Acceleration in human development process is the phenomenon which has been registered in many populations around the world. This applies equally to the growth of certain anthropometric parameters and the speed of reaching sexual maturity. These facts illustrate the results of secular changes in body height and appearance of the first menstruation (menarche).〔Hatton T. J. (2013): "How have Europeans grown so tall?"; ''Oxf. Econ.

The newest data set for the average height of adult male birth cohorts, from the mid-nineteenth century to 1980, in 15 European countries was studied. During a century average height increased by 11 cm representing a dramatic improvement of this phenomenon. It is interesting that the apparent acceleration of body height occurred during the Ĝ Also, in the mid-nineteenth century young European women's menarche occurred at the average age of 16.5 years. One hundred years later, this age was reduced to under 12 years.〔Boaz N. T. (1999): ''Essentials of Biological Anthropology''.
