White of Loyola Marymount University, and Chris Butler-Stroud of the Whale and Dolphin Conservation Society, who proposed the document during the world's largest science conference (the American Association for the Advancement of Science in Vancouver, Canada) in 2012, said dolphins should be perceived as "nonhuman persons" because they exhibit individuality, consciousness, and self-awareness.

Studies show that dolphins not only have the ability to learn as individuals, but those individuals can then pass their new knowledge onto others.
