I guess I missed that. This certainly seems like an accurate summary of how this discussion has proceeded:
OTOH, I don’t really see how that link you provided amounts to an admission that Behe’s calculations were based on a faulty assumption. That said, I don’t really know what Lee was trying to say there:
On reviewing “The Edge of Evolution” again, I realized I had gotten Behe’s argument wrong, he does require simultaneous mutations, since he is considering a set of two mutations, where a single mutation in the set is deleterious. Apologies, especially to rogue06.
But I do wonder in the case of chloroquine resistance, whether each of the two required mutations is deleterious by itself. I think not, since the probability of both mutations is the multiplied probability of one mutation singly.
