Have you noticed how many systems are cyclical? That means things seem to go in cycles. How about the seasons or the tides. There are generally three classes of time function systems. Those that start, expand and seem to cycle a few times before they gradually die out. Those that start,expand and keep cycling and expanding until they crash and die out. Finally, there are those that start, expand and seem to go on cycling forever. There are not a lot in this final class if you keep the clock running long enough. I want to use this model to see if I we can understand the future of us humans on the Earth.
We started out for some single spark in the distant past and over time evolved into a smart animal that has the ability to change his environment and benefit by those changes. I am thinking about growing food and animals or making fire and steam for engines, that sort of thing. I am not sure we were all that smart right after that first spark, but over time, the dumb ones of us died off, were killed or eaten by the rest of us. It was a tough place and few survived long enough to breed new humans, but the one who did were smarter. This went on for a very long time before the humans got to the point where they could build fires and kill and trap animals bigger than themselves. Eventually the smart ones figured out how to grow their own food. Us humans were kicking butt.
Now, we know a lot more about genetics and know that in those chains of DNA that it is possible to produce all kinds of human variations, but over time, only the smartest of us humans survived. The problem is that within those DNA chains are the original humans that we sprang from. Those genes are sitting there waiting to create more humans just like those original ones. If it were not for the hostile living conditions of the past the dumb ones would not have gradually died off. What we are evolving into as humans as 99% of all random gene matches take place is that we are canceling the natural evolution of the past. Don't think so? We have more people living and breeding with birth defects than any other time in modern history. I is a certainty that us humans will have more health problems and cost in the future as a result too. Hard to think about these types of things, much less write about them. You have to admit that these are the facts of the end game.
Let me tell a little short story. I watched a TV show where they were looking for the "real" domestic dog. They were looking for one that was not the result of selective breeding. We have thousands of dogs that all look very different, yet we know that they all originated from just a few original wild dogs. Seems impossible when you look at how different dogs can be, but it is a fact. In the TV show, they went all over the world looking for this "real dog". They looked in poor areas and in garbage dumps and places where the affects of human selection would be minimum and they did find the "real dog" and they all looked the same all over the world. They were a little like the Australian Dingo with a short coat and a tail that curved up over their backs. The snout was a little longer than most of our common dogs. The TV show pointed out that if nothing were done by us humans, over time, our dogs would devolve back to that "real dog". How is that?
Let's try another one. Over the past 100 or so years us humans have developed milk cows that can produce several times the milk cows just 50 years ago could produce. The point is, however, that selective breeding has to continue just to "maintain" the high level of milk production. We can't just stop. Why do you think that we keep having dog shows and that sort of thing? The dairy breeders claims that if cows were allowed to breed randomly from this point, the production would go down about 10% per generation. The point that I am trying to make is that it is like pushing a cart up hill. If you stop pushing, the cart will roll back down.
Now back to us humans. Due to forces that we haven't noticed, us humans have gotten quite a way up that hill and the hill is getting steeper all the time. If we crash and I am sure we will, it is just a matter of time. What do you think will happen? I think that with the current system where the dumbest among us do most of the breeding, we are devolved the human race. When we crash, it will wipe out many of the stupid among us and we will be back near the beginning starting a whole new cycle. In modern times when the Greek system crashed what happened? When the Egyptian system crashed what happened? When the Roman system crashed what happened? When the Inca and Aztec systems crashed, what happened? This one is going to be a lot bigger and it is going to take us back a lot farther. Don't think so? I am not sure I want to be around to see if I have what it will takes to be a survivor. How confident are you that your kids have what it will take to be a survivor? Heavy questions. If us humans are not a one shot deal, we will evolve back much the same way as we did it this first time.
For the pass couple of hundred years, we have had "do gooders" of different types running around the world helping humans who are less competitive continue to reproduce. It is a sad thing to have to say, but all the "do gooders" have made life on this planet worse and it is still getting worse. Think about the "end game" once in a while.
