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?

Actually the 19th century was a bit of an anomaly. During the Middle Ages it typically happened around 12 or 13. The reason it happened later in the 1800s is probably as a result of urbanisation and industrialisation causing poor nutrition
