• A wide array of microorganisms, including many novel, phylogenetically deeply rooted taxa, survive and thrive in extreme environments. These unique and reduced-complexity ecosystems offer a tremendous opportunity for studying the structure, function and evolution of natural microbial communities. Marker gene surveys have resolved patterns and ecological drivers of these extremophile assemblages, revealing a vast uncultured microbial diversity and the often predominance of archaea in the most extreme conditions. New omics studies have uncovered linkages between community function and environmental variables, and have enabled discovery and genomic characterization of major new lineages that substantially expand microbial diversity and change the structure of the tree of life. These efforts have significantly advanced our understanding of the diversity, ecology and evolution of microorganisms populating Earth’s extreme environments, and have facilitated the exploration of microbiota and processes in more complex ecosystems. Microbial life can thrive in extreme environments such as terrestrial hot springs and deep sea hydrothermal vents, glaciers and permafrost, hypersaline habitats, acid mine drainage and the subsurface. In this Review, Shu and Huang explore the diversity, functions and evolution of bacteria and archaea inhabiting Earth’s major extreme environments.
