Old news.... here let me explain it in one word....
Testostorone.
It's the gender changing hormone. It makes complete and thorough physical changes to all aspects of the human body. A fetus not exposed to it, or ARD (Andro Resistance Deficincy) I think that's the right term, will not become male. ARD means that while normal amounts of testostorone are present, the body is resistant to it's effects and a woman is born but completely sterile due to DNA still being that of a man. One X and one Y chromosome.
As stated, this hormone changes all aspect of the body including the brain. The brains of mean are overall bigger, and weigh more but are also more compartmentalized. Which means there is less connecting tissue between areas of the brain so they function more on their own and with less influence then other sections of the brain. This is need for situations that males have historically been used for. Fighting is one of them. To function with the over presence of some emotions, the parts of the brain that need to work through some overiding emotions like fear, anxiety, pain, and others need to be able to shut off from other sections of the brain. This is also why men overall have a harder time dealing with emotions then women. It is also why men's concentration on a SINGLE task can be greater then a woman.
Women's brains are smaller, but denser due to more connective tissues such as the corpus collosum. This allows more parts of the brains to talk and work in concert together which allows for multi tasking but lack of concentration and easier confusion and allows emotions to dictate actions.
There are much more differences between the sexes in terms of physiology in the bodies and brains. They are there because of the roles were are suppose to play. Men are historically the hunters, protectors, and the "weaker sex" in terms of sucseptability to disease, mutations, dying of old age, and degenerative disorders that are passed down. This is because they have an X and Y chromosome and if one is screwed, they don't have a backup. Women have 2 Y chromosomes and if one is screwed they literally do have a backup.
Men and women can never "truly" be equal because there are just somethings men are designed by nature both physically and mentally to perform that women can't do and vice versa. I'm not just talking child birthing but that's the majority of where their skills are needed and have been developed for. If you are a creationist, then we were created differently and for evolutionists were evolved differently into our roles for survival.
This also explains why some fields are predominated by men and some by women. There are exceptions to every rule, but they are not the norm. Jobs and tasks which rely heavily on focusing on one subject and concentration are going to be easier for a man to complete then a woman. Computers, engineering, mechanics, chemistry, and trauma surgeons for example are almost going to be jobs done by men. Some jobs, like doctors, are going to have both men and women but since there are different specialities of jobs a doctor can be, certain ones will be for men or women predominately due to natural abilities. As stated, you are more then likely to have a surgeon as a male but a pediatrician as a female.
I'm not saying either gender roles, abilities, and limitations are good or bad. Together, we make a whole. Men and women are two halves of the same coin and one is needed for one set of jobs most of the time and the other is needed for another set of jobs. Together we get everything done.
