The earliest hunters used simple wooden sticks sharpened into spears, and they then began using stone tips sometime between 500,000 and 300,000 years ago. Primitive stone tools were used to butcher animals approximately 2.6 million years ago, but most scientists believe early humans were scavengers.
The earliest evidence of humans hunting large animals comes from around 500,000 years ago, which coincides with the age of the first stone spear tip ever found. Approximately 100,000 years ago, humans experienced a wide increase in tool usage and began making different tools from bone, ivory, antler and other materials. Previously, all tools had only been very roughly carved or chipped out of stone.
This sudden technological explosion led to people beginning to produce much more effective tools and weapons, including needles and awls. These tools were particularly important in the development of clothing, as they made it possible to stitch together leather, fur and other materials. This also led to the first recorded evidence of actual fishing, as people began making barbed fishing hooks from bones.
Although the first spears were long sticks used for thrusting at animals, over time humans developed more advanced weaponry. With these advancements came axes, throwing spears and, eventually, the bow and arrow.
