From a cursory glance at this post, I don't see how your conclusion follows. I'd believe it if I saw the model and some data that supports it. It depends on how populations along the intelligence distribution reproduce, and what the variance of intelligence is of offspring along the continuum. If everyone reproduces at the same rate, and the intelligence variance of offspring is constant across the population, then I would expect the intelligence distribution of the overall population to remain the same. It seems like, given those constraints (which may or may not be true), the variance would remain the same--neither evening out nor diverging. Let me know if I'm mistaken...honestly I've only read part of the article and I only have a lay understanding of this stuff.
