[The “coding” lies in the cell’s response to the stressor, if the response allows the cell to survive then it survives and reproduces its attributes, including the “coding.”]

The concept you’re suggesting is that all advancements to higher forms (although there could also be lower degredation as well) come from stressors increasing information in cells, and if that were the case, then we would be able to demonstrate evolution from one species to another through experiments. Also the problem comes in that only species specific changes can happen to gene coding for which the species has been already coded to accept- if evolution through gene changes through stressors to cells were a reality, then we certainly would be able to demonstrate this process today- but the fact is that we can not demonstrate any addition of NEW non species specific changes that would result in new organs and systems that are unique to other species only.

Again I must point out that not all advancement in evolution hypothesis is based on stressors- those who beleive in evolution contend that environmental pressures necessitate adaption that leads to evolution- this need isn’t a direct stressor on the suppsoed systems that some say evolved such as first feathers then wings (although I’m not sure what the pressing need to fly was when so much food is available on the ground- but that’s another story). So supposedly, added information comes from environmental induced needs that urge a species to only accept mutational mistakes that would advantage them- although one really needs to ask- since evolution supposedly takes millions of years, wouldn’t those ‘needs’ be changing in all that time while a species awaited their feathered wings? If the need to evolve is so great at a given time, and it takes millions of years to evolve something like wings, then it would seem that those individuals that could overcome the fact that they didn’t their required wings in time would have no logner needed wings because they would have found other resources to survive.

Interesting reply--I'll only get to part of it tonight.

You might find it it interesting to read Hans Selye's works: General Adaptation Syndrome; Stress, Distress and Eustress (I think that's the order in the title.); The Stress of Life (His most famous work.)

Environmental pressures are stressors.

Consider Walter B. Cannon's concept of Homeostasis, an idealized steady state of a given organism's physiology where all is stress-free: no hunger, no cold, no thirst, no distress, etc., etc. The fact is the organism, in maintaining its own life in an ever-changing environment is constantly working toward homeostasis but, of course, never achieves it because of the rapid flux of changing conditions, both internal and external.

but the fact is that we can not demonstrate any addition of NEW non species specific changes that would result in new organs and systems that are unique to other species only.

Say what?
