In attempting to compare the lost bones with Earhart’s bones, Jantz co-developed a computer program that estimated sex and ancestry using skeletal measurements. The program, Fordisc, is commonly used by forensic anthropologists across the globe.
Jantz compared the lengths of the bones to Earhart’s measurements, using her height, weight, body build, limb lengths and proportions, based on photographs and information found on her pilot’s and driver’s licenses. His findings revealed that Earhart’s bones were “more similar to the Nikumaroro bones than 99 [percent] of individuals in a large reference sample.”
“In the case of the Nikumaroro bones, the only documented person to whom they may belong is Amelia Earhart,” Jantz wrote in the study.
