A couple of points here. - Humans have evolved. Look at our huge array of characteristic physical appearances. These differences have emerged in spite of the fact that we all share an extremely common same-species common ancestor. And that's just what's on the outside. Our primary divergence from our evolutionary (different species) ancestors has not been what's on the outside, as we've become worse in nearly every way, but what's on the inside. Intelligence > all. Discussing this topic as it relates to humans today is very sensitive. - Evolution is driven by natural selection and ultimately by who's most successful at breeding. Humanity has socially evolved in a bizarre way in that today those who are least successful tend to breed far more successfully than those are more successful. Lower income, lower education, and higher religiosity are strongly correlated with higher fertility. The Flynn Effect [1] was the observation that 'real' IQ scores were constantly increasing in developed nations. This was a major issue since IQ is normalized such that for any given population that mean is always 100 with a standard deviation of around 15. That means that somebody in 1960 with an IQ of 100 was probably more intelligent than somebody from 1920 with an IQ of 100. This was convenient for the environmental view of intelligence as improvement in environmental factors correlated with the increases in IQ. However, the Flynn effect in many developed nations has actually reversed, in spite of the continuing improvement in environmental factors. It continues to remain in effect in less developed nations. There are many ways to interpret this, but it's certainly interesting to consider it from an evolutionary perspective.
