The average man is larger than the average woman, because in the past males competed among each others over females. The same thing in animals, gave little variations in size, comparing to humans. However, humans not only differ widely in size among ethnic groups, but also within the group itself. The dominant assumption among people of different cultural backgrounds (This is my observation, so far), that a man marries a woman which is shorter than he is, and therefore distribution of human height should have been around an optimal value, which gives the best chances of surviving the local environment and successfully competing with other males. Even observing isolated populations in documentary films seems to show a relatively wide range of sizes. I don't know, however, how that distribution was in ancient populations (Measuring skeletons or plaster casts of the victims in Pompei in Ancient Rome). Did body size become less important in everyday's life even early in human history? If so, why do we still take it into account, when chosing a mate and in many other activities as well?
