Children are entering puberty younger than before, according to recent studies, raising concerns that childhood obesity and hormone-contaminated water supplies may be to blame. However, our archaeological research suggests that there’s nothing to worry about. Children in medieval England entered puberty between ten and 12 years of age – the same as today.
If anything, perhaps better first world lives may be pressuring the age down a bit, but even then it sounds like there’s a lower limit. Evolutionary effects are also certainly at play as well.
