PLOS ONE—When fluctuating climates in the Ice Age altered habitats, modern humans may have adapted their diets in a different way than Neandertals, according to a study published April 27, 2016 in the open-access journal PLOS ONE by Sireen El Zaatari of the University of Tübingen, Germany, and colleagues.

The Neandertal lineage survived for hundreds of thousands of years despite the severe temperature fluctuations of the Ice Age. The reasons for their decline around 40 thousand years ago remain unclear. The authors of this study investigated the possible influence of dietary strategies using the fossilized molars of 52 Neandertals and Upper Paleolithic Homo sapiens (modern humans). They analysed the type and degree of microwear on the teeth to attempt to draw conclusions about diet type and to establish a relationship with prevalent climactic conditions.
