The female pelvis has an opening that is wider and more oval in shape, since males don't usually need to worry about getting smallerskeletons through the openings in their pelvises in which i hate.


How can you tell if a human is a male or female?

One way to determine if a human is male or female is by looking at their physical characteristics, such as reproductive organs, secondary sex characteristics (like facial hair or breast development), and chromosomes (XX for female, XY for male). Gender identity is how an individual identifies themselves, which may not always align with their biological sex.
