The sling is an ancient weapon known to Neolithic peoples around the Mediterranean, but is likely much older. It is possible that the sling was invented during the Upper Paleolithic at a time when new technologies such as the spear-thrower and the bow and arrow were emerging. With the exception of Australia, where spear throwing technology such as the woomera predominated, the sling became common all over the world, although it is not clear whether this occurred because of cultural diffusion or independent invention.
