Researchers identify possible link between the environment and puberty
A possible epigenetic link between the environment and pubertal timing has been discovered by researchers. To a large extent, pubertal timing is heritable, but the underlying genetic causes are still unexplained. Researchers have now studied how chemical modifications of the human genome (so-called epigenetic modifications) change when girls and boys enter puberty. The results indicate that such epigenetic changes are involved in defining the onset of puberty.
