"About 2.5 million years ago, humans first used tools to make other tools then to make tools assembled from different parts to make a unit with particular qualities, such as wooden spears with stone spearheads (ca. 200,000-300,000 years ago.) The bow and arrow and other complementary tool sets made it possible for prehistoric humans to greatly increase the flexibility of their reactions.

"There are many basic complementary tool sets: needle and thread, fishing rod and line, hammer and chisel. The bow and arrow are a particularly complex example. The reconstruction of the technique shows that no less than ten different tools are needed to manufacture a simple bow and arrows with foreshafts. It takes 22 raw materials and three semi-finished goods (binding materials, multi-component glue) and five production phases to make a bow, and further steps to make the arrows to go with it. The study was able to show a high level of complexity in the use of tools at an early stage in the history of homo sapiens."

From the abstract:

"We show that, when isolated, neither the production of a simple bow, nor that of a stone-tipped arrow, can be reasonably interpreted to indicate tool behaviour that is cognitively more complex than the composite artefacts produced by Neanderthals or archaic modern Homo. On the other hand, as soon as a bow-and-arrow set is used as an effective group of tools, a novel cognitive development is expressed in technological symbiosis, i.e. the ability to conceptualize a set of separate, yet inter-dependent tools. Such complementary tool sets are able to unleash new properties of a tool, inconceivable without the active, simultaneous manipulation of another tool. Consequently, flexibility regarding decision-making and taking action is amplified."

Complex thinking behind the bow and arrow

The bow and arrow have long been regarded as a possible indicator of culture in prehistoric times. Bows and arrows appear to have been in use for some 64,000 years, given evidence from South Africa. U…
