I wonder if some that are wondering have really bothered to wonder. You see when I wonder about something I tend to actually use my imagination to investigate. I usually try some visualization, and come at a question from multiple angles. Have the wonderers ever actually came at their question from the position of the single celled organism that may have by chance evolved into a multcellular organism. Had they I would surmise that they would see the fatal flaw in their thinking.
The truth is that this evolution could have happened billions or trillions of times. The bacterial population of this planet is truly massive. This could literally be happening every second of every day, and none of us would have known about what happened, because we are not omnipotent. That said it still isn't the critical flaw. The simple truth is that in evolving they would go from being on a even playing field to being not only dead last on the new playing field, but also dead last on the last playing field. To be blunt that is a epic fail as far as natural selection is concerned. Ill prepared to deal with microbial attacks, and hopelessly over powered by organisms that are not only entrenched, but extremely refined. This is beyond the proverbial David versus Goliath. This is baby David versus Goliath.
This is why you will never see this evolution happen wholesale. Yes it happened in the past, but at that time in earths past getting big and complex was virgin territory. These lifeforms weren't encountering the resistance that todays bacteria would face, and more then that they probably didn't have to deal with aggressive ankle biting either. I know some think that evolution is a process that inexorably makes everything more complex, but in truth its a force like all others in nature. Sometimes it benefits, and sometimes it denies. Gravity can give you a planet, and build a star to shine upon it, but it can also smash a planet, and turn a star into a black pit in space. Electromagnetism, can give your planet a shield against radiation, but it can also kill with a bolt out of the blue. The Weak force can keep your world warm, but it can also give you cancer.
Natural Selection isn't elevating the bugs, because it is the force that keeps them down. Everything about natural selection denies the bugs the world of the large. The difference isn't a inch. The difference is hundreds of millions of years. Yes it might seem like a small jump to you, but in truth it would be like a rabbit jumping to the moon. To imply that a rabbit should be able to do that is sheer idiocy. Just as saying a bacteria should just be able to jump a biological gap this massive. I know I will just say I will become God tomorrow. I mean its obviously so easy right?
I know the wonderers probably won't ponder this even though I am sure they will say they did, but the above words describe the application of the thought process that is derived from Natural Selection. Understanding Natural Selection allows for a very powerful way of viewing the world. Which doesn't mean you have to use it for everything, but having another tool is never a burden. The more ways you have to view a given problem. The more likely you are to solve that problem.
