Mormoninfo.org, or as I affectionately refer to them, Morg, once again demonstrates they probably struggled at their logic exercises in high school. They venture into dangerous waters, where some knowledge of science would be a good thing. Sad days at the Morg.
Morg starts by assuming DNA evidence is a negative relative to Mormon truth claims. It is if you are so unschooled in biology or genetics that your idea of advanced study is a video tape from Confused Hope Ministries. But their starting point is false (big surprise). It is like thinking liberals are going to tell you about George Bush without bias. If you have half a brain, you will say "What makes you so smart?" Great question. Let's figure it out.
Morg, what did an original Israelite look like, genetically speaking? Modern Jews have almost no traceable DNA in common. We have practically no samples of any pre-Babylonian captivity Hebrew DNA, and no idea what the genetic makeup of the Lehites were. It is a false and deceptive premise to assert the tools exist to detect DNA among any of the pre-Columbian native Americans when you do not know what to look for, and how extensive the inter-marrying was for the past 2600 years.
Basically, Morg seems to think they have stumbled onto a crime-lab quality tool in the DNA evidence. Yet they are literally taking modern DNA samples without any suspect DNA to compare it too. The only crime is the assault on reason we keep seeing coming from the Morg.
