Lucy was originally transported to the University of Texas because of their advancements in technology; they had the first CT scanner to have industrial uses in the world. Dr. Richard Ketchman and Dr. John Kappelman at UT used the CT Scanner to create over 35‚000 “slices” of the skeleton. While analyzing these skeleton “slices” to figure out more about the life that Lucy lived‚ they noticed a series of breaks in her right shoulder/arm
