Sažetak

The research about the impact of rubber and plastics on globalisation has led to the idea of discovering the fi rst material globalisation road. It started in Gona, Ethiopia, ~ 2.6 million years ago by the making of the fi rst stone choppers and fl akes. Three characteristic places were found where these cutters were made within a time span of a million years. This expansion of the making of stone tools we named the stone tools road. These tools were used for breaking the natural polymers, bones and animal butchering, approximately at the same time when the fi rst choppers and fl akes were made. Then follows the mechanical processing of natural polymers: wood, bones, ivory and antler, by separation of particles. According to the existing fi ndings, the oldest is wood processing, about 400,000 years. Probably the fi rst man-made fl ute was made of a young cave bear’s bone (animal polymer) some 55,000 years ago.
