That argument is based on the idea that these cultural practices were, to some extent or another, deliberately created. It seems to me, based on what I have read, that such ideas as agriculture and unequal distribution of power were accidental developments slowly evolving towards recognizable forms. By those ideas, it is probable that women, usually being more involved with the harvesting of plants, had greater responsibility for the rise of domesticated crops. I doubt that there was any intentional creation of agriculture by either gender.
