> ““A large brain-to-body size ratio is often considered a hallmark of intelligence, although it’s not the only factor. But it is something we humans celebrate in ourselves and regard as key to the flowering of human intelligence. So it’s easy to imagine scientists’ eyebrows arching in surprise when dolphins—and not chimpanzees—were discovered in the 1950s and 1960s to have a brain nearly as large as our own on this scale.””
