Transport around 11,000 BC

The Globe broad conclusion is that an advanced global seafaring civilization existed during the Ice Age, that it mapped the earth as it looked then with stunning accuracy, and that it had solved the problem of longitude, which our own civilization failed to do until the invention of Harrison’s marine chronometer in the late eighteenth century. As masters of celestial navigation, as explorers, as geographers, and as cartographers, therefore, this lost civilization of 12,800 years ago was not outstripped by Western science until less than 300 years ago at the peak of the Age of Discovery.  (America Before)

Of the several unexpected discoveries at Franchthi Cave, foremost is evidence of an established tradition of seafaring in the Late Paleolithic Aegean. Small amounts of obsidian in deposits immediately above material dated to the eleventh millennium have been identified as originating on the island Melos, some 90 miles southeast of Franchthi over open seas. Melos remained an island throughout the maximum regression of sea level (which had already begun to rise by this time), and even island-hopping the long way round, a competent maritime technology apparently was required for the journey--and for the sea-borne explorations which must have preceded the discovery of this main Aegean source of obsidian.
