Why are Asian American women shorter than young Chinese women？

[AFP]

Length my guess is an adaptation to climate the closer to equatorial Africa the longer the length the further away either north or south it decreases. My guess is there is some benefit it keeps bacteria further away from the bladder the closer to the equator the more bacteria because of more heat. You don't need a lot of length in northern China colder and windier climate. More likely for it to get frost bite and rot off.
