Dolphins are rated as being superior in intelligence to domestic dogs, and some scientists have made claims that they equal or surpase the intelligence of some primates. It has also been theorized that the sounds made by dolphins are actually a language. John Lilly, an American neurologist, conducted some experiments during the 1960s to test the validity of this theory without success; however, research still continues at several universities and laboratories around the world. | Dolphins are rated as being superior in intelligence to domestic dogs, and some scientists have made claims that they equal or surpase the intelligence of some primates.
