'Dumb' dolphins

Dolphins may have large brains, but a South African scientist says lab rats and even goldfish are smarter than them.

Paul Manger of the University of Witwatersrand in Johannesburg said that the big brains of dolphins, whales and dolphin dolphins have only one function to keep their blood hot in the environment.

cold water, not a sign of intelligence.

"We equate our big brains with intelligence. Over the years, we consider all of these traits and claim that the dolphin should be very smart."

"The real problem in this logic is that it argues that all brains are designed in the same way . But when you look at the brain structure of a dolphin, you see it is not created for those too. complex information handler, " he said.

As a neuroscientist, the Manger's view will certainly cause a disturbance in the community that has long been attributed to dolphin characteristics such as intelligence, affection and other human characteristics. . They are considered one of the smartest species. But Manger said the truth was different.

The brain, he said, is made up of neurons and glial cells. These buffering cells create an environment for active neurons and heat generation is one of their functions.

"The dolphin has a lot of glial cells and very few neurons. Its brain is not evolved to process information - it is designed to deal with temperature challenges when animals live in their lips. Water School, " Manger said.

Manger also said that the observed behavior supported his new view of the dexterity of dolphin dolphins.

"You put an animal in a box, whether it's a mouse or a gerbil, the first thing it wants to do is climb out. If you don't put a lid on the bowl, there's a goldfish, It will also try to jump out to expand its living environment, " he said.

"But a dolphin never did that. In the marine parks, the separators are only a few dozen feet above the water between the different pools."

Why so? Because according to Manger, simply that thought is not in their poor thinking.

Dolphins jump over the rings at the performing parks just because they have reflections that will receive food rewards.

Dolphins can actually sequence up to 16 behavioral responses to stimuli, but that only proves that they are well trained and not a smart creature.

And if they're smarter, they won't get caught in the fishing net, Manger said."If they're really smart, they just jump over the net because this net is still completely underwater."
