Early evidence of heating stone to enhance flaking qualities

Africa in the Middle Stone Age after 65,000 years ago deliberately heated silcrete, a hard, fine-grained, local rock used in stone tool manufacture, so that they could more easily obtain blades from the core material.

A major effect on hunting

These blades were then crescent shaped and glued into arrow heads. This era, known as the Howiesons Poort, has produced the first known evidence for the use of the bow and arrow.

This is the first time anywhere that bows and arrows were used. This would have had a major effect on hunting practices as both spears and bow and arrow could be used to hunt animals,” says Professor Christopher Henshilwood.
