Microbiome Evolution

DNA analysis of dental tartar

Human microbiomes are influenced by nearly every aspect of human life, including diet, medication, cultural practices, ancestry, and environmental exposures. Our researchers are trying to untangle how microbes – bacterial and otherwise – and their interactions with other microorganisms evolve as part of this complex web of interactions. Researchers in our Center using ecological, genomic, and ancient DNA methods to explore the evolution of microbiomes over time and space.
