Kevin Jones and Derinna Koop, both archaeologist with the state of Utah, say the shape of the incisors suggest the skeleton is more likely Native American.
About 90 percent of Native Americans (and Asians) have distinctive enamel ridges on the back of their incisors, which give them a peculiar shovel shape. Only 8 percent of Caucasians have these extra ridges.
Also, Everett had fillings in two of his molars, and the skeleton's teeth don't show any dental work.
Granted, Jones and Koop have only seen photos so far. Only 60 percent of the teeth were found, and Everett's dental records are not completely clear.
The University of Colorado scientists who analyzed the remains still say the DNA evidence is "incontrovertible": a 25% genetic match with Ruess's nieces and nephews, exactly what it would be for an uncle.
Ruess' family say they will have the remains independently retested.
