The corollary here is that intelligence isn't always an advantage. Or else all chimps would have evolved human class intelligence.
A palaeontologist interviewed here on Slashdot pointed out that this sort of logic only works for the apex predator, and the apex herbivore. They are constantly in a struggle to be the 'best.' For other species, you can find all kinds of weird evolutions as they find their niche in the world.
