Gut microbiome of the Hadza hunter-gatherers
It is shown that the Hadza have higher levels of microbial richness and biodiversity than Italian urban controls, and enrichment in Prevotella, Treponema and unclassified Bacteroidetes, as well as a peculiar arrangement of Clostridiales taxa, may enhance the hadza’s ability to digest and extract valuable nutrition from fibrous plant foods.

Direct evidence is reported for Neanderthal consumption of a variety of plant foods, in the form of phytoliths and starch grains recovered from dental calculus of Neanderthal skeletons from Shanidar Cave, Iraq, and Spy Cave, Belgium, suggesting an overall sophistication in Neanderthal dietary regimes.

It is concluded that dust has overwhelming importance as a wear agent and that dietary signals preserved in dental microwear are indirect, and nanowear studies should resolve controversies over adaptive trends in mammals like enamel thickening or hypsodonty that delay functional dental loss.
