Evolutionary Processes

Understanding the process of biological evolution, not simply from the perspective of individual organisms but also from the perspective of entire ecosystems, is an important focus of ESI. Researchers within the program are active in studies aimed at constraining the origin of life on Earth (and elsewhere in the Solar System) and the pace of biological evolution through geologic time. Studies of modern biological systems focus on the connection between life processes at the molecular level and the dynamics of the biosphere on a global level.
