mrmoshe Posted August 20, 2006 Posted August 20, 2006 CONTROVERSIAL research claiming dolphins are marine dimwits rather than among the most intelligent of animals has split Australian scientists. The scientific and marine conservation communities were divided yesterday in response to a South African academic's research showing dolphins are less intelligent than lab rats or goldfish. The study, by the University of the Witwatersrand's Paul Manger, claims the large brains of marine mammals such as dolphins and whales are to help cope with being warm-blooded in cold water and not a sign of intelligence. He argues the dolphin, widely regarded as one of the smartest mammals, does not display enough sophistication in its behaviour to show any more intelligence than a lab rat or goldfish. "When you look at the structure of the dolphin brain you see it is not built for complex information processing," Professor Manger said. "You put an animal in a box, even a lab rat or gerbil, and the first thing it wants to do is climb out of it. If you don't put a lid on top of the bowl a goldfish will eventually jump out. "But a dolphin will never do that. In the marine parks the dividers to keep the dolphins apart are only a foot or two above the water between the different pools." Why not? Because, Professor Manger says, the thought would simply not cross their minds. Australia's Dolphin Research Institute conservation director Jeff Weir said people tended to get angry when new evidence came to light about dolphins' character. "There's something special about them that has fascinated people for thousands of years," he said. "But there's little evidence they're as intelligent as everyone wanted to believe. "It's not consistent with what people want to believe - and they get upset when it's not true." Geneticist Dr Bill Sherwin, from the University of NSW, said groups of dolphins now being studied showed the most complex social behaviour outside the human realm. "They do have pretty complicated behaviour. There's nothing complex in chimpanzees, orang-utans or gorillas," he said. "I've worked with a number of different species and dolphins definitely look like they're thinking about you, and reacting to you and other things in their environment. "This is compared to another species I worked with, the bandicoot, where you could stand there and they would repeatedly run into your legs. "When you watch dolphins interacting in groups, it's like watching office politics. The male alliances constantly change - it must take some sort of brain capacity to do that sort of thing."
Penguin Posted August 21, 2006 Posted August 21, 2006 (edited) Im not sure about Dolphins not being as smart or clever as a lab rat, this professor came to this opinion bcoz,Dolphins dont jump out of the water and over a devider into another pool,but a rat is smart bcoz it can jump out of a box if it doesnt have a lid. Would you blame a Dolphin if it didnt want to leave an environment that it is comfortable in and leap thru the air to land in another pool that is hopefully full of water,and know that while it is in mid air it has no control over where it lands,and knows that if something were not right it cant just simply slam on the brakes in mid air and turn back to where he came from. Would a rat leave his comfortable box if he had to dive underwater, and under a devider and come up on the other side again to get to another box? I doubt it.But I have seen them walk up to cats,Goannas and snakes and have a quick smell of these predators,just before the lights went out.Thats real inteligent. penguin Edited August 21, 2006 by penguin
abiasin Posted August 22, 2006 Posted August 22, 2006 who care whether they are or are not, as long as they stay away from my boat when im fishing, cause when they come thru they scare everything off. thats my 2 bob cheers.
