But why are womens pelvis’ created this way? What is the function of this design compared to the men’s design?
It is part of the overall design of a woman’s pelvis to accommodate childbirth. Apparently, a women’s pelvis is as wide as it can be on a biped because humans have very large skulls to accommodate their large brains. This design is not the most efficient design for walking necessarily, which is why males, not having to deal with childbirth, do not have the exact same design.
