Everything I have read, early puberty has nothing to do with giftedness. One study showed that girls living with the non-biological father entered puberty early. It was a natural selection type of thing where a girl living with her biological father entered puberty later.
Also, almost all countries have been experiencing earlier onset of puberty, including China, except Scandinavian countries.
And a lot of it is genetics. I entered puberty at 13, despite being with girls a year older at school. My mother was late also.
Obesity is a large factor. Fat has more estrogen, hence why we get belly fat at menopause.
