Heterochrony

Heterochrony is a change in the speed and duration of development of some biological indices during the body's development.

Body height and morphology and the time when sexual maturity is reached are influenced by heterochrony.

Heterochrony is caused by mutations affecting the genes related to development and are one of the speciation mechanisms.
