ONE day in 1922, near Broken Hill, Southern Rhodesia (now Zimbabwe), a skull was found. When it came to the attention of the British Museum, the curators were pleased.
It was, in fact, a Neanderthal skull, and Neanderthal bones did not exactly come ten-a-penny.
But the Broken Hill skull was special for other reasons. On the left side of the cranium was a small, perfectly round hole. At first it was assumed that it had been made by a spear, or other sharp implement, but further investigation proved that this had not been the case.
