The largest sagittal salamander discovered during human evolution is an Ethiopian pygmy skull named KNM WT 17000. The Ethiopian Pong people are the earliest predecessors of the human race and the oldest and strongest southern ape. The sagittal salamanders of Ethiopia's neighbors seem to indicate that they are very chewing and the molars on the same skull are correspondingly large.
