physical condition involving high amounts of tissue on the buttocks and thighs

Steatopygia is the state of having substantial levels of fatty tissue on the buttocks and thighs. This build is not confined to the buttocks. It extends to the outside and front of the thighs, and tapers to the knee, so producing a curvaceous figure.

Steatopygia is an inherited condition of the Khoisan peoples of southern Africa. Charles Darwin wrote about the Khoisan in The Descent of Man in 1882, commenting that their steatopygia evolved through sexual selection in human evolution, and that "the posterior part of the body projects in a most wonderful manner".[1]
