Wel, in my line of work I have drawn one conclusive substance between genders in their natural state of being. All you need is Lube - John Lennon

The answer is right there in the first paragraph you're quoting...

Men and women aren't equal biologically speaking, duh. Different roles evolved from when humans lived in caves. That doesn't mean those ancient roles are still relevant to modern society. Contrary, nowadays language and management skills are very good qualities to have outside the cave.

"Men and women aren't equal biologically speaking"

what does this mean? that men used their strength to keep women subjugated?

Not that that hasn't happened and still happens, yet it was more innocent in ancient times.
You can't hunt while pregnant, the roles were easily assigned by nature.

B --- WHY men and women's brains are different.

Human brains evolved differently for cave-men and cave-women.

Rather than just have people laugh at sex differences with jokes about "dumb blonds" or "boys toys" which involve ridicule, I would prefer to understand how male and female brains evolved very logically, and each has its advantages and disadvantages. I see ignorance about these male-female brain differences as the main cause of marriage problems.

Early humans developed some unusual traits for good reasons. As the jungles of eastern Africa changed to grasslands during a long drying spell, jungle apes designed for trees were at a disadvantage in catching food. Evolution favored walking upright which allowed more use of hands and arms for using tools.

1. Cave-MEN evolved their animal right-brain talents, such a visual spatial, into advanced abilities in hunting, fighting, design, inventing, using tools and operating equipment.
The left brain language tends to be less developed, ranging from grunts and shrugs to dyslexia.

2. Cave-WOMEN evolved brains (and bodies) for talking and nurturing in a family

1. Nurturing instinct. Most mammal babies grow fast and become independent within a year. Baby horses can walk within minutes, run within hours, and follow the herd within a day. The important point is that by next Mother's Day most female mammals give last year's baby a cold shoulder, kick him out of the nest, and give birth to the next little one. Little Bambi didn't give mom many clover leaves after getting the boot.
   But as humans evolved larger brains, female humans had a problem -- the larger brain meant larger heads and more labor pains. Women solved the problem by organizing the first labor strike. Early cave-women began minimizing labor pains by having babies more premature with smaller heads and under-developed brains. (Too premature and the baby would die. Not premature enough and the mother would die. Nine months was the compromise agreement after a million years or so of contract negotiations.)
2. Body talents. To be successful at raising children with larger heads, women needed wide hips for birth. Cave-women also evolved a shoulder design that made it natural to carry a baby while nursing, but in the process their shoulders and arms were not as good for throwing spears (or baseballs, etc.). Cave-men idolized women who would produce lots of children so idolized wide hips and breasts. Also, if their wives were fat, that told their neighbors that the man was a good hunter. The earliest human figurines are called "fat venuses." Roman statues of "beautiful women" showed them as very plump, showing them to be from a rich class with a rich husband.
3. Management talents. This premature birth meant mom had to become domestic, good at managing a cave. Even at nine months the baby has so much growing to do before it can be kicked out of the nest that mom has to say no to the going on with the husband's "business trip" of a mammoth hunting. And mom has another baby next season, along with other children still hanging around the nest until they get married off. With many things happening in the cave, including cooking the food, disciplining or feeding the children, caring for the old people, talking with all of the people, and sewing up leather clothes, women developed management talents to juggle the many activities and people.
4. Language talents. Many family members in a cave led to lots of interaction, so women developed good language skills to manage the people and for teaching ideas to the young children. Grandmothers who told stories to their grandchildren about ancestors, legends, history and morality are a main feature of most cultures. (Grandmothers are so important for passing on skills and stories that in one First Nations group on the west coast of Vancouver Island in western Canada, "if there was not a grandmother the young woman would be given traditional medicine to prevent her from having children." -- from the nuuchahnulth.org stories)

Men went on to assume that everything outside the cave was their domain. Yet as people started living longer, schools were invented and hunting turned to sport rather than survival, these ancient roles were no longer necessary. Yet it took until recently that the status quo was broken. It's less than a century ago that women were even allowed to vote. I would call that subjugation indeed.

Nowadays we laugh over things like the Good wife's guide (which might be a mock up, but I've seen all that stuff separately in old books), yet when my parents went to school it was still normal to teach the girls house keeping and cooking, while the boys did crafting etc. Less subjugation, more indoctrination.

Woman have better language skills, but even today most top sellers book writers are men. Talking a lot and about a lot of subjects isn't necessarily all of better language talents. You could say that on hunting men developed more efficient communications with body and voice.

so... are you not proving here with all of this information about the differences between men and women that its possible as a result that men are better leaders?

i think that the reason for women casting off their chains from only about a century ago had less to do with indoctrination and intimidation or whatever and more to do with the industrial revolution

because as you should know life in the past was nothing like the life we experience now.... work didn't involve sitting in an air conditioned office in a soft chair typing away at a computer

work involved hard labourious tasks and as i think you would cencede women would have been less suited to working in these conditions for various reasons including that they are physically weaker and they can become pregnant

however when the industrial revolution came around pretty much just before the rise of first wave feminism, work got much much easier on the body and we started using machines to do various tasks

imo this opened up the work market for women and allowed them to become independent since they could work alongside men in various fields since work had become lass physically taxing

i don't think that people who claim it was because of indoctrination really understand what the work environment was like before we started using machines

How did you come to that conclusion? Women are better at managing and keeping track of the overall picture, next to having better communication skills. Men are better at focusing on details. Men might be better generals, Women seem better suited at leading a company or country.

First of all communication skills is not the same as book writing skills.
Part of the problem is book reviewers are predominently male and books by male authors are preferred by publishers.
But perhaps men are better at staying focussed on a single plot line and books by women are too complex for men to read :)

It's even worse in tv than in book.

Perhaps better to pander to the lowest common denominator. Got to spell it out for men to understand :p
