How intelligent are Dolphins?

During the past few decades, scientists have intensified their efforts to better understand the Dolphin mind. This research led to a groundbreaking milestone in 2001. A study conducted at the Wildlife Conservation Society’s New York Aquarium demonstrated unequivocally that Dolphins are self-aware, a complex, cognitive capacity previously known only in humans and great apes (Reiss & Marino, 2001). But just how intelligent are they? The short answer to this is that we do not yet know. There is no reliable method to measure intelligence in humans across cultures, so it is not surprising that comparing humans, Dolphins, apes, dogs, etc. is impossible. There are some indications of their potential: they are fast learners and can generalize (which is also true of pigs, by the way). Also they can learn to understand complicated language-like commands (which is also true of the great apes).
