What traits are considered "masculine" vs "feminine" (among humans) and how much does this change from culture to culture?

Females are associated more with jobs that allow them to be in one (or very few) places throughout the course of the day. Not surprisingly, this has to do with child rearing. What they lack in mobility, however, they make up for typically in the variety of tasks that are assigned to them. 

On the flip side, men tend to venture further away from the home base. This is seen in activities such as hunting, fishing (from boats) and even in the wage labor system (which is now becoming more blurred as a gender specific activity due to increasing industrialization). These activities that are "masculine" are also those that individuals tend to focus, or specialize in, because this situation opens up the potential for a more single minded focus than the situation of the typical female role does.  

Gender roles do vary between cultures, but the basic idea of women being more constrained to the household because of child raising, while men (unconstrained) take on the jobs that require more travel. A good example of this would be Pacific islander men fishing for weeks at a time on the ocean from vessels, while the women of these cultures fish from shore as a sort of dietary supplement.  

Some traditional farm based chores will vary from place to place as well. For example, who tends after small animals verses large animals, or who is associated with the different stages of the agricultural process.   

edit: very to vary.
