    >>>Chris Cogan: ... Thus, Bertvan's argument ends up undercutting her own
    position, because, if organisms *were* designed, there'd be no need whatever
    for such a degree of adaptability to changes in genes; each set of genes
    could be *precisely* tuned from the start so that every part would work
    *perfectly* with all the
     others, and thus never need to adjust to errant genetic changes.

    *******************
    DNAunion: This is false (or at the least, you left out something that I was
    supposed to know from following the discussion between Bertvan and you:
    sorry, I go back and pick up posts one at a time sometimes). For example:

    Chris: "if organisms *were* designed, there'd be no need whatever for such a
    degree of adaptability to changes in genes".

    DNAunion: This is true if one holds that each organism was designed as it
    currently exists and was intended to remain static also. It is not true in
    other cases (for example, if the original cells on Earth were designed, and
    then evolution took over): it would make *sense* to design in adaptability
    from the start.

    Chris: "each set of genes could be *precisely* tuned from the start so that
    every part would work *perfectly* with all the others, and thus never need to
    adjust to errant genetic changes."

    DNAunion: But researchers have designed into some computers the ability to
    evolve by running through numerous, numerous "random mutations" followed by
    selection: that ability to "adjust" was a *desirable* trait and they went out
    of their way to accomplish it. (I am referring to the evolvable circuits
    using FPGA, or field programmable gate arrays: they gave that system great
    flexibility, intentionally, by design).
    *************************************

    >>>Chris: The fact that there is such flexibility does not, of course
    *prove* that there is no designer, but it certainly argues against the need
    for one, and makes the designer (in yet another way) superfluous.

    ******************************
    DNAunion: No, it makes the designer superfluous for "everyday evolution"
    only. How did life itself arise and obtain the ability to evolve? You need
    to explain this by purely-natural means before you can make a designer truly
    superfluous (well, then there is the issue of anthropic coincidences).

    Many of your statements require that you first be handed a living organism.
    You then claim that evolution of that preexisting, functioning organism is
    possible by purely natural means and there is no need for a designer. Don't
    you see the logical flaw in that? Where does the living organism come from?

    For example, you recently presented a long post in which you drew an analogy
    with computers undergoing changes. Great, so how did a computer come into
    existence and become capable of evolving? How does the ability for a
    pre-existing and functioning computer to evolve make a designer superfluous?

    Did some natural process separate oxygen from silicon in sand to form pure
    silicon, with some of the pure silicon having aluminum and other having
    phosphorus impurities added, and these 3 forms then lined up in NPN and PNP
    style, with potential differences running across the emitters and bases, with
    the output channeled into the collector, all to form transistors by purely
    natural means?

    Even if we grant that the generation of the "monomers" is plausible by
    naturaly means (which we shouldn't), did millions of these "buliding blocks
    of computer life" then just happen to become arranged in the correct
    orientation, all hooked up and interconnected properly, as to form closed,
    functional, switching circuits and logic gates? Did the natural source of
    energy have enough energy to power them, yet not enough to overheet them?
    And did the binary representations of instructions (the CPU instruction set)
    just arise naturally? And did the various components - like the ALU, the
    system clock, the memory, and data bus, control bus, etc. - just happen to
    form naturally and interconnect, each performing its function properly and
    working together to accomplish the whole system's united function? Where did
    the program code - which interacts with the CPU's instructions set - that
    instructs these components how to mutate and select come from?

    Do we just look at a computer and say, "well, all a computer is is a bunch of
    silicon, aluminum, phosphorus, carbon, and iron atoms that just happen to be
    in a specific arrangement - so what's the big deal? All that has to happen
    is for the proper arrangement to occur by natural means, and trillions of
    atoms are bumping together every second - surely they would eventurally hit
    upon just the right combinations". I don;t think so. We are forced to
    conclude that computers are the products of intelligent agents. And not
    because we know they are, but because we know they HAVE TO BE.

    And I personally believe the same reasoning holds up for cells. This is
    disputable because in this case, we don't know for sure that they were
    intelligently designed (we don't know their actual history) and many people
    claim that they can in fact arise purely naturally (though their concerted
    efforts have failed to even come close in over 50 years of experimentation).

    The designer is still very much in the picture, and has not (and I believe,
    will not) be made superfluous.
