Hi A few days ago a interesting thought stroke me during my chemistry lesson. I don't know how I started thinking about it, but i just thought that prokaryotes may not really be living organisms, but rather just a system of elements and molecules and a many many chemical/physical reactions. One can't really say prokaryotes are intelligent and they are the simplest cells known. Maybe all their actions are just triggered by the quest for the lowest energy level (what initiates all reactions, i.e. molecular boundings, quantum jumps of orbiting electrons to a lower energy level if one is free, etc). (Although they are still extremely complicated when described completely on a molecular or atomic level) As I thought further and furhter, I know can't see any differences between an organic and living organism and a large quantity of chemical/physical reactions (neglecting complexity now, no doubt that organisms are by far more complicated) What do you think about it?
