    Key idea 1 of 8

    Humans have always made war – and we may be genetically programmed to do so.

    Nestled in the Swiss alps is the quaint town of Bolzano. One of its major attractions is Ötzi, otherwise known as the Iceman. Ötzi is the mummified corpse of a man who lived around 3300 BC, well before the Great Pyramids were constructed in Egypt or Stonehenge was built in ancient Britain.

    How did Ötzi die? At first, archaeologists thought that he’d gotten lost in the mountains and frozen to death. But eventually they discovered something very different: Ötzi’s body was covered in cuts and bruises, and an arrowhead stuck out from his shoulder. His own knife and arrowheads had blood on them. So it seems Ötzi died in a fight. 

    His story shows that humans have been wounding and killing each other since at least the later Stone Age. But why?

    The key message here is: Humans have always made war – and we may be genetically programmed to do so.

    For decades, scientists believed that early humans lived peaceful, nomadic hunter-gatherer lives. But now, researchers are almost certain that organized, armed conflict has always been part of our existence. 

    Does that mean war is encoded in our biology? Are we genetically programmed to fight? To discover the answer to that question, scientists have studied chimpanzees and bonobos – humans’ closest genetic relatives. 

    What they’ve found is, unfortunately, inconclusive. On the one hand, chimps can be quite violent. They start deadly conflicts with little or no provocation. The bonobos, on the other hand, are seemingly much more peaceful. When two bonobos first meet, for instance, they gaze at one another, share food, and embrace rather than attack.

    So which one is more like us? The answer may be neither. That’s because, as history clearly shows, humans are capable of both extreme violence and far-reaching cooperation.

    We’re still driven by the same evolutionary forces that shaped our species at the dawn of humanity. Some of them – like the desire for food – can make us violent. But we have also, in a sense, domesticated ourselves. We can choose not to go to war, or we can go to war in service of more abstract ideas, like honor or religion. 

    Let’s dive a little deeper into reasons for war.
