The appendix is where beneficial bacteria can be left undisturbed until they're needed for digestion. For the time being that is. I think the appendix has been reserved by evolution for a greater purpose not yet determined by the whole of nature.The brain, right now, may be where ideas hide out until they're required, but what if evolution has something else in mind for the brain? What if the brain is headed for a function far different than that of thought? What if all culture and civilization are just the accidental and temporary byproduct of a work in progress? Could we be moving towards a point when our backbones give way and our nervous systems no longer have any central coordinating cluster?Where am I going to put my grocery list then?
