LDS Church and DNA research

Last night, my brother-in-law DE asked me about DNA research and whether it supports - or undermines - the truthfulness of the Book of Mormon. I've never looked into the topic so I didn't have an opinion on it. As a follow-up, DE sent me two articles - one article from the USA Today and one article from the LA Times. Both of the articles are a couple of years old and were prompted by a book that was being published at the time. I just read both articles and they are interesting. It would appear that some members - particularly those in Central and South America and the South Pacific - find this research problematic to their faith since it contradicts what they have been taught in the past. For me, I have to admit that scientific evidence is not central to my faith so I'm not terribly concerned about these findings. It doesn't affect my belief in the Book of Mormon or any other part of the Church. I assume there is some perfectly reasonable answer to all of this and that we'll know it in the fullness of time. In the meantime, we should acknowledge this is an area that isn't clear-cut, one way or the other, and be willing to live with some ambiguity. Obviously, that's easier for some people than others. As in everything else, God has a perfect knowledge of all things (including the exact ancestry and progeny of people in the Book of Mormon, the other inhabitants of those geographic areas, etc). So, if we want to know answers to questions such as "should I continue to be a member of this Church in the face of these studies" or "is the Book of Mormon true", we can ask God in prayer and he will testify to the truth via the Holy Ghost. That is a blessing that we all have in our lives and one that I would encourage people to utilize more often.
