The Platymeric Index is a measure of the curvature of the femur, and a Platymeric Index of 70 indicates a relatively straight femur. The negative value from the Platymeric Index discriminant function suggests an ancestral group that is not of European descent. Native American populations tend to have relatively straight femurs, so the most likely ancestral group for this individual is Native American.
