Compared to the Neolithic, the Palaeolithic people had a far less complex technology. They used basic stone, bone and antler tools and developments such as art and other forms of "higher culture" only occur in the later stages of the Palaeolithic.

Exchange and trade networks were also comparatively more developed.</span>
