There are many types of the hominid called
Australopithecus, which means southern apes. These were small ape-like
creatures with a height between 107cm and 152cm) that showed evidence of
walking upright. It is difficult to tell whether these begins are
"humans" or "apes". Many of their characteristics are split between
humans and apes.
The many species of Australopithecus include
Australopithecus, ramidus, anamnesis, afarensis, . africanus,
acthiopicus, robustus, and boisei. The oldest known and identified
species of australopithecus that roamed the earth was a ramidus who
lived about 4.5 million years ago. Next came Anamensis, afarensis,
africanus , acthiopicus, a boisei and a robustus. Ausralopithecus boisei
roamed the earth as early as 1.1 million years ago and was on earth at
the sametime as homo habilis and homo erectus. Most of the
australopithecus fossils that have been discovered have been found in
eastern africa and have been dated between 4.5 million and 1.1 million
years old. There has also been evidence that the australopithecus "man"
lived in australia where fossils have also been found. The first
discovery of an australopithecus fossil was made in 1924.
The body of the australopithecus is
smaller than humans, but biffer than chimpanzees. Also, The brain size
of australopithecus is bigger than humans at about 475 cubic
centimeters. This is also biffer than the chipanzees, but the brains
were not developed in most areas. For example speech.
The australopithecus species all had
mostly the same features with a low forehead, a "bony ridge"over the
eyes, a flat nose and no chin. Their jaws stuck out and they had large
back teeth. Even today, many more species of australopithecus are being
discovered. Australopithecus anamensis was only named in august 1995,
even though it is one of the oldest species of australopithecus(living
between 4.2 and 3.9 million years ago.)
