A new book called "Are Dolphins Really Smart?" by Justin Gregg, a zoologist with the United States based Dolphin Communication Project posits that dolphins might not really be much smarter than the average mammal.
It is commonly assumed that dolphins are one of the smartest species of animal on the planet.
But a new book called Are Dolphins Really Smart? by Justin Gregg, a zoologist with the United States based Dolphin Communication Project says that dolphins might not really be much smarter than the average mammal.
Paul Manger, a neuroethologist from the University of the Witwatersrand in South Africa says that dolphin intelligence has been attributed because of behavioral traits like having individual signature sounds, or the size of their brain, but really these things do not denote a superior intelligence to other animals.
One reason that scientists classify dolphins as being intelligent is that they have a large brain size for their body, but Manger thinks that the majority of their brain is made up of glial cells that only work to keep the brain warm in cold water.
Manger is quoted as saying: “The essential features of complex neural processing of information, as observed in other mammals, are missing or poorly developed.”
According to Gregg and Manger, displays of intelligence from dolphins have also been exhibited in other, seemingly less intelligent species.
