I think evolutionary change is being stifled by both medicine and civilization. Reproductive "success" is not genetic anymore, its based on social factors. The goal of most humans is no longer to spawn the most progeny.
I come from a small backwoods town and women in these areas (e.g. low income, low education) have more children, and have them at a younger age. ( This is a generalization, no anecdotes please. And no I don't feel like looking up stats, maybe someone else can post some).
Also, regardless of the details, I hope TFA is wrong. Have you seen dwarven females?
