ble of complex intentional communications, researchers must continue to investigate their receptive capacities, and to attempt to provide them with a communication system that would tap their productive capacities. Is interspecies communication possible? Could we someday be having philosophical discussions with a bottlenosed dolphin? Though these questions seem ridiculous, there was much debate over these questions when a medical doctor named John Lilly came out with hopeful findings of dolphin intelligence in the 1960s (Shane, 1991). In the first true research of dolphin communication and intelligence, Lilly set out to show that through the correlation of brain size and IQ, the bottlenose dolphin was perhaps smarter than humans and began a growing interest in dolphins and their language through whistles. Though dolphins are exceedingly intelligent creatures, no real scientific evidence has yet been found to totally support the many conceptions about the animals intelligence. Lilly (1966) states, A dolphin . . . naturally uses other sounds to convey and receive meaning: creaking for night-time and murky-water finding and recognition, putt-putting and whistles for exchanges with other dolphins, and even air wailing to excite human responses in the way of fish or applause. If a dolphin is copying our speech, hell copy that part of what he hears which in his language conveys meanings. Although this excerpt shows an incredible capability for dolphins to produce intelligent communication, it is findings such as these, which lack scientific support and have lost credibility among other dolphin researchers in the past few decades. Though his findings lack support, Lilly was important in bringing forth interest among people and therefore funds towards more scientifically based research and experiments that have helped us learn more about communication skills and intelligence of dolphins (Tyack et al. 1989). In order to clearly understand if dol...
