European environments changed dramatically as Alpine and Scandinavian ice sheets retreated for the last time. Sea levels rose, flooding the North Sea, while the Baltic Sea formed at the foot of northern glaciers. Dense forests spread over formerly open country. Europeans now adapted to hunting and foraging in forest environments, camping in clearings and in more open woodland environments. Much human settlement was confined to riverbanks, lakeshores, and seacoasts. Here people found a bounty of fish, sea mammals, and bird life, supplementing this diet with plant foods and forest game. These Mesolithic cultures (Mesolithic, meaning Middle Stone Age, describes postIce Age European hunter-gatherers) achieved some degree of social complexity in Scandinavia, where richly decorated individuals were buried in cemeteries by 5500 B.C.E. These same cultures were the indigenous societies of Europe, farmers who first spread north and west across central Europe from the Balkans after 4500 B.C.E. | 1 |
