And they range from a rate of almost a 60 percent chance that a man will die at the hands of another man to, in the case of the Gebusi, only a 15 percent chance. The tiny, little blue bar in the lower left-hand corner plots the corresponding statistic from United States and Europe in the twentieth century, and includes all the deaths of both World Wars. If the death rate in tribal warfare had prevailed during the 20th century, there would have been two billion deaths rather than 100 million.
Postoci su u rasponu od gotovo 60% vjerojatnosti smrti kao posljedice ubojstva do, u slučaju Gebusija, samo 15%. Mala plava crta u donjem lijevom kutu označava odgovarajuću statistiku za SAD i Europu u 20. stoljeću i uključuje sve smrti u oba svjetska rata. Da se smrtnost plemenskog ratovanja održala i tijekom 20. stoljeća, poginule bi dvije milijarde ljudi, umjesto 100 milijuna.
