THE STAGES OF HUMAN EVOLUTION
Prosimians 65 million years ago Monkeys 40 million years ago
Prehistoric apes 30-20 million years ago Modern apes 17-4 million years ago
Ramapithecus: (pithecus = ape) This creature lived about 14 - 8 M.Y.A. (Million Years Ago)
... the most ancient human ancestor
...a small ape-like creature (14 kg) which probably walked upright.
Australopithecus ramidus: (austral = southern; ramidus = root) 4.4 M.Y.A.
... some teeth were human-like
... molars were like those of a chimpanzee
... ca. 1.2 meters tall.
... foramen magnum suggests upright walking
... arm bone structure was different from that of apes.
Australopithecus afarensis: (Afar = a region in Africa)
...4 - 2.8 M.Y.A.
..."Lucy", 3.5 million years old found by Don Johanson in 1974 in Hadar,
Ethiopia. 40% of her skeleton was found. Laetoli footprints (3.8 M.Y.A)
in Tanzania, found by Mary Leakey, are the oldest evidence of bipedalism.
...possessed a small skull, ape-like features, low forehead, flat nose, no chin
but jutting jaws with massive teeth.
...brain was one third that of modern humans (1350 mm)
... was 1.1 m tall and weighed 30 kg. She was no bigger than a six-year-old
child.
... had great muscular strength ... lacked the power of speech.
... walked slightly bow-legged. Its chimpanzee-like hips and curved toes
and finger bones suggest it spent much time in the trees.
... family groups would have foraged for plant foods including tough, hard,
or fibrous fruits and seeds. Individuals might have used crude tools of wood
and stone to scavenge meat from carnevors' kills. ... no evidence that tools
were made.
Australopithecus africanus: (africanus = African) 3 - 2 M.Y.A.
... most famous fossil is Taung Child (2 - 1 M.Y.A.). Found by Raymond
Dart in 1924.
...close in size to an ape (12-year-old) ... brain smaller than that of Homo
erectus.
... upright with large teeth shaped like those of a human
... average age of death was 22 years.
Australopithecus robustus: (robustus = strong) (2 - 1.5 M.Y.A.)
...1.6 m tall, 50 kg. ...the ultimate chewing machine
... average age of death was 17 years.
Australopithecus boisei: (1.8 M.Y.A.)
... nut cracker human, a more massive version of A. robustus from which
it may have evolved.
...the height of a modern man but with a structure resembling the gorilla.
Homo habilis: (homo = human; habilis = able) 2 - 1.5 M.Y.A.
...Handy human; evidence of the manufacture of stone tools
...face still primitive.
...brain one half the size of a modern human.
...more sophisticated with rudimentary speech... may have built first shelters
Homo erectus: (1.6 million to 200 000 years ago.)
... upright human; protruding jaw, no chin, thick brow ridges and a long
skull
...teeth smaller than in habilis
...much larger brain than habilis (1000 mm)
...may have had advanced speech ... controlled fire
...made more sophisticated tools then predecessors.
... left Africa and spread throughout Asia and Europe
Homo sapiens: (sapiens = thinking, 400 000 to 40 000 years ago, Southern Africa)
...human the wise or thinking
...appearance very similar to a modern human
...high forehead encasing a large brain, lower jaw with chin
...evidence of spiritual development (burials in Shanidar cave, north Iraq)
...the earliest Homo sapiens were Neanderthals
Homo sapiens sapiens (... 40 000 to present)
...human the very wise (wise, wise or thinking, thinking)
...excellent hunter, sophisticated weapons, control over environment
...spread to North America and Australia
...first to develop art (Cave paintings and Venus figures)
...earliest Homo sapiens sapiens were Cromagnons.
