The Paleolithic Age is a period marked by the evolution of human tools. Beginning approximately 2.5 million years ago and ending roughly 12,000 years ago, the Paleolithic Age saw human technology evolve quickly, leading to the use of tools. The tools developed by the ancient hominids were used for hunting, cooking, and eventually, burial and ritual purposes. The tools consisted of three main materials---stone, wood and bone---but degradable organic materials such as leather and plant fiber could also have played roles in tool development.
Paleolithic translates to "Old Stone Age," appropriately coined for the dawn of hominids' use of stone tools. Early versions of hammers, clubs and knives were created with carved stone. Stone would also be used to create other stone tools, such as shaping an arrowhead.
Hominids developed the need and use for wooden tools during the Paleolithic Age. Wood was used to form handles for hammers and axes, bows and shafts of arrows, and carved-tip spears. By the end of the Paleolithic Age, hominids were experts at utilizing their environment to create tools.
The bone from dead animals was an integral part of Paleolithic man's tool belt. Some uses of bone included handles for hammers and axes, needles for stitching, and knives. Though it appears bone was not a commonly used tool until the late Paleolithic Age, it played an important role.
