How do growth spurts actually work, and why does such a drastic jump in height/size not happen at any other point during human development?

In: Biology

The surge in hormones during adolescence affects the brain as well as the body. In adolescence, growth spurts prepare people for reproduction, like by making female bodies better able to support a baby, etc. And male bodies stronger probably for evolutionary hunter purposes.

Babies develop even faster for their first few years

The short of it is that your hormones surge as your body preps to begin reproduction. Before puberty, your body is focused on its own survival. After puberty, your body is focused on reproducing to create more humans.

The hormone surge during puberty causes the rapid development of your sexual organs, and because of how your endocrine (hormone) system is constructed, the sex hormones are tied to growth hormones so you grow as well.
