Let me attempt what I think may be a clarification. Playing my usual 'harp', remember that this is a PMR and is a VR. The biomass is a virtual biomass and the real players of those bit parts are the low end of the spectrum of individuated consciousnesses, not fundamentally different from our real total selves, except for having a lower level of comprehension and a much smaller decision space. They, like you, take roles in PMR as part of their developmental process for their own total beings. Whether they are false starts is not really true, even if their present PMR roles are replaced by other organisms in the process of evolution. This process of evolution is the primary process of consciousness evolution. Try anything once! Follow up with the other primary process of organization and entropy reduction. If it doesn't work well, note and file the data and try something else. This is built into the rule sets of PMR and into the nature of Consciousness Space. Following the procedural basis for consciousness development does not produce failed organisms that should have never existed. It produces data as options are tested and evaluated for productivity. The real role players of individuated consciousnesses taking these parts in possibilities that did not work out retain the benefits of what was learned. They continue on participating in the next experimental design.
The colony/social insects mentioned are also experiments in consciousness organization. And the ones we can observe, the ones that work, survive and continue, are obviously successes. This is something that I see stressed in the study of biology, limited as my contact with it is. It is an example of the reiteration of the primary processes of consciousness development. You get an isolated environment, perhaps a large island or sub continent and some organism manages to get there and develop over time. That organism then proceeds to evolve and develop variants on its original conformation that puts new sub species into all the ecological niches that are not already filled. So perhaps what was originally a medium sized predator develops variants like larger predators and up to something bear like and also variants like smaller predators, scavengers, etc. Evolution puts life into every possible niche.
I wouldn't say the Fundamental Process of consciousness evolution is doing anything for or against any destructive proclivities of man. Environmental destruction happens with all species. Have you seen any documentaries showing what happens when elephants, for example, exceed the carrying capacity of their local environment? Or perhaps they are pushed into too small an area by men? They destroy their environment, just like humans do. Get too many rats in the environment and they make it unfit for rats, not to mention humans. The conclusion just hasn't come in for the human species. It probably will over the next generation and looking ahead does not bode well for our children. Unfortunately we have not been smart enough as a species to see the rocks of the Malthusian shore as our population ship approaches. There has always been a way to say it ain't so. But if our species ends up amongst the failures when the data finally comes in, we, you and I as individuated consciousnesses, will continue by taking other roles in this or another PMR. Just not necessarily as humans, but as what ever replaces us.
