Just in case. Re:
Before anyone goes off halfcocked the mutations I was describing were those taking place in the individual generated by extant environment, Using that I was attempting to illustrate a process whereby genetic variation and fitness progresses over generations within a being. Obviously mutations passing from one generation to the next take place primarily in male and female DNA. There structure and location of genes relative to primary and founder genes determine most of such genetic variation. Adapted mutation and direction of fitness still normally progresses relative to environment from receptor to neuron up existing pathways to cortex over time.
However on a second note the specific frequencies signaled by a single receptor merge with that of other visual receptors into a phototropic array at cortex and perhaps at other nuclei in ascending visual pathways which also retains receptor information.
I would never rule out a probable mechanisms for how evolution takes place given the number of possibilities of gene change mechanisms. Williams syndrome is an example of radical genetic change. It's not really viable but it does illustrate the extent to which a single genetic change can rewire many features of behavior and anatomy.
Nitall. I need my Nitol.
Fitness has a starting impetus from the nature of the conditions with which it is confronted. Mutations are more likely at the periphery. Fitness works from proximal to distal, from stimulus input to stimulus response from one minor mutation to the next at a particular locus then the next relevant locus.
