Why can't things exist just because they work in our reality and are able to exist?
'cause that wouldn't be any fun to debate!:D
Anyway, I think that is somewhat of a moot point. As far as I can tell, "simple" life and in-between forms SHOULDN'T work in our reality! Obviously many people here will disagree with me, but I'm just trying to make a point. Yes, the universe is here, and yes we exist (well, unless you're a Hindu or Buddhist, but that's a different story), but the argument is whether the rules as we know them allow for life to occur through the rules described by evolution.
I am curious about one thing though. I am perfectly aware that natural selection is the method by which evolution is supposed to work. However, how does natural selection work? I know that it's "survival of the fittest," but what is the method by which the survival value of a given organism can increase?
There are two main methods that I can see. One, genetic modification (resulting in a physical change). Two, behavioral modification (resulting in something akin to modern instincts). These both obviously go hand in hand. After all, how on earth is a bird to learn how do use its physical state (its wings) without the behavior (instinct) that makes it want to flap?
The thing is, even the instinct has to come back to genetics at some point. After all, not all behaviors are learned via the "monkey see, monkey do" method. And obviously not all of them can be trial and error.
I have personal experience in some of this, through some of the poultry raising my family has done. ALL chickens at some point start scratching and pecking the ground. This behaviour cannot have been learned from watching their momma, 'cause we've artificially brooded many of them, and kept them seperate from all other age groups, up to and past the point in which they start scratching.
My point is, if it's genetic, it HAS to come from somewhere. And as far as I can tell, mutation is the only way (not counting artificial manipulations) in which genetic information can be modified. Of course, if the storage of behaviors and instinct is contained in some genetic way, I suppose that there COULD be a carrier for such information to become part of a species permanent genetic structure. But, that's only a completely unproven guess, based on almost NO evidence. And that only partly explains an alternative to mutation.
And another thing that has confused me, how is it possible for the sum total of genetic information to increase? That is, mutations result in the change or loss of a genetic "program." How is information literally added to the lengths of DNA that make up the genetic structure?
Please, don't get mad and in a huff has others (on different boards) have. My questions are honest, and I actually HAVE been trying to find answers through my own research. As I've been typing this, I have been looking through websites on synthetic theory, and neo-darwinism for methods of natural selection that don't require mutation as a source of change. But, I haven't found one yet. Maybe I'll find one, but if you have the answer...
While I'm here, I'll just give my views on evolution vs. creation. I am a young earth creationist. While I generally wouldn't argue with theistic evolution, I don't believe it to be true, mostly for personal reasons. Since we're dealing with God, I do believe it is completely and utterly within his powers to use evolution as his method of creating live. But, I have to choose between that, and young earth, and I chose young earth, because it makes more sense to me. Atheistic evolution is what I have my beef with. But don't get me wrong!!! I DO NOT argue against evolution out of spite. I argue it for other reasons. The one that applies to my current post has to do with fun. I enjoy a good debate, even though my debating skills aren't very good:)
Ah well, this post has grown WAY too long for my tastes, so I shall conclude for now.
Ya gotta love rabbit trails:D
*edit*
I just found a place that's talking (albeit at an extremely simple level) about how a mutation can produce a recessive gene. While this could explain how harmful mutations aren't always immediately fatal (either in the literal, or in the sense of natural selection), it doesn't completely solve the problem. It also brings up several other questions, but this is beginning to get too involved for it to be fun for me at the moment. Maybe at a later date, but you can still discuss it:p
