QUOTE : Pedaling up one of the rare hills of my native Holland, I was bracing myself for the gruesome sight awaiting me at the Arnhem Zoo. In the early morning, I had received a call telling me that my favorite male chimpanzee, Luit, had been butchered by his own kind. Apes can inflict incredible damage with their powerful canine teeth. Most of the time, they are just trying to intimidate each other with what we call “bluff” displays, but occasionally the bluff is backed up by action. I had left the zoo the previous day worrying about Luit, but I was totally unprepared for what I found.<br /><br />Normally proud and not particularly affectionate to people, Luit now wanted to be touched. He was sitting in a pool of blood, his head leaning against the bars of the night cage. When I gently stroked him, he let out the deepest sigh. Bonding at last, but at the saddest moment of my career as a primatologist. It was immediately obvious that Luit’s condition was life-threatening. He still moved about but had lost enormous amounts of blood. He had deep puncture holes all over his body and had lost fingers and toes. We soon discovered that he was missing even more vital parts.<br /><br />I have come to think of this moment in which Luit looked to me for comfort as an allegory of modern humanity: like violent apes, covered in our own blood, we long for reassurance. Despite our tendency to maim and kill, we want to hear that everything will be all right. At the time, however, I was focused only on trying to save Luit’s life. As soon as the vet arrived, we tranquilized Luit and took him into surgery, where we sewed literally hundreds of stitches. It was during this desperate operation that we discovered Luit’s testicles were gone. They had disappeared from the scrotal sac even though the holes in the skin seemed smaller than the testicles themselves, which the keepers had found lying in the straw on the cage floor.<br />“Squeezed out,” the vet concluded impassively.
