Do Dolphins Recognize Their Reflections?
Diana Reiss at City University of New York has been studying animal intelligence for over 25 years. Does the intelligence of a dolphin rival that of a human? "We used to think we were the only species on the planet that could think, and now we know that we are amongst many thinking species", Reiss stated. She added, "the question is no longer can they think, it's how do they think".
