A Dolphin By Any Other Name
SloppyElvis writes "CNN is reporting that scientists have proven that Dolphins can communicate with each other by name. From the article: 'researchers synthesized signature whistles with the caller's voice features removed and played them to dolphins through an underwater speaker' to which the mammals responded. This form of identification in language was previously only known to exist in the human world." Thankfully they still haven't evolved opposable thumbs.
My parents own a pet store, and move a pair of African Grey Parrots between work and home every day, along with two dogs. The birds not only recognize their own names, but they appropriatly name the dogs when they encounter them. In addition, they can tell them to sit by name and even will give the dogs bits of food in exchange for treats - they appear to do this appropriatly when they want to either cause mischief or gain obedience from the dogs when the dogs are frightening them. The birds also use eachother's names appropriatly - and at the pet store seem to know the difference between these specific dogs and the other similar dogs that they encounter.
Intelligence and symbol identification/use definitely seems to me to be a general phenomenon larger than mammalian life.
It would be interesting to repeat similar experiments with intelligent species of wild birds to see if they generate unique sound identification that they may use to identify third-"persons" non-visually in some way. Most likely birds would use such ability to immitate eachother for social manipulation - but the conclusions of the use of such symbolic proto-language would still be meaningful.
