Do humans exhibit territorial behavior like other primates? I have seen people sometimes stare at others -- notably males -- and then physical fights spontaneously turn up. Is this territorial? It seems it either goes two ways: One person looks at another; the other looks back and either looks away or both look away; or they both hold a stare until one or both erupt in to physical blows and try to dominate the other or fight/assault them. Is this a display of human territorial behavior? I know some chicks do it too.
I've also read that in males more so that staring can be an "alpha" or "dominating" gesture to others -- especially if a stare is held at one in response to them either turning away or provoking a fight.
This can be seen in every area, but possibly more so in clubs, bars, or certain social settings.
