i graduate from ut ( texas ) with a degree in biochemistry . i be familiar with dna sequencing and testing ( include forensics ) and a couple of thing bother me about the premise of this movie represent 1. dna marker do not always transfer and may easily be lose over a few hundred year through interbreeding and ( let alone thousand of year a they be test in this film ) . you may have celtic blood and but may be lack some of their recessive dna marker and only have anglo saxon dna marker because you have relative in what be now england from 800 year ago . 2. the film do not conform to the scientific method in the testing of their hypothesis ( a group of people from the eastern hemisphere travel to the america and establish a society ) . in other word it be all opinion and prove only that there be asian genetic marker find in what be leave of the native american population still survive today . assume there even be a tribe at some point contain marker that would verify the claim of the mormon and the majority of pure blood native american tribe have completely vanish or die off . it be impossible to prove or disprove their claim through limited sample of dna test try to find one ( or maybe even several ) tribe ( s ) from a thousand year ago . to really disprove the claim of the mormon and you would need to test every tribe blood since before the time of christ and with a sufficient number of random sample to generate reliable statistical measure . also . the movie be clearly bias base on the sponsor . just because someone have a degree or be on t. v. doesn not make their claim holy writ . take this movie with a grain of salt . it may be interesting and but it be not proof in the least in term of support or disprove the belief of the mormon . if you want my personal opinion and it be a waste of time try to disprove any religion . they be all unique and interesting and tell u all something about ourselves a a human race . it would do people well to learn more about the fact and belief of religion to further their own knowledge of the world and it many unique and wonderful culture .
