>Is the emergence of life an expected phase transition in the evolving universe? Depends on whose expectations you are trying to meet. To some it would be a major transition, to others it's just another everyday minor non-event in the very macro scheme of things. If you're going to look at it mathematically it probably makes a difference when the number of non-extreme planetary environments begins to become significant compared to the number of possible chemical reactions among the limited number of elements in nature. Only one of these numbers can reach truly astronomical proportions.
