Are humans getting dumber?

Here's a good conversation starter by an under-employed expert digging at the roots of our collective family trees going back to just after we came down from those and began walking on our knuckles, grunting a lot, and learning how to make a good dinosaur casserole, while avoiding being captured by those Wild Women of Wongo and dragged kicking and scratching back to their settlement along the crocodile infested banks of the Limpopo River in darkest Africa. It was called 'darkest Africa' of course, because Ben Franklin hadn't yet flown his kite and discovered electricity can be a shocking invention.

Want proof we're getting stupider? Just ask yourself how a nation like America could have possibly convinced themselves to elect someone like 'Dubya' not once but twice. Twice! Shouldn't the first time have taught them something? If that isn't proof that we're getting stupider, I don't know what would do it. And don't forget what 'Uncle Albert' said: "The commonest element in the universe is not hydrogen, but rather stupidity."
