The same growth pattern from puberty suggests that modern human diversity results from changes during pre-pubertal development

Abstract Patterns of human growth established for one population have rarely been tested in other populations. In a previous study, three growth curves from puberty were modelled for each sex in a longitudinal study of a Caucasian population based on stature, age at peak of growth and biological mat...
