We’re pleased to announce the next NfoLD webinar! Thursday, 25 June, 10:00 am Pacific (17:00 UTC) Presented by Dr Chris Kempes Sante Fe Institute (SFI)
From systematic physiology to universal principles of life
A major challenge in astrobiology is understanding the full space of possibilities for living systems. A key step in meeting this challenge is to extract the general constraints from extant life and then to use these constraints to define the full range of possibilities. Organisms are subject to the laws of physics, so the process of evolution is constrained by these fundamental laws. Classic and recent studies of the biophysical limits facing organisms have shown how fundamental physical constraints can be used to predict broad-scale relationships between body size and organismal physiology. In this talk, I will discuss systematic scaling relationships for organisms along with the underlying physical, energetic, and physiological constraints and tradeoffs that can be inferred from these relationships. I will then show how these constraints can be relaxed to define a broad range of living possibilities.
