By: Janard Megonnell Common name: unknown Features: • Premolar and molar morphology point to niche affinities with ancestors • Strong crown asymmetries, in particular enlarged buccal cusps, characterize the upper and lower premolars • an ape-like molar shape prevails Region: • Ethiopian river valley Common Native name: unknown to: • Kenya • Ethiopia Features: • large canines parallel (rather than parabolic) toothrows • asymmetrical premolars and molars • Mandibular remains display a robust bony shelf posterior to the incisors • infero-posteriorly sloping mandibular symphysis • Common name: unknown Region: • Northern Africa • Western Asia Features: Parallel postcanine tooth rows. Amarked angle of the mandibular condyles long axis, reflecting the angle of the mandibular fossa on the cranial base. A canine-premolar diastema. Large canines and incisors. Molars with ascending size order (i.e., the smallest first). A triangular third molar crown shape. Serrated molar roots. Common name: None Features: • There is a forward projecting anterior superior iliac spine. • A very small articular surface for the sacrum. • A marked outward flare of the iliac blades. Transportation: • Isolated to Africa • Hunter gatherers followed food supply Common Name: Not established Features: • The lower face is prognathic with procumbent incisors. • Canine roots are placed quite laterally to the nasal aperture margin. • The premaxillary surface is separated from the nasal floor by a blunt ridge and is transversely and sagittally convex. • The palate is vertically thin. • The zygomatic roots originate above P4/M1. • dental arcade is U-shaped, slightly divergent dental rows. Transportation: • Sedentary in Ethiopia Common Name: Handy Man Features: • large scimitar-toothed predatory cat the size of a jaguar • H. habilis used tools primarily for scavenging, such as cleaving meat off carrion, rather than defense or hunting • Homo habilis is thought to be the ancestor of the lankier and more sophisticated Homo ergaster • Human appearance Tranportation: • Sedentary lifestyle in Africa • Along side Australopithecus Common name: unknown Features: • More anterior foramen magnum position. • Deeper mandibular fossa with well-delineated, projecting, articular eminence. • Nearly horizontal orientation of nuchal plane. • Expanded height of occipital plane of the occiput, with a concomitant low inion position. • Decreased facial prognathism, especially subnasal. Region: • South Africa Common name: Not established Features: • lack of crests and heavy muscle markings that characterize australopithecine crania. • A marked constriction of the braincase behind the orbitals • A bulging frontal bone that rises steeply to meet the square parietal bone • An occipital bone that is smoothly rounded rather than flexed as in Homo erectus. Transportation: • Northern Kenya • Isolated in Africa Features • Increased cranial breadth across the parietal bones. • Increased occipital bone length. • Broader nasal bones. • Broader nasal opening. • Shorter cranial base. • Greater development of the mandibular symphysis. Common name: Working man Transportation: • Sedentary to South and Easter Africa Common name: upright man Features: • frontal bone is less sloped • dental arcade smaller than the australopithecines • the face is more orthognatic (less protrusive) • • large brow-ridges and less prominent zygomata (cheekbones) hominins stood about 1.79 m (5 ft 10 in) Transportation • Migration from Africa to Asia Common name: Human being Features: • A broad, low frontal that is evenly curved. • Presence of a wide sagittal keel. • Supraorbitals that are a thickening at the forward edge of the sloping frontal. • A shallow sulcus above the supraorbitals. • A short face that is very broad. • Expanded maxillary sinuses and consequentially puffy zygomatics. • The orbits are spaced far apart. • The nasal bones are broad and have little angulation. • The dentition was moderate in size. Transportation • Hunter-Gatherers that followed food
