Most settlements were probably mostly autarctic, taking care of their own food, clothing, pottery, tools et cetera. There are however clues for the exchange of goods and resources which were not present in the local environment. In the Middle Stone Age for example, certain kinds of flint and stone were exchanged, did the first farmers of the Netherlands import their stone transverse axes and bronze was later imported from Germany, France and the United Kingdom. Within a settlement, there will certainly have been small scale specialisations because the one could better make pottery or plait baskets than the other could. Bornze casting and iron smithing were probably genuin specialisations.
