Just because you don't like the process does NOT mean that isn't the way the world works. I suggest you spend a little time actually observing nature (either in the woods or via. cable nature channels). "Mother Nature" IS "red of fang and claw".
Also, your understanding of the evolutionary process is flawed--SUCCESSFUL mutations survive--only unsuccessful ones get "pruned". Is this a wasteful process?? Yes. Unfortunately, that IS the way it works.
It's not that I do not like it, it is just that it does not work that way from where I am seeing it, period. I choose an axiom, you choose yours. Don't impose your crap, I wont impose my own bath water.
But I guess your heart is into final solutions, so be it.
No such pruning occurs. D'ambricour proved that there is a mechanism that allows "chance" mutations to follow a strange attractor. Just as a tree grows branches by chance but in a coherent way because of the strange attractor, so do the "mutations". Why this strange attractor is programmed we do not know, but what it tells is that the "undesirables" should not get pruned, except in extreme cases, because they are just as capable as desirables to branch off into something better. "Nature" just does not throw the baby away with the bathwater.
4 -2 does not equal 6 no matter how much rhetoric and pseudo-scientific nonsense you and other evolutionists say. You do not create anything by destroying things, you do not create new genes, functions and abilities by destroying them. Evolution has been a joke since the word go.
