Ok, see that part i can accept and understand. I know we see it in menstrual changes in girls (age of onset), and age we live to be. So it could well make you smarter. make your brain fire better. Conversely, the chemicals around us, and lack of variety in food, and light at night make us more prone to depression, autism, etc.

I'm just really stumbling at accepting any idea that we can evolve in 100 years, without serious pressure on it.
