I’ve seen a study which found that the age of puberty (especially female puberty) is dropping rapidly. In 1860 it started around 16.8 and in 2010 it was 10.8. Why is that? Is there any explanation?

I can throw an anecdote at you that may answer your question. I’m not sure.
Back in maybe 2001, I, an 8 year old female, went to a pediatric endocrinologist. I had already started developing breasts. My endocrinologist determined that my bones were that of a 10 ½ year old, or a kid that was two and a half years older. As my doctor and mother were conversing, he mentioned that he “wouldn’t be suprised if the kids go into puberty earlier and earlier due to what they are putting in our food.”
I subsequently started my period exactly 2 years later, in the 5 grade.
