Dolphins May Be Dumber Than We Think
excerpted paragraph:
"For more than 50 years, the dolphin has been viewed as an especially intelligent creature, grouped together with human beings and great apes. But now a dispute on the subject has erupted among scientists, and the smart aleck of the seas may end up being just an average mammal. "We put them on a pedestal for no reason and projected a lot of our desires and wishes on them," says neuroethologist Paul Manger of the University of the Witwatersrand in South Africa. According to the professor, the claims that dolphins have a particularly complex brain, use a sophisticated language, are self-aware and can use tools are nonsense."
Well, I don't think he was being serious - check his 'nom de plume'.
Well, further down in the article it say this.
“To put it bluntly, most of that is bullshit,” says Karsten Brensing, a marine biologist with the organization Whale and Dolphin Conservation (WDC) . . . “You can use similar arguments to prove that people aren’t intelligent.”
