An interesting aspect of their results lies in the stratigraphic occurrence of the bone tools. While Leakey and Shipman identified bone tools in all the beds, they identify, with one possible excep- tion, bone tools only in Bed II. Knapped bone tools appear more systematically, according to their results, in coincidence with the appearance of remains of Homo erectus in middle and upper Bed II. The presence in a Bed II site of an intentionally knapped bone hand axe constitutes supplemen- tary evidence that Homo erectus was responsible for the production of at least some of these bone tools.

Not only does this discovery help the archaeologists study the technique used in making the tools but it shows the kinds of foods people ate during that period.

Among the 17 tools, there were six spear points which dated back about 34, years and were believed to be used for hunting animals. Interestingly, there were a few barbed points found in the group. Archaeologists believe that they were used as harpoons. These harpoons dated about 23, to 18, years ago. Not only is it interesting that their tools changed over time, but this also means that they hunted animals on land and used the harpoons to start fishing as another way of providing food. Shuangquan Zhang, said that the harpoons were the oldest weapons to have been found outside of Africa.

He added that the cave had records of the oldest bone tools from China, which include the oldest known barbed point tools made outside of Africa.

Stone Age man wasn't necessarily more advanced than the Neanderthals

Zhang explained that the changes in hunting tools could have indicated that there was a desire to change the foods the ancient people were eating. The theory is that at first they were eating smaller mammals, then they decided to switch to fish.

However, it cannot be proven until there is more analysis done on the tools. A collection of twenty-eight bone tools were recovered from 70 thousand year old Middle Stone Age levels at Blombos Cave. Careful analyses of these tools reveal that formal production methods were used to create awls and projectile points. Archaeologists have long believed that Neanderthals learned how to make bone tools from modern humans and by mimicking stone toolsviewing bone as simply another raw material.

Modern humans, on the other hand, took advantage of the properties of bone and worked them into specific shapes and tools. A recent discovery of specialized bone tools at two Neanderthal sites in southwestern France brings to light the idea that Neanderthals may have actually taught modern humans how to make specialized bone tools.

The uncovering of lissoirs "polishing stones" at these sites is significant as they are about 51, years old, predating the known arrival of modern humans to Europe. Bone folders are still used by bookbinders. Awls[ edit ] An awl is as a long, pointed spike generally used for piercing or marking materials such as wood or leather.
