Neanderthal palaeodiet was dependant on habitat
Saturday, May 7, 2011 | News
The choice of diet for Homo neanderthalensis was dependant on geographical location is the conclusion of Dr. Luca Fiorenza, lead author of the recently published article in PLoS ONE. Whereas previous studies assume specific dietary specializations, the team suggest that the diet of both Neanderthals and early
Neanderthal diets are reported to be based mainly on the consumption of large and medium sized herbivores, while the exploitation of other food types including plants has also been demonstrated in previous studies. Though some studies conclude that early Homo sapiens were active hunters, the analyses of faunal assemblages, stone tool technologies and stable isotopic studies indicate that they exploited broader dietary resources than Neanderthals.
Analysis of molar wear patterns using occlusal fingerprint analysis derived from optical 3D topometry. Molar macrowear accumulates during the lifespan of an individual and thus reflects diet over long periods. Neanderthal and early Homo sapiens maxillary molar macrowear indicates strong eco-geographic dietary variation independent of taxonomic affinities. Based on comparisons with modern hunter-gatherer populations with known diets, Neanderthals as well as early Homo sapiens show high dietary variability in the Mediterranean evergreen habitats while a more restricted diet in upper latitude steppe/coniferous forest environments, suggests a significant consumption of high protein meat resources.
