Ardi moved in the trees using a grasping big toe, yet her pelvis was shorter and broader than an ape's—indicating that she could walk bipedally. Ardi is proudly displayed on the front cover of Science journal and school textbooks as if paleo experts are certain she holds a place in the evasive ape-to-human progression. Soon after, White's team found more fossil bones, from the hominid's hand, skull, pelvis, feet, and on and on--110 pieces all told.
