Seasonal diets, seasonal microbiota Among the Hadza of western Tanzania, a few hundred people still live in small groups as hunter-gatherers, reliant solely on wild environment for food. Smits et al. found that these reflects availability different types food (see Perspective by Peddada). Between seasons, striking differences were observed their gut microbial communities, with some taxa apparently disappearing, only to reappear when seasons turned. Further comparison diverse urbanized peoples revealed distinctly patterns community composition. Science , this issue p. 802 ; see also 754
