Those dreadful Stone Age people

You know those Stone Age people we keep hearing about? The really thick ones whose language is a series of grunts, and who carry a club with which to hit women over the head and drag them back to their cave? The ones who keep inventing the square wheel in the cartoons?

This is a picture of the kind of thing they were making as arrow heads about 8,000 years ago, with nothing more to work with than pieces of flint and their bare hands.

Were they not truly a most remarkable people?
