Hominid evolution: a tale of two trees Dental morphological traits that are of interest in human populations today can be seen in the fossil record beginning with the Australopithecines between 4 and 1 million years ago (Schroer and Wood, 2013), and some traits occur even earlier in primate evolution, such as the Y-5 pattern during the Miocene (Pilbeam et al., 1977). Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.3 to 1.34 or 1 million years ago. Homo erectus, extinct species of the human genus (Homo), maybe an ancestor of modern humans (H. sapiens). Three cranial traits used to differentiate gracile and robust Australopithecines include the robust Australopithecine having a sagittal crest, a more robust mandible, and a flatter face, where the gracile has no sagittal crest, a less robust mandible, and more visible prognathism.
