Don Jose, the age old debate of "nature vs nurture" is this: "Nature", meaning you/we were born with certain tendencies, tastes, etc... "Nurture" means .... no, you weren't born with them, but as you grow up, people around you, your parents, teachers, siblings, etc... form your tendencies and tastes.
So the person who sides with "nurture", would say that little girls tend to play with dolls, instead of toy trucks, is because they are conditioned by having them put in front of them, steered to like them d/t subconsisious suggestion from their mothers, playmates, etc... Same for little boys and trucks. They only gravitate towards them not because of something in-born, but because of subtle suggestioning by their dads, peers, etc...
But if you side on the "nature" side of the debate, you would say that there is a biological reason why men and women think diffently, gravitate towards different jobs, hobbies, toys, etc...
