Microbialites were likely the first biological communities on Earth. Understanding them allows us to ask and answer questions about the evolution of communities, complex life, and the role that environment plays in community structure and composition.

Sumner’s lab group is currently addressing these topics through their work in the lakes of McMurdo Dry Valley in Antarctica as well as on Archean microbialites.
