TALL

It may be because we’ve long had an innate sense of height as a proxy for health that most people find taller people attractive, and so afford them all the luxuries that attractive people receive. (“With this person, I can have offspring who will survive,” thinks our brain without telling us, only directing our sex organs to pulsate.) Sexual selection compounds the effects of natural selection that would favor larger stature —more advantageous for hunting and fighting, on the whole—making humans ever taller.
