Speaking of timeframe - as I was reading around I saw the "ev" program that was simulating random mutations and it was looking like the creation of just an e.coli was going to take longer than the age of the earth. So I'm not too sure we can just throw a billion years at it and call it good.
I'm not sure what you're referring to, but I have a sneaking suspicion that it's something by Behe or some other Intelligent Design advocate.
I'd like to see more tests done.
Fortunately for you, it's not like this isn't a well-studied topic. There should be plenty of stuff already out there.
I've got to break up this next sentence to unpack it a little;
Even considering the timeframe involved, we're skipping right over the fundamental origins of life itself
Yes, evolution is not the same thing as abiogenesis, though I'm sure there's some overlap in the concepts.
and what is at the source of it and the order, thoughts, feelings, emotions, and self-will that is in place that allows these genes to mutate through the generations.
I really don't understand what you're getting at here. Genetic mutation doesn't require thoughts, feelings, emotions, or "self-will." If you mean "how does evolution lead to life forms that have (or appear to have) thoughts, etc.," well, brains evolve. If you want to get into a whole mind/body dualism debate, there's a bunch of folks here who will oblige you on that.
Sure there are some strange designs but to me, that doesn't detract from the overall elegance of the mirror image amazing human body. A few jury riggings doesn't even compare.
"Mirror image" (by which I assume you mean symetrically-shaped bodies) seems to be to be remarkable
unsurprising. There's a pretty clear survival advantage to having limbs of similar length and location on both sides of your body. (And many aspects of our bodies aren't symmetrical: we only have one heart, liver, spleen, etc., and they aren't all lined up right in the middle of our bodies. Left/right brain specialization, too.)
But here's the thing. "Believing" in evolution isn't about being reductionist and saying that humans in particular, or nature in general, is humdrum and boring. When I started reading about evolutionary biology (a few years ago, as an adult; I took pathetically little biology in high school), I found it fascinating. So do the people who study it. Duh, that's
why they study it!
Here, for example, is what Richard Dawkins wrote in the preface to The Blind Watchmaker (which I'm giving a second reading at the moment):
Dawkins said:
The brain with which you are understanding my words is an array of some ten million kiloneurones. Many of these billions of nerve cells have each more than a thousand 'electric wires' connecting them to other neurones. Moreover, at the molecular genetic level, every single one of more than a trillion cells in the body contains about a thousand times as much precisely-coded digital information as my entire computer. The complexity of living organisms is matched by the elegant efficiency of their apparent design. If anyone doesn't agree that this amount of complex design cries out for an explanation, I give up. No, on second thoughts I don't give up, because one of my aims in the book is to convey something of the sheer wonder of biological complexity to those whose eyes have not been opened to it. But having built up the mystery, my other main aim is to remove it again by explaining the solution.
emphasis mine.
By the way, returning to the "random chance" thing that got this discussion started, here's the opening of Chapter 3:
Dawkins said:
We have seen that living things are too improbable and too beautifully 'designed' to have come into existence by chance. How, then, did they come into existence?
So there you have one of the big names in the field, a man often referred to as "Darwin's Rottweiler," voicing
part of the sentiments you have: that the life forms we know (including ourselves) are too complex, too amazing and fascinating, to have come about by mere chance.
Intrigued yet?
By the way, whatever you may think of Dawkins from his recent book The God Delusion, his earlier works like Watchmaker and The Ancestor's Tale, are fascinating reading on evolution for the intelligent layperson. Although he does express his exasperation with certain creationists on occasion in those books, they're hardly atheist propaganda. But you can certainly find other writers in the field; perhaps something from
this reading list

Computer viruses can and do evolve with human intervention - the virus writer creates the virus, the virus detection software detects it, so the virus writer modifies it to go undetected a little longer, exploiting different vulnerabilities. So that evolution is driven by and intelligent being at its source.
Yeah, it's not really analogous. To be comparable to evolution by natural selection, you'd have to give the virus the ability to "mutate" randomly on its own, and set it up so that viruses that successfully infiltrated their target(s) were more likely to reproduce, i.e. the "bad" mutations tend to get caught by virus detection software and don't reproduce, while the "good" mutations (rare as they might be) get through and do reproduce. But I don't think I want to torture this analogy any further.
What about arms turning into wings? Wouldn't the poor genetic line who mutated slowly along that path be killed first - half a wing, half a leg - can't run very well but can't fly either?
Coincidentally, the chapter of The Blind Watchmaker I've been reading today discusses some of those issues. "Half a wing" can in fact be useful -- ask a flying squirrel, which has flaps of skin extending between arms and legs. They can't actually fly, but they do glide.
I do want to learn - and I guess we can all learn together here if we all choose to.
Well, hey, it is an Educational Foundation, after all.
My lack of faith in the learning process was based on the evidence I had seen in other threads. Who knows, maybe this thread can be different?Thanks again for the thoughtful responses everyone.
Most evolution threads degenerate because, quite frankly, the vast majority of creationists aren't interested in honest discussion. I don't expect you to take my word for it, but if you do some digging, you'll notice that most "evolutionist" websites, books, etc. cite and respond to creationist arguments, whereas the creationists for the most part continue to spout the same lies and misconceptions. It's one thing for you to come into a thread, say that evolution is just random chance, and then listen to why it's not and genuinely think about it. Most creationists show up, barf up their standard "arguments" (Random! Second Law of Thermodynamics! The eye! No transitional fossils!), and then ignore the rebuttals and continue to spit out more long-debunked arguments, until they run out. Then they run off, presumably to another website, and rinse, lather, repeat.
Anyway, at this point I think I'm going to drop out of the discussion. If you really want to learn more, check out some of those reading suggestions. I'm sure other folks can point you to some more; I think there was a recent thread on the subject in a different subforum. It really is a cool area to learn about. Thanks for keeping things civil.
