Proving once and for all that blondes are not so dumb is a new study on the evolution of hair colour by a clever Canadian. Turns out that a man shortage about 10,000 years ago in chilly northern Europe provoked women to develop blonde hair and blue eyes in order to stand out from the crowd of your common old brunette and snag a man. The brunettes had to develop the smarts to survive, while the blondes stayed in the cave with their feet up. Luckily, over the years women discovered that flashing their tits was also a good way of attracting interest, and then the world invented Tesco, which sorted out the whole hunting-for-food thing too.
