Macaques can be found all across Japan. We followed a troop on a small island in the country's northeast and discovered some amazing greeting rituals and dietary habits. Also on display were the power dynamics found in any tight-knit group. The alpha male role has its privileges but breeding preference is not always one of them. And no matter how strong a macaque may be, it pays to have friends. Close observation revealed that all the infighting and other drama are not so different from our own.
