Transition from Early to Late Stone Age
The transition from Early to Late Stone age is dated to about 4500 BC. Further south the Late Stone Age is also called the Neolithic period, which is the period when agriculture started to gain a foothold. In the north agriculture came later – here in Varanger animal husbandry was not common until 1600 AD.
Even if the transition to the Late Stone Age evidently did not create any drastic economic changes in this area, something happened that has left traces in the archaeological material. This includes among other things changes in stone technology –how they made their stone tools.
While people in the Early Stone Age almost exclusively used knapping techniques and hard stone species such as quarts and quartzite, the grinding technique was introduced in the Late Stone Age. A suited material for this proved to be slate, and in the settlements from the Late Stone Age there have been found arrow heads, spear heads, knives, axes and chisels made of slate, with finely sharpened edges.
Another change between Early and Late Stone Age was the way houses were constructed. In the Late Stone Age period the houses became more permanent, which indicates that people became more settled and stayed in the same area for longer periods of time.
