About abiogenesis and evolution?
Ok recently on the R&S section I answered a question on evolution and abiogenesis and I found I couldn't recall specifics. It's basically how did self replicating proteins become viruses and then bacterium? What evidences are there that they are connected? Also could you provide a nice detailed source on the experiments that replicated early earth conditions to create these self replicating proteins?
Any and all help is appreciated and will you biology experts come to R&S to help answer science questions (usually on evolution and abiogenesis) as I am sure some of you could do better explaining than I could. The religious love posting those questions to throw off atheists (they must think we're all a bunch of science buffs.)

I don't think virus's preceded bacteria. They are more like parts of the DNA/RNA replication machinery that has gotten away from a bacteria and went off on its own evolutionary path.
I just posted this about a similar question and I think it makes a much better case for how life evolved and it didn't likely start with proteins.
"Even the most primitive life on the planet today took millions if not tens of millions of years to form. It is possible it took longer but the very early fossils would suggest that it is something in that range. The early lifeforms were not like current lifeforms. They didn't likely use DNA and proteins for instance. They likely used other compounds until one lineage started using RNA for enzymes. Eventually they were modified by using amino acids to make more complex enzymes. Eventually a system was used that coded RNA to make specific amino-acid proteins and evolution found a dramatically more efficient mechanism and our line of life exploded and took over. ..."

Well, evolution and abiogenisis is dichotomous, but the experimental data, including the synthesis of artificial DNA of late, is highly suggestive. There are sites that cover this much better than I can. Perhaps, secretsause, this sites top evolutionary theorist, will pick up on this question. Go here anyway; a good site for the overall info needed.

Sounds like your'e being beaten at your own game to me.
