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?

It was explained to me in a human development course that precocious puberty is more common now, because body fat percentages in children are getting higher, at younger ages. Fat cells are estrogenic and release hormones which trigger the pituitary to begin puberty.
