So, the theory goes, the Solutreans paddled from Ice Age Europe in kayaks perhaps as early as 18,000 BCE using methods similar to those of modern Inuits – camping on ice floes, drinking water from icebergs, and burning blubber for heat. The Solutrean toolkit, which included sewing needles and fish hooks, certainly could have been used to make waterproof clothing and watercraft from animal skins. Eventually the American descendents of Solutrean immigrants met up with the people who crossed from Beringia, and the Clovis technology was born. But as with the coastal route theory of Beringia migration, the difference in modern sea levels prevents a direct search for archaeological evidence. However, evidence of an entirely different kind, from the study of genetic origins, has added interest in the Solutrean Hypothesis.
