TL;DR: 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.
Journal ArticleDOI

Simone Rampelli,Stephanie L. Schnorr,Clarissa Consolandi,Silvia Turroni,Marco Severgnini,Clelia Peano,Patrizia Brigidi,Alyssa N. Crittenden,Amanda G. Henry,Marco Candela +9 more
TL;DR: The first metagenomic analysis of GM from Hadza hunter-gatherers of Tanzania shows a unique enrichment in metabolic pathways that aligns with the dietary and environmental factors characteristic of their foraging lifestyle, providing a better understanding of the versatility of human life and subsistence.
Journal ArticleDOI

TL;DR: An improved method is used to survey common foods for free and glycosidically bound forms of the nonhuman sialic acid N-glycolylneuraminic acid (Neu5Gc), showing that it is highly and selectively enriched in red meat and is bioavailable, undergoing metabolic incorporation into human tissues, despite being a foreign antigen.
Journal ArticleDOI
Small-scale societies exhibit fundamental variation in the role of intentions in moral judgment.

TL;DR: There is substantial cross-cultural variation among eight traditional small-scale societies and two Western societies in the extent to which intent and mitigating circumstances influence moral judgments.
Journal ArticleDOI
Old stones' song: use-wear experiments and analysis of the Oldowan quartz and quartzite assemblage from Kanjera South (Kenya)
