Growth in any species is an extraordinarily complex process,but growth in humans is characterized by a number of uniquefeatures. These include dramatic fetal growth (the most rapidphase of human growth), deceleration of growth immediately afterbirth, a prolonged growth phase during childhood, prepubertaldeceleration, and a pronounced adolescent growth spurt. Althoughsome of these aspects are shared with other mammalian species,others are characteristic only of Homo sapiens and are not replicatedeven in other primates.
The intricacy of the human growth curve (see Figure) is theproduct of an evolutionary process expressing the sum effect. . . [Full Text of this Article]
