And of course, the whole 'locus specificity' assertion of creationists is just that - a blind assertion. Even if it is demonstrated in the primary literature, that some retroviruses may exhibit a preference for certain classes of genome sequence, when there exist tens of millions of instances of that class of genome sequence in a particular genome, then the insertion outcome is still going to be a statistically random variable. The assertion that retroviruses home in on particular loci, right down to the nearest base pair, is not only wholly untenable given the evidence from the primary literature, but would require a massive amount of magic intervention to pull off, magic intervention that is simply not evident. Indeed, I suspect that if a collection of cells in a culture were subject to retroviral infection in the laboratory, none of those cells would exhibit identical insertions.
