But this difference in height/size is also dependent on nutrition
levels. Many people in developing countries are smaller because of poor
diets. In many cases, descendents of immigrants from these countries to
industrial countries end up being much bigger than their parents and/or
grandparents because of richer diets. This happens within one or two
generations and, thus, cannot be the result of genetic mutation or
drift.
As for women being shorter/smaller than men in most cultures, you still
have not answered the question from a previous post (I can't remember
from whom) about whether men are thus more intelligent than women
according to your book.
