  Probably through better nutrition and living conditions for children. That’s why this change has happened really recently (just over the last 100 years), whereas if this was evolution, it would have taken thousands of years.

  Do you mean – why do men tend to be bigger than women? Looking across lots of different species, it seems that the males are bigger than females in species where the males compete for females (and the females don’t get much choice in the matter). In these species, the biggest strongest male gets all the females. In other species, males & females are the same size and there is more monogamy and more female choice. Humans are half way in between, suggesting that in our evolution we were partly but not entirely monogamous.
