Not only is the boundary wall still brick, but the chimps are not alone on the other side. Dogs perform better on one kind of intelligence test than chimpanzees: “The task was to retrieve the object the experimenter wanted. To indicate which one she desired, the experimenter pointed imperatively to it and directly rewarded the subject for handing over the correct one.” In other words, dogs could understand finger pointing but chimps could not. Even though dogs do not have fingers but chimps do.
For that matter, grey parrots and ravens have been shown to solve puzzles that were formerly reserved for primates. Does that make them closer to humans than other birds are? As close as chimps are? If not, what is the point of studies that attempt to trace the evolution of human abilities by studying those of chimps? The possibility of independent origin of the tested types of intelligence is clearly demonstrated by clever birds, separated from us in evolution by hundreds of millions of years, or so we are told.More.
