Re: Re: Corpus Callosum. Hoo boy! is right!
I guess we will have to say that the jury is still out on this one (and on most of the other research findings in this area). I might also be inclined to go with Johns Hopkins, not just because it has been rated as the finest research hospital in the country, but also because the JH study is the most recent. But hey, who knows?
And JUST in case some of our boys out there picked up on the "larger male brain size," let me throw a little preventive cold water on any speculation they might be tempted to indulge in:
The brain of the sperm whale weighs 7,800g, the elephant's weighs 7,500g, man's weighs 1,500g, the dolphin's 840g, and the brain of a mouse weighs 0,4g. If these figures are used to determine intelligence, then the sperm whale and the elephant are five times as intelligent as man, who in turn is twice as intelligent as the dolphin, which in turn is 2,000 times as intelligent as a mouse. Should we rank animals in order of how large their brains are in relation to their body weight, then the mouse would come out on top with its brain comprising 3.2%, the dolphin's 0.9% and the sperm whale's 0,021%. Neither absolute brain weight nor the relationship between brain weight and body size provide us with sensible criteria for comparing the intelligence of different species.
