If two women of the same height have the same muscle and fat mass on their legs, they should have the same bottom, right? Wrong. How wide is each woman's pelvis? A woman with a narrower pelvis will have a narrower area to place the same muscle and fat as the other woman, which creates the pop that a cute booty has. The mass cannot go left or right, it must jut out. What does science say? Black women have narrower pevlic inlets and outlets than white women. Narrower pelvis + same mass = bootylicious. Case closed. With my amateur eye, I would say that there is something different about the look of a cute booty on a black girl vs. a white girl. Black girls with nice asses seem to start with mass higher on the ass curve (where the lower back meets the cheeks) than white girls. Side note: on the internet, a white woman with a booty is referred to as "whooty" or a "pawg". I love women who are slender with curves in the right places, so it doesn't really matter to me.
Life is a bit cruel. The gifts we receive often have a negative side effect. Narrower pelvises are found more often in black women, and so are higher rates of death from childbirth. A narrow pelvis is a risk factor. Obesity doesn't help, but a girls got to keep her extra somethin'-somethin'.
