It seems to me that semiosis is a complex process consisting of at least
three basic steps that constitute a mathematical category:
f g
Object ------> Sign ------> Interpretant
| ^

h
Figure 1. A model of semiosis as a mathematical category. f = sign
generation; g = sign interpretation; h = information flow. The
composition condition, namely, f followed by g leads to he same result as
h, holds.
Clay mineral surfaces forming templates for "catalyzing" complex chemical
reactions is an attractive possibility which alone is insufficient for
semiosis but may constitute an essential component of semiosis, e.g., Step
f, where object is mineral template and chemical reactions are signs (?)>
With all the best.
