This article explores the proposition that the archaeological record of small, remote islands with scarce resources reflects the intensity of long-distance interaction in prehistory, taking as an example the Adriatic offshore islands. The best represented periods, the early Neolithic and the end of the Copper Age, correspond to the times of large-scale stylistic unity, the former, of the Mediterranean Impressed Wares, and the latter, of Bell Beakers. During those periods, radical innovations were introduced over vast areas of Europe, first, a new subsistence economy, and second, a different kind of social organization. In both cases, long-distance interaction would have played a crucial role.
