Necessity compelled Neanderthals to dry hunks of big game meat for easy transport, according to a new study on the survival needs of Neanderthals. Neanderthals also likely wore tailored clothing, according to the new study, which has been accepted for publication in the Journal of Archaeology. The findings help to explain how Neanderthals could transport meat over long distances without it rotting, as well as how they survived the often chilly conditions of Northern Europe. According to the study, Neanderthals sported "one or two layers of skins/furs and wrapped skins/furs for shoes, held together by leather strings." Author Bent Sorensen told Discovery News that chewing clothing materials wasn't beneath these members of the Homo genus. "Neanderthal tooth marks indicate chewing hides for softening, which is essential for clothes making," said Sorensen, a researcher in the Department of Environmental, Social and Spatial Change at Roskilde University.
