Planetary Systems Biochemistry: Inferring the laws of life at a Planetary Scale

Sara Walker

Arizona State University

Currently, no general theory exists that explains what life is. While many definitions for life do exist, these are primarily descriptive, not predictive, and they have so far proved insufficient to explain the origins of life, or to provide rigorous constraints on what properties we might expect all examples of life to share (e.g., in our search for life in alien environments). In this talk I discuss new approaches to understanding what universal principles might explain the nature of life and elucidate the mechanisms of its origins, focusing on recent work in our group elucidating regularities and law-like behaviour of biochemical networks on Earth from the scale of individual organisms to the planetary scale.
