Recent archaeological investigations in Poland, at the Krzyz 7 and the Dabki 9 archaeological sites, open discussion about presence or extend of human networks in the Baltic Europe at the both 9th and 5th millenium BC. By networks, it is meant here transports or transferts of goods, ideas or technology that can possibly be highlighted by archaeological studies, by means of reconstructing human behaviours. It concerns all kind of human activities that have generated a displacement or exchange of people or objects. With no written nor iconographic sources on these last european prehistoric societies, networks can be trace via the archaeological artefacts; their raw materials, the nature of the goods (animals or objects), the shape of the items, the way they were manufactured, the associate items and their destination (grave/sanctuary/hunting camps…), together with the associate features (archaeological structures, other industries, distribution patterns…) within define regional contexts. It implies also a large scale of observation with consideration of the regional paleogeography, reliefs of which might have played an important role in the distribution of networking. It includes thus numerous contemporary sites of main regions around the North-and the Baltic Sea. Bringing out networks for prehistoric Holocene societies will unearth understanding the type of relationships that eventually occured between human groups at the 9th millenium BC in the North of Europe, and the circumstances implicate in the start or the extenstion of economic trade overseas or across lands at the 5th millenium BC. This might finally enable us to rediscuss as well what prehistoric archaeology means by « cultures ».
