Origins of RNA - a challenge for evolution
Good morning R.R.S. I thought I would post a topic that has been on my mind for a long time.
My recent search for understanding has led me to DNA.
It seems evident to me that DNA is the basis for life on Earth. The single code for life. Furthermore, It seems that evolution is the origin for different types of life on Earth. The common thread between life's origin and life's evolution seems to be DNA. It appears to me that this explanation seems accurate in spite of being very brief. Operating from this understanding, I have deep concerns about the origin of DNA.
[My understanding of things said here after is very limited. I have not studied chemistry or biology beyond freshman college level]
RNA is said to be the building blocks of DNA. That is explanation is all good and well. But where did RNA come from? I just finished reading a chapter in Vital Dust about this very issue and got a very disheartening answer to this question. The general opinion, although disputed among some chemists, is that RNA's origin is completely derived from chance. Not incremental stackings of chance of events, but as it appears, complete sudden chance during early non-life-sustaining Earth.
My question does have evolution as evidence for the non-existence of God debunking underpinnings, but I don't know if I can make a strong case between the lack of knowing the origin of RNA, to the debunking of all of evolutionary evidence. The envisioning I have of how RNA could possibly undermine evolution is because DNA is taken for granted in evolution and not considered derived from sudden chance. (If Mr. Dawkins does address DNA/RNA's origin and I just haven't read it, please let me know what he said.) As Mr. Dawkins points out in that documentary on evolution from BBC, evolution is not sudden chance, but slight chance modifications stacked up over a long period of time to form a not completely random thing. (Forgive me if my understanding is incomplete. Just kindly note the misunderstanding in a reply) But I see there being a problem if the process of evolution, which is guided by DNA, is essentially being undergurded by a complete and sudden random appearce of RNA.
Now again, I admit up front that my knowledge of science is amateur at best. So if you see flaws in my understanding consider them an honest mistake and not a flagrant intentional misunderstanding. Furthermore, if you feel that my correlation between DNA or RNA with evolution is not a worthy criticism of evolution please let me know.
I look forward to all replies and again please remind those who wish to reply that your comments please be gentle. I am stepping into the world of which I know very little, but want to learn more. So if on my first attempt of the riding the scientific bike, you feel that I've fallen down, just help me get back on my feet so I can try again. *Extends a gracious hand of welcome*
