We tend to think of warfare as a uniquely human trait. After all, although animals do attack and kill each other, this is usually all a part of nature’s circle of life and death, right? This seems to be all fighting over territory, food, or mates, at the whims of their natural instincts, and there is usually little thought given to the fact that animals might wage premeditated war with each other, taking sides and engaging in strategy like us. Yet, humans don’t seem to be alone in our capacity for power struggles, alliances, and flat out war, and this can be seen with the spooky case of a group of chimpanzees in Africa that began a full-fledged civil war, which remains the only witnessed such incident of its kind.
