During the
Atlantic period, the climate warmed and
broad-leaved tree forests covered much of the territory. The migrating reindeer, mainstay of the
Paleolithic hunters, retreated to the North and were followed by forest animals. The people adapted to the changed environment. They were still nomadic, but traveled shorter distances and stayed in the same place for longer periods. The archaeologists found small camps used just once and larger camps to which hunters returned repeatedly. These camps were usually located near lakes or rivers. The people used to hunt with arrows and spears and fish with harpoons. The
flint tools of Mesolithic Neman culture were influenced both by
microliths from southeastern Europe and macroliths from northern Europe (
Maglemosian culture). Therefore, the culture was initially called Microlithic–Macrolithic culture to avoid confusion with the already established Neolithic Neman culture. Despite variety of influences, the culture was rather stable for 2500–3000 years indicating no significant migrations. Therefore, the artifacts are rather unvaried stock of arrowheads, trapezoid blades, oval axes. ==Neolithic==
