Be careful about brain size equated with intelligence.
If one takes brain size = intelligent quotient
as a given, without considering that women's brains
are smaller than men's....
Believe me, you don't want to go there....
You could get savagely flamed by the 'fairer sex' or suffer
a cluttered e-mail box full of hate mail from the same.
And of course there is the fact that in nature whales
and elephants have bigger brains than ours.
As far as I know, there are no Einsteins in the Elephant
world.
