Abstract: Feedbacks between biological and geological processes drove the co-evolution of life and the environment. Yet, little is known of the nature of these feedbacks and the time scales over which they occurred. 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 hot spring 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.
