Then (this was ~1990) I went back further in the process and fell in
love with the idea of Cairns-Smith on the prebiotic (possible??)
clay-life era. Here again I continued the 'creation' by my handicap of
being a colloidal scientist and drew in the Miller experiment for amino
acids (1935??) with the absorptive etc. surface phenomena of 'clay'
conglomerates (be it phospho- or simply silicato- or more diversified)
- macromolecules - (eu?)colloids and 'imagined' a mixed growth, where
the attached C-based components (call  them "organic") might have
exercised greater reactive flexibility  than those we now degrade as
'inorganic'. (I just found in Jannie's URL the ref (~2000) to
carbohydrates as well). So the arsenal of today's 'bios' grew on top of
the prebiotic claycolloids which even underwent their 'mitosis'
(cleavage by overgrowth and the formed segments refolding into lower
free energy formats, with changed reactivities what I call prebiotic
lifeprocess).

PS. Dan, is it congruent with your preference? J

I admit I don't know the clay-life origin of life hypotheses at all. But it sounds from your post that it stills uses cells as the simplest, most general and original life form - correct me if I am wrong. If so, this cellular life story would not be congruent with my hunches, which have an ecosystemic autotroph-heterotroph cycle emerging first, being the most simple, general and fundamental form of life and this process generating cells, metabolism and replication much later after many, many cycles. Cells/organisms are thus subsets or components of ecosystemic/community life, not independent examples of life in and of themselves. Thus "why life?" is not the same as "why cells?" but is the same as "why ecosystems/communities?". The answer to "why cells?" would then be "because they were generated by ecosystemic/community life via a process of "encapsulation and miniaturization" (HT Odum's terms). Thus ecosystems/communities are not super-organisms, but organisms/cells are sub-ecosystems.
