Since you don't really think that much of the DNA argument anyway, why even bother reinterpreting his words? Why not simply argue that the Native Americans are Lamanites? I mean, DNA has no light to shed on the issue, from your perspective, right? No?
Are you asking if I think DNA is useless in general or just in this instance?
I learned in my psych studies about reliability and validity. A test must be reliable. It must measure the same every time. Take a measuring tape and measure how tall a person it over and over and the results should be the same each time. If sometimes the measurement said 5' 9" and sometimes 6' the tape would not be reliable. If the tape measure 5'10 1/4" repeatedly, then it is reliable.
But there is also validity. It doesn't do any good for a test to be reliable if you think you are testing for something the test doesn't do. For instance, I could take those very reliable tape measurements and say that I had determined since the measurement was reliable that I had measured the person's IQ at 110. This means the measuring tape used for IQ is not valid.
DNA does great things. I love all the CSI shows. But you can't use DNA to determine every single person on any one genetic tree.
Do you think it strange that there have been no discoveris of haplogroup I among Native Americans? We know that Scandanvian explorers were in the Americas frequently, and at least once for an extended period of time. Since it the nature of men to spread their DNA wherever they go, why do we not see any haplogroup I?
Oh, yes, looking through some of the major publications on DNA and the American Indian, I found a very surprising statistics. The study by Karafet et al used a sample of 19 individuals to make their determination. Wow. 19 Indians.
So, no, I don't see DNA as a valid test of global migrations, small immigrant populations, and certainly not as having anything pertinent to say about the Book of Mormon.
