As a former evolutionary biologist, I want to believe everything is based on biology (that's my world view), but even I recognize that most purported differences simply aren't.
If you do some more reading on the subject, you will see this is not the case.
Women are born with more sensitive hearing than men, there could be many evolutionary reasons for this, but I do not have evidence that they are the cause.
But still, women have more sensitive hearing because their inner ear that actual vibrates, vibrates more than in men. But also because of this, their hearing is more vulnerable to environmental damage. But since older women still have better hearing than older men, you could assume that women either are subjected to less environmental noise damage, or their hearing exceeds that of men enough that even though they receive more damage from environment noise, they still hear better than men.
There is many many differences between the sexes and races.
I really do not understand how people can recognize easy differences between the races like skin colour, facial features, general body size, but then deny that there is any other differences in our brains and how we perceive things.
