Experts remind that human physical development is a very complicated process, from top to bottom, from near to far. The head develops the earliest. The head length of a newborn is 1/2 of that of an adult, while the head length of a newborn is 1/4 of its own body length. In contrast, the development of lower limbs is late, and the newborn is only 1/4 of that of adults at birth. Therefore, the development of long bones of lower limbs after birth has the greatest influence on height.
