On December 6, Little Foot, the most complete skeleton of a human ancestor ever found, made its debut at the Hominin Vault at University of Witwatersrand's Evolutionary Studies Institute in Johannesburg, South Africa. The ancient fossil’s public unveiling ends a painstaking journey of discovery and assembling that began in 1994, when paleoanthropologist Ron Clarke stumbled upon fragments of four left foot bones while rummaging through a museum box.
