    But if the pathway is selected, then that makes Behe's calculation a lower bound, since he is interested in non-selectable mutations.

    We don't know if other pathways are possible, or even that they've evolved and we've not detected them. We also don't know how often this particular pathway might have evolved independently.
    There is uncertainty involved, yet we have enough information to make some conclusions, based on examining two instances (HIV and malaria) to see what evolution can actually do.

    What about HIV indicates it should be under selection to evolve new protein-protein interactions? It's a highly successful virus that seems to be doing just fine as it is.
    Why should anything evolve, then? But HIV could for instance become more of a benign parasite and less of a disease, for instance.

    In contest, the evolution of HIV from SIV opened up an enormous new reservoir of potential hosts. If you want to look at interesting evolutionary events, you look there.
    You just answered your own question?

    Behe hasn't. What does that tell us?
    Behe has looked for new function, though, and based his estimates on what he sees.

    No, he doesn't look at the malarial parasite. He looks at a single gene where mutations enable drug resistance. That's it.
    He looks at other medications that required a single mutation to confer resistance, and finds that these instances occur at the rate expected, about the square root of the two-mutation chloroquine resistance.

    I have no idea what "double-CCC" means. it's not a scientific terms, so you probably need to define it.
    two required non-selectable mutations Behe calls a Chloroquine Complexity Cluster (or CCC), because the development of resistance to chloroquine in the malaria parasite required two simultaneous mutations. The development of resistance happened, but it required a tremendous number of parasites to find it. So a "double CCC" Behe concludes, is outside the range of evolution.

    Then why haven't they done so? And how would they identify them?
    That would be four non-selectable mutations or more.

      Well, again, independent events have the same probability regardless of the timing of those events. So it's convenient to speak of simultaneous mutations, because that indicates that the mutations have to all be simultaneously present. But no one is thinking all the mutations have to occur at exactly the same moment in time.

        https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2954758/

        There might be a fourth, per CDC documents. Obviously, that says something about the probability of these mutations arising that, from what i've seen of Behe's arguments, isn't considered by him.
        Yet we read:

        CCCs do happen, if the population numbers supply them. In recent years chloroquine resistance has popped up a number of times independently.

          In rereading Edge of Evolution, I discovered I misrepresented Behe's edge:

          Source: Edge of Evolution

          Still, I think it’s better to err on the side of caution, allow room for the odd exception like sickle hemoglobin, and draw the line at complexes of three kinds of proteins (that is, two binding sites), as I do in Figure 7.4.

          © Copyright Original Source


          So the edge is at two new binding sites (or as mentioned previously, a double-CCC), not just one.

            The Edge of Evolution: The Search for the Limits of Darwinism by Michael J. Behe is not reputable scientific reference. First and foremost unethical statistics.

            The Lurch has documented this.

              Ok, you're misrepresenting and misunderstanding things in such a scattershot manner that it's getting hard to understand what's going on. I'm going to try to focus back on the central things:

              There's no such thing as a "non-selectable mutation". Any mutation that happens has the potential to be selected in the right context. Since you've defined an intelligently designed sequence through a nonsense term, it's not possible to work with that.

              So again, give me a rigorous definition of something that can be searched for in a collection of genomes using an algorithm that would be evidence of ID. Not just some waffly term that doesn't make sense, like non-selectable mutation. Something that you can use to design an algorithm to search for it.

              Again, false. It does not require simultaneous mutations. If you keep saying things that are clearly false, i'm going to ask you to leave this thread.

                Well, "non-selectable in the current context" would be implied.

                Again, false. It does not require simultaneous mutations. If you keep saying things that are clearly false, i'm going to ask you to leave this thread.
                That is, two mutations that are required to be simultaneously present.
