Dolphins may have big brains but a South African-based scientist says lab rats and even goldfish can outwit them.
Paul Manger of Johannesburg's University of the Witwatersrand says the super-sized brains of dolphins, whales and porpoises are a function of being warm-blooded in a cold water environment and not a sign of intelligence.
"We equate our big brain with intelligence. Over the years we have looked at these kinds of things and said the dolphins must be intelligent," he said.
