Thanks man. Much appreciated. And I'd have one with you to. Slainte! (cheers in gaelic) St. Patricks day coming soon.
Ullopincrate;2895545; said:However there is no evolution without life. If you can't explain how life started then we again are at an impasse. period.
Ullopincrate;2895545; said:This one (fasebj) was interesting but still doesn't show me life. It's a good read but it's not proving life came from nothing. It is written with an agenda as was my chemistry story which contradicts life coming from nothing (have a read, I posted it 2x).. You, aren't qualified to argue with the guy who wrote my chemistry story nor am I qualified to argue with the authors of your post.
the_deeb;2896547; said:I honestly don't think this is fair. As I said before, evolution makes NO claims about the origins of life. If you think that evolution can't exist without chemical abiogenesis then I honestly think you misunderstand the theory. It's like saying that the theory of gravity doesn't make sense because it doesn't explain tornadoes.
the_deeb;2896547; said:So regardless of how it started, we know that it DID start. If you want to argue that evolution needs life to be relevant, it has clearly has life (regardless of origins) therefore the application of evolution is sound.
the_deeb;2896547; said:I think I know enough to say that the McCombs article that you keep citing on the impossiblity of chemical abiogenesis has a number of problems.
the_deeb;2896547; said:He uses many strawman arguments in his article (incorrectly portraying the opposing side's arguments to make them easier to refute). One of the main ones is insting that abiogeneis claims that initial life had the complexity of modern proteins and nucleic acids. Modern proteins are very complex and no one claims that they self assembled that way. Current theories on abiogenesis suggest that the first molecules to self assmemble were probably polysaccharides, lipids and ribonucleotides. A broad variety of these molecules are thought to have existed in the primordial soup and many of them have been shown to spontaneously polymerize. It is interesting that he does not mention any of these in his article. I don't know if his article is old and he was therefore not aware of these aspects of the theory or if he deliberately left them out.
the_deeb;2896547; said:He also makes a big deal out of the fact that the primordial soup must have been stable and therefore non-reactive. That would be true if it was a completely closed and controlled system but that's a comletely false proposition. A primordial soup would have covered a vast area and would therefore have been succeptible to huge fluctuations in local temperature, pH, cation and anion concentrations, UV light and the physical proximty of potential monomers and other associated molecules. These variations could easily have contributed to an environment where polymerization was sometimes favorable thermodynamically and sometimes not.
the_deeb;2896547; said:Ok, I need to get back to work.
NilePufferFanatic;2896766; said:I love the clip on page 4, the professor has a slide that skews the debate as Creation against Evolution(3:40). In science I thought we analyze one idea at a time and focused on the natural world. The debate should be whether evolution is a good vehicle to explain our world.
Good job guys on staying on topic.
