a taller species, not a more intelligent one (this framework fails on small landmasses, where the 'island dwarfing' phonomena takes place). If you're a male and you see a female wearing pumps, it would serve you best if you try to visually remove about three inches off the female's apparent height before engaging in conversation.
