(2) Genetic data on present human population relationships and data from the Pleistocene fossil hominid record are used to compare two contrasting models for the origin of modern humans.
(3) The present study on 47 naturally fractured enamel surfaces of premolar and molar teeth of Plio-Pleistocene East African hominids measured enamel thickness, slope of incremental lines (striae of Retzius), and the morphology of Hunter Schreger bands (HSBs).
(4) The subocclusal morphology of 168 permanent mandibular premolars (N = 77) and molars (N = 91) of Plio-Pleistocene hominids has been investigated.
(5) The morphological comparison shows strong affinities to comparative material from the Upper Pleistocene like Cro-Magnon.
(6) The cultural associations in the earlier late Pleistocene are with the Middle Stone Age.
(7) The latest fossil is the only intact skull ever found of a human ancestor that lived in the early Pleistocene, when our predecessors first walked out of Africa.
(8) The diets of these Plio-Pleistocene hominids appear to have been qualitatively dissimilar.
(9) The concentration of climate-warming carbon dioxide is now higher than at any time since the dawn of humans 2.6m years ago, an event itself marked by a new geological epoch called the Pleistocene.
(10) The morphology of the nasal bones and their articulations with the adjoining frontal and maxillary bones have recently been reported in Nature and elsewhere to be diagnostic of hominoid taxa, and cladistic analysis based on these features has been used to assign two immature Plio-Pleistocene hominoids (AL 333-105 and Taung) to different lineages (Paranthropus and Homo, respectively).
(11) Pilbeam and Gould have discussed African Plio-Pleistocene hominid evolution in the context of allometry (size-dependent morphological change).
