Then I completely agree with point 2, for signaling is not just another characteristic of the cell, it is "the" eukaryotic trait par excellence.  And I am curious on how point 3 could be further substantiated... In this respect I recommend the two papers that Bill sent to the list a few weeks ago. Do we need to postulate the emergence of a form of "self-referential cognition" right at the beginning?

From the comments, it is clear that there is a strong impulse to seek a means of integrating the role of symbiogenesis, viruses and mobile elements, multilevel selection, niche construction, genomic plasticity into a common narrative with an informational perspective at its foundation.
