A 9,000-year-old spear point was found near Salt Lake City, Utah. An amateur anthropologist solves the puzzle of the hunter's origin. As it turns out the mostly Celtic author and the hunter share a 40,000-year-old gene mutation from central Asia. They also have in common blood type O, the author by happenstance and the Native American because blood type A and B are almost entirely absent, as is true in their homeland, north eastern Siberia.
