"It's not all relative"

And who determined the laws of nature?

Probably whomever determined the laws of god, so I guess I'll stick with that being unknown, wouldn't want to be arrogant and presumptuous and claim things I can't know, that would be silly.

My understanding is that the bone structure and musculature of the women is almost identical to the mans except her pelvis and pelvic floor differs to accommodate child birth. Beyond that physically the construction of body is identical. An archaeologist bereft those parts of a skeleton may have real difficulty sexing the remains. It is mostly done by making a guess based of the development of the muscle and in children they can't even make this poor guess.

Physical development is also strongly affected by physical activity. It has been statistically proven that fathers seem to be more protective of female babies and toddlers than males and that females get less physical activity as a result. Such early habits are likely formative both to the bodies structure, its chemistry and behaviour in later life. The question of whether women raised in a society where they are expected to compete physically with men would develop comparable physical prowess is an open one.

Its one of the reasons I have no intrinsic objection to the notion of women in military combat roles or unisex competition even in aggressive sports.

What of the neurological differences? It's true there do appear to be small differences in the size and development of certain brain regions among the sexes but the brain like the muscle is not a static entity and will change with use and upbringing. By the same token these differences are only an average. People who have conditions such as autism and even dyslexia usually owe it to some under lying variation in brain morphology. Differences that make the small variations between the sexes look miniscule. If we are to say dyslexics have less in common with non dyslexics than men and women have with each other then how much store should we really put in the argument that there is some in born difference in the temperaments of men an women.

I would argue that beyond sexual function there really is no intrinsic difference between men and women.
