Abstract (Croatian)
Na temelju istraživanja o utjecaju gume i plastike na globalizaciju došlo se na zamisao da se otkrije prvi materijalni globalizacijski put. On počinje u Goni, u Etiopiji, prije oko 2, 6 milijuna godina izradbom prvih kamenih rezala (sjekača i odbojaka). Utvrđena su tri karakteristična mjesta izradbe tih rezala u rasponu od milijun godina. To širenje izradbe kamenih alata autori su nazvali putem kamenih alata. Ti su se alati rabili za postupke odvajanja prirodnih polimera životinjskog podrijetla, rasijecanje kostiju i rezanje strvina. Slijedila je obradba odvajanjem čestica prirodnih polimera: drva, kostiju, bjelokosti i rogovlja. Prema nalazima najstarija je obradba drva odvajanjem čestica, oko 400 000 godina, a tim je postupkom načinjena vjerojatno prva frula od kosti mladunčeta špiljskog medvjeda (životinjski polimer) prije oko 55 tisuća godina.
Abstract
The research about the impact of rubber and plastics on globalisation has led to the idea of discovering the first material globalisation road. It started in Gona, Ethiopia, ∼ 2.6 million years ago by the making of the first stone choppers and flakes. 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 first choppers and flakes were made. Then follows the mechanical processing of natural polymers: wood, bones, ivory and antler, by separation of particles. According to the existing findings, the oldest is wood processing, about 400,000 years. Probably the first man-made flute was made of a young cave bear's bone (animal polymer) some 55,000 years ago.
