Schnorr,Marco Candela,Simone Rampelli,Manuela Centanni,Clarissa Consolandi,Giulia Basaglia,Silvia Turroni,Elena Biagi,Clelia Peano,Marco Severgnini,Jessica Fiori,Roberto Gotti,Gianluca De Bellis,Donata Luiselli,Patrizia Brigidi,Audax Mabulla,Frank W. Marlowe,Amanda G. Henry,Alyssa N. Crittenden +18 more
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
Microfossils in calculus demonstrate consumption of plants and cooked foods in Neanderthal diets (Shanidar III, Iraq; Spy I and II, Belgium)
TL;DR: 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.
Journal ArticleDOI
Metagenome Sequencing of the Hadza Hunter-Gatherer Gut Microbiota
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
Mechanisms and causes of wear in tooth enamel: implications for hominin diets
Peter W. Lucas,Ridwaan Omar,Khaled J. Al-Fadhalah,Abdulwahab S. Almusallam,Amanda G. Henry,Shaji Michael,Lidia Arockia Thai,Jörg Watzke,David S. Strait,Anthony G. Atkins +9 more
TL;DR: 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.
Journal ArticleDOI
Changes in starch grain morphologies from cooking
TL;DR: This work documented the changes that occur in the starch grains of 10 domesticated plant species due to exposure to different cooking methods, in order to better understand how cooking alters the appearance of the grains, and if these cooking methods might be identifiable in the archaeological record.
