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 mean in the past people were married at 12 , parents at 13 and dead mid 20s. Are we just seeing regression to the mean?
