Although there is a wide range of normal ages, girls typically begin the process of puberty at age 10 or 11; boys at ages 11— For boys, an androgen called testosterone is the principal sex hormone. While testosterone is produced, all boys’ changes are characterized as virilization , a substantial product of testosterone metabolism in males is estradiol. The conversion of testosterone to estradiol depends on the amount of body fat and estradiol levels in boys are typically much lower than in girls. The male “growth spurt” also begins later, accelerates more slowly, and lasts longer before the epiphyses fuse. Although boys are on average 2 centimetres 0. Most of this sex difference in adult heights is attributable to a later onset of the growth spurt and a slower progression to completion, a direct result of the later rise and lower adult male levels of estradiol. While estradiol promotes growth of the breasts and uterus , it is also the principal hormone driving the pubertal growth spurt and epiphyseal maturation and closure. The hormonal maturation of females is considerably more complicated than in boys.

Use of this concept, together with a reanalysis of the fossil record, moved the estimated time of the evolutionary split between apes and human ancestors forward to as recently as about 5 mya. Since then the molecular data and a steady trickle of new hominin fossil finds have pushed the earliest putative hominin ancestry back in time somewhat, to perhaps 8—6 mya.
