    I wonder if we’d be able to see anything at all if they displayed all of the individual components and reactants flying in and being consumed, and not just the product DNA.

  2. Neuroelectronic Says:

    god works in mysterious ways

  3. well we know were here, and if we know the universe didnt always exists there must have been something before it. something not bound to time that has always existed.

  4. novellterminator Says:

    “and if we know the universe didnt always exists” That’s not a fact. We don’t know if the universe has always existed or not. All we know is what happened AFTER the Big Bang. No one says the Big Bang was definitely the start of everything. In fact, physicists are currently working on several theories as to what happened before the Big Bang. And to say “there must have been something before it… something not bound to time that has always existed” is also not a fact. It’s your opinion.

  5. “this process happens completely on it’s own with out an aid of ANY intelligence”.

    Obviously. I walk into a factory and don’t see a anyone, yet the complex machinery is running full speed. The presence of information in these systems and machines, the product exclusively of pre-existing intelligence, tells me if nothing else “intellect was here”. We now know it’s not just matter and energy. Welcome to Intelligent Design.

    And yes, it does have looming theological implications. Get used to it.

  6. No, it’s not just matter and energy, there is also information, that’s the whole point.
    Information that can encode itself.
    If it encodes itself, it may also by mistake (or not) make itself more complex.
    There are very few things that can be used to explain the process of evolution, as it is a process which complexifies and carries itself. Please do not try to counter the theory of evolution (which is ID’s agenda) with the genesis of life, as it is a different subject altogether.

  7. Can we just say that this shit is cool without debating the existence of god… I doubt any arguments via youtube comment threads will change anyones beliefs.

  8. this is deceptive of how it really is anyway. in reality these molecules are jumbling around quite randomly at extremely fast rates, they just fit in certain places, from a primitive kind of natural selection.

  9. Agreed. DNA is a 3 out of 4, error detecting, error correcting information carrying language the likes of which leaves even the best Information Technician awestruck. “Mistakes” do not complexify; they are at best a sideways movement; 99% of the time degenerative (something the repair mechanism tries it’s darnest to cut out and replace).

    ID, Darwinism; neither can explain biogenesis. My point is that by acknowledging the scope and nature of DNA, ID is at least a step in the right direction.

  10. Indeed. All KINDS of gobbledegook is acceptable in religion.

  11. sparkydaskworl Says:

    Talk of big blokes with beards in the sky is demonstratively untrue. But were we designed by an intelligent power? Depends on what you mean by intelligent. A system doesn’t indicate intelligence. It indicates logic, cause and effect. Neither are inherently intelligent. How the system is USED indicates intelligence. A non-interventionist God is intellectually redundant. Ours, if we have one, seems non-interventionist by any measure. So I don’t see what all the fuss is about. Welcome to Agnocism.

    Amen, brother :)

  13. If there were no mistakes and the copying process were perfect then we wouldn’t get older. And certain types of disease would not occur. It looks good but this video is basically rubbish

  14. MattyMatt761 Says:

    That was an excellent demonstration, especially of the Okazaki fragment replication.

  15. i thought exactly the same as i saw it, absolutely amazing, i like the colors a lot.

  16. fascinating..!

  17. Awesome! Science pwns

  18. amazing!

  19. BionicChango Says:

    sparkydasworl – thanks for verbalizing my entire belief system in one paragraph! Well said there!

  20. cool

  21. u betta be black

  22. I don’t think you’re right NUMBband. The proteins are jumbling around quite randomly at extremely fast rates, but fitting together has nothing to do with a “primitive kind of natural selection”. When two proteins that are able to fit each other come into contact in the right orientation, they fit.

    thnx

  24. This video made more sense than any picture in my biology book. Thanks, modern computer technology!

  25. featheredmusic. Iv’e been thinking about the complex chain of events that occur to create life and while im no expert in it, i do agree with you that it is physics on a small scale, but i also think that evolutionary biologists don’t make it easy for themselves by forgeting to mention laws of physics when they explain the processes. They just show one event following another on a chemical/genetic level and leave things out on a physics level.
