I am not interested in Darwinian Evolution, or Social Darwinism, only EVOLUTION.
EVOLUTION is just a word; nothing more. If this confuses you then I suggest looking it up in a dictionary. Biological evolution is a scientific theory, social evolution is not. Do societies evolve? Well, they do change and some are definitely more successful than others, but I would hesitate to equate this process with darwinian evolution. For one thing, changes in society are not always random and, practically speaking, they aren't really adapting to their environment in most cases, but reacting to INTERNAL pressures. In any case I would like to repeat that this would not be a science in the same sense that biological evolution is. It's all speculation at this point.
Stop calling it a theory please. It's a fact.
You obviously aren't familiar with scientific terminology. In science a theory is a hypothesis that is well supported by evidence. Biological evolution is a theory; so is gravity. In science the only facts are empirical data, all explanations of that data remain theories no matter how well established they might be. The reason for this terminology is because science is always open to change. If scientists found enough data to refute the theory of biological evolution (unlikely, I know, but I'm being hypothetical here) then they would renounce it and try to come up with a new theory.
However, back to evolution. World War 1 for example. We may talk about the immediate cause but it says nothing for how this behavior developed in evolutionary time. We may come up with explanations about what brought on WW 1 but to understand why war exists we must look to evolution for an explanation. These two explanations are not competing with each other. They must support each other and both must be understood to properly comprehend the event. How does evolution dictate the everyday decisions of humankind?
Google evolutionary psychology. Also, I think Islamic extremism would be better explained in terms of memetics. the 'meme' is a word coined by Richard Dawkins and is supposed to be the mental equivalent of a gene. Just as selfish genes compete with one another for dominance, thus driving the process of biological evolution, memes are ideas which compete with one another in the minds of human beings. Islam could be considered a meme, as could any religion or ideology. Successful memes encourage their hosts (human brains) to reproduce them either through writing, word-of-mouth or conquest. Since Islam contains the imperative to convert the entire world using any means necessary, it might possibly be the most successful meme ever conceived.
As for your contention that evolutionists cannot "have their cake and eat it too"? You are being silly. I can fully recognize that evolution best explains the variety of life on this planet and possibly human behavior as well, without having to condone every instance of it. Just because it is true that spiders evolved, it does not follow that I should love spiders. Even if evolutionary psychology could explain antisocial behaviors like rape, genocide and terrorism, I am not obliged to condone these actions any more than a Christian would condone Satan's actions because he was created by God. I don't understand how you could make such an illogical leap.
