Overview

Provisional Australopithecines

Gracile Australopithecines

Robust Australopithecines



OVERVIEW
 

    1.    Extinct subfamily of hominids.
 
    2.    Lived during Pliocene and Pleistocene Epochs (5 mya to 1 mya).
 
    3.    Two genera have been identified:  Australopithecus and Paranthropus. A third possible genus is Ardipithecus.
 
    4.    At least 9 species have been identified.
 
    5.    Divided into three groups: provisional, gracile, and robust.
 
    6.    Debate over whether or not they belong in the family Hominidae.
 
    7.    Distribution is confined to Africa.
 
    8.    Climate in east Africa involved cooling trend, decrease in forest areas, increase in savanna grasslands, semiarid to semihumid conditions. Climate in southern Africa was dry with savanna grasslands for all of Cenozoic Era.
 
    9.    Most fossils found near present or past water sources, especially rivers and lakes, or in cave deposits.
 
    10.    Bipedalism developed before significant changes in skull. Humans evolved "from the ground up." Dental traits become modern looking before brain (especially size) does.
 
    11.    Transitional characteristics between humans and other apes:  arm:leg ratio, divergent big toe, brain size, shape of brain case, prognathism, some dental characteristics.
     
     
    12.    Little to no evidence of cultural remains.
