If I understand Simon Southerton correctly, it is possible to ascertain if any foreign intrusions at all occurred. If none are present in the time frames claimed, it does not matter what Lehite DNA is supposed to look like anyways since no new DNA appeared in the local population at the correct time.
I don't have a dog in this race in terms of the alleged historcity of the Book of Mormon. As far as I'm concerned, the most serious "problems" with the Book of Mormon have nothing to do with DNA studies and population genetics. That said, I have been somewhat of a student of the scientific theories concerning the origins of the various populations of the Americas, and it is simply a fact that (especially in the most recent studies) the science is rapidly evolving. People who have no interest in "proving" the Book of Mormon are making arguments that contact between Europe, Asia, and the Americas was much more common in pre-Columbian times than was previously believed, and they are using DNA evidence to support their theories. Your statement that "no new DNA appeared in the local population at the correct time" is just not true. In fact, just the opposite is true: they are finding that there is evidence of extensive contact between Europe and the Americas, all throughout ancient times. The old theory about the Bering Straits being the only avenue of emigration into the Americas is being shown as entirely inadequate to explain the evidence. The Raghavan study published in Nature in November of last year is just the most recent study to underscore the increasing amount of evidence that the DNA picture of ancient America is not nearly as simple as most of the non-Mormon/ex-Mormon arguments would have one believe.
Bottom line: I think "President Newsroom's" latest entry in this essay series is actually quite balanced, and, on balance, very accurate in its claims that DNA studies don't have the ability to say much, if anything, about the historicity of the Book of Mormon.
