I was taught in college that girls reach puberty earlier now than in prior centuries in part because they are exposed to light for more hours per day thanks to electrification, and puberty is in part triggered by an internal clock keeping track of how much light you’ve been exposed to in your lifetime.
Of course we leaned a lot of shit in college before the internet which turns out to be nonsense now. But I believe exposure to light is more important than we generally recognize. If you trace our evolution back to the beginning, you’ll find light sensitive cells far far earlier than anything involving actual vision.
Oh? What’s his supposed correct age for this?

Girls are having puberty without the consent of their congressmen?!
Growth hormones in meat and dairy may also have had an effect, but I have nothing to back this up currently.
Let me know if it’s completely incorrect.
I looked in to it briefly, and it seems the growth hormones are a boogie man, but dairy consumption is still a factor in early menache.
Turns out kids that have too much dairy in their diet are often overweight, leading to early menache.
