Maybe because IQ is the result of a huge number of interacting genetic factors, and is thus unlikely to experience substantial drift over the existence of the human species? That would differentiate it from e.g. melanin production or lactose tolerance, which are heavily determined by only a few genes, and thus more likely to respond to selective pressure.
