He Was a Mormon Leader and a DNA Scientist. His Own Test Broke His Faith

 What happens when modern science puts a centuries-old religious claim to the test?

In this video, we explore one of the most controversial intersections of faith, history, and genetics in modern times. For generations, members of the Church of Jesus Christ of Latter-day Saints were taught that Native Americans descended from ancient Israelites described in the Book of Mormon. It was a belief that shaped identities, inspired missionary work, and influenced church programs across the Americas. Then DNA research changed the conversation. As population genetics advanced in the 1990s and early 2000s, scientists began tracing the ancestry of Indigenous peoples through mitochondrial DNA. The findings consistently pointed toward ancient migrations from Siberia and East Asia, creating a direct challenge to long-standing interpretations of Book of Mormon history. The story became even more dramatic when some of the scientists raising these concerns were faithful members of the Church themselves. This video follows the experiences of researchers such as Simon Southerton and Thomas Murphy, examines the famous Haplogroup X debate, and looks at how Church teachings and official statements evolved in response to growing genetic evidence. But beyond the science, this is also a deeply human story about identity, belief, heritage, and what happens when evidence collides with traditions that millions have built their lives around. Watch until the end and decide for yourself: when history, faith, and DNA tell different stories, which one should people trust most?
