Abstract
Feedbacks between biological and geological processes drove the co-evolution of life and its environment. Yet, little is known of the nature of these feedbacks and the time scales over which they occur. Here we describe a series of geobiological feedbacks that have played out over the past ~1.1 to 0.8 Ga and that shaped the co-evolution of thermoacidophiles and their acidic hotspring habitats. Future experimentation will evaluate kinetic controls on the acid-generating reactions and the physiological adaptations that allowed microbes to exploit these reactions to fuel their metabolisms.

Comments
Eric Boyd is associate professor of microbiology at MSU. He studies the geomicrobiology of rock-hosted eco-systems as analogs for microbial metabolism on Earth. Specifically, his work focuses on life prior to photosynthesis and how it diversified in response to changing availabilities of mineral-sourced nutrients. Eric was an undergraduate at Iowa State University. His Ph.D. is from MSU in microbiology.
