For example:
Men have narrower, more specific fields of vision for focussing on prey. I'm not sure, but they may be better at seeing moving objects. Conversely, women have wider fields of vision - the better for spotting predators around - and a greater ability to pick out a particular object amongst many - the better for spotting the tasty fruit in the grass, or the mayonnaise in the fridge.
Men are on the whole bigger, stronger and have greater endurance, which makes them better hunters. I'm not sure what the female equivalent is but it might include greater dexterity, meticulousness and possibly the whole communication thing.
