An Orangutan Learns to Fish
In 1990, while visiting a research camp in central Borneo, the primatologist Anne Russon saw an orangutan nicknamed Supinah attempt to make fire. Supinah sauntered toward an ashy fire pit, picked up a stick glowing with embers, and dipped it into a nearby cup full of liquid. Russon thought that the cup contained water, but it in fact held kerosene. Fortunately, that bath did little more than dampen the wood.
