Except even before who's stronger or not reproductive biology in human already dictated patriarchy.
One man and a million woman can repopulate earth in 9 months. One million man and one woman isn't any faster than one man one woman.
When a woman is pregnant even if she is the most capable person ever lived, she will at the very least have one day or hour where she's incapacitated due to giving birth. Males do not have this condition which means their role is naturally delegated to doing stuff (luckily they happened to be physically stronger) while also mean male lives are disposable.
