That isn't true. Feel free to tell me what the alternative theories that constitute competition to abiogenesis. The alternatives are pretty much 1) a deity or 2) some mythical life force assembled things.
Abiogenesis has a ton of evidence behind it, but we do not have the entire chain of conditions and reactions required to go from primordial molecules to actual fact. Much in the same way that 'AI' vanishes, as we develop evidence and establish facts that support abiogenesis, they become standard biology, chemistry or physics.
Compare the argument for abiogenesis in the 1800s to the one today. We've discovered the mechanism for generating our species from single celled life forms, we've determined that RNA have intrinsic catalytic ability, we've developed robust theories of non-equilibrium reaction processes.
As for your statement about junk DNA, you have a very limited understanding of what that actually refers to. Junk DNA refers to non-coding dna. We know those areas can influence chromatin structure, contain regulated control sequences which influence gene expression, contain splicing sequences, etc.
As for your last paragraph, you make it very clear you don't understand the subject you're talking about. I suggest doing more than reading pop science books and picking up a volume on molecular biology. It will clear up what I imagine are a legion of misconceptions you have about what we know.
- oldandtired 9y agoWhat is not true? You made one statement then you made a contradictory statement. It matters not that neither of the alternatives that you supplied are palatable to your thinking processes. You cannot prove the veracity of your belief system by any scientific method as they are metaphysical in nature. As I pointed out above, try listen to James Tour and you will see much of your "ton of evidence" is really evidence. It is conjecture and may have some evidential value, but on the basis of actual processes, the "evidence" just doesn't stack up. We have in no way discovered the mechanism for turning single celled lifeforms into our species. If we had, we should have no problems in doing this from any sample of single cell lifeforms other than our own. We can't and we don't. I don't consider any of the dna to be junk. I am using the definitions as promulgated by those who ascribe to the idea of "junk" dna. By your own definition as given above, this means that the relevant "junk" dna is not "junk". As for my last paragraph, it is a consequence of the evolutionary model. You can argue that it is not a consequence of the model but then you would be arguing against the evolutionary model itself. Since I took a great deal of interest in this area in my younger days and I would read as many of the published experiments as I could. What got me looking at this further was the discrepancy between the reported results of these experiments and the purported conclusions reached by the experimenters. My last sentence is accurate, if you cannot test and reproduce the outcomes/results then it is just conjecture. So with those comments, what is your background, interest and expertise in these areas?
- ABCLAW 9y agoI don't think an extended back and forth will be very fruitful at this time. You have very large misconceptions about what we know, because you've approached the subject to look at a point of interest without understanding the context of the evidence we have. It's laudable that you're looking into things, but you have clear, demonstrable, gaps in your knowledge. It's as if you're trying arguing against the existence of rocks by pointing at pebbles and erosion while forgetting you're standing on a mountain littered with boulders. I know this message must come off in an abrasive manner, and I do apologize. That isn't the intent. It is just difficult to show you precisely where you're wrong with the finite time I have available to me. I can't be your personal tutor for the natural sciences, but I feel an obligation to future readers to put your comments in context. If you're serious about learning about the subject, pick up a molecular biology textbook and start reading, or audit a few 101 level courses at your local university. Molecular biology is great because you will get a huge bang for your buck in terms of understanding the natural world with your very first few classes!
