Why Transitions FROM and TO? Why not just "It is as it was, and has always been".
Life (as we perceive it) is a consequence of design/happenstance.
The transition from chemistry to biology is a phenomenon that is only apparent in the mind of you, the reader.
Biology is chestry, is physics, is mechnics, is quantum physics. The Universe and its "features" does not categories, but some features tend to dance together, in an interesting "life" like way.
