Nice idea, but I think unlikely to pan out. One of the things that the
coral-algal symbiosis does is adjust the population -- and in some cases the
identity -- of the photosynthesizers as a function of light level, so there is
a significant amount of feedback between the insolation and the response or
sensitivity of what we think of as the sensor. And that is all within a
single host species, of which there are many.... So qualitatively and in the
very big picture there is a relationship, but nothing likely to satisfy a
*PS: I am (or was) one.
