the transition from not-life to life

Q: do you think the "no-life" to "life" transition... that first step to the first living cell.... was a bigger and more complex step than all of the evolution of lifeforms that has happened since?

A: the free energy way of looking at life suggests that, 1) there isn't any kind of border between life and not-life. homeostatic dynamics arise within all systems, and just progressively increase in richness when possible. there were probably lots of intermediate steps between autocatalytic RNA sets and modern "cells". and 2) each additional step is only meaningful in the context that it arose in. the organizational level of, e.g. what we call "life" is just the tip of an iceberg of systems dynamics. the right way to think of the non-living world isn't as a static or dead -- it has its own rich dynamics, upon which the steps toward life are just little nudgings that reorganize those dynamics.
