Dolphins are dumb
Dolphins may be highly spiritually evolved, but it appears that they're not too bright
, being even less intelligent than goldfish, or so claims Paul Manger, of the University of the Witwatersrand:
"Dolphins have a superabundance of glia and very few neurons... The dolphin's brain is not made for information processing it is designed to counter the thermal challenges of being a mammal in water," 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 it will eventually jump out to enlarge the environment it is living in. 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."
They jump through hoops only because they have been conditioned to do so for a food reward - which may suggest the brain of a single-minded predator rather than a reasoned thinker.
Manger also makes the point that, if dolphins are so smart, why do they get themselves killed in tuna nets?
