The development of new materials for use as covering or ornament has played a major role in the history of clothing. In early prehistoric times, the range of materials for clothing was small. Until about 10,000 years ago, people used animal skins for clothing. Single skins were worn as capes thrown around the shoulders; two skins fastened together at the shoulder made a simple garment. Fitted clothes, such as trousers or a parka (an outer garment with a hood), were also made from animal skins. Simple needles made out of animal bone, found in many sites in Europe and Asia, provide evidence of sewn leather and fur garments from at least 30,000 years ago. However, only with the development of textile technology did greater variety become possible.
