UNIT 3 OUTLINES
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.
