Human: Phylogeny

2.5 MYA. Discovered in 1947 by Broom and Robinson in Sterkfontein, South Africa. Broom and Robinson had made the discovery of “Mrs. Ples” (Sts 5) at the same cave site earlier that year. Because the pelvis is small, they considered it to be female. The finding of Sts 14, which also includes 15 vertebrae and 4 ribs, helped to establish the connection between hominids and the australopithecines.
