It is irritating when someone claims that no one knows what Lehi's DNA would look like. It would be Near Eastern.
Why don't Mormons address the studies that focus on the spread of agriculture from the Near East into Europe? Those studies use DNA markers to identify Near Eastern people. It stands to reason that similar markers should be found in the Americas if the Book of Mormon were true.
Here are some studies:

Finally, about the idea that all of America's indigenous people are related to Book of Mormon people. This assumes that Near Eastern DNA markers have been diluted into a pool of people descended from paleo-Indians. Now seriously consider what that implies. It means that Book of Mormon people from Adam and Eve came from the cradle of civilization into America and mixed with a population of people that were not from Adam and Eve. The pre-Adamite (co-Adamite) theory is a fundamental source of racism. How did that get approved without revelation?
