Hominid Evolution Essay
Introduction to Hominid Evolution
Hominid evolution is the theory of the origins of the human species (Homo sapiens).
Current understanding of human origins is obtained largely from the findings of paleontology,
anthropology, and genetics. Of all primates, humans share particularly close affinity to other
members of a group known as hominoids, or apes. Humans and their immediate ancestors,
known as hominids, are notable among hominoids for their bipedal locomotion (Using two legs
for walking), slow rate of maturation, large brain size, and, at least among the more recent
hominids, the development of a relatively sophisticated capacity for language, tool use, and

The Australopithecus garhi fossils are distinctive from
those of Australopithecus afarensis and Australopithecus africanus, although the skull cranial
capacity is similar. The premolars and the molars are larger than other australopithecine, similar
to Paranthropus boisei. Few primitive shaped stone tool artifacts closely resembling Oldwan
technology were discovered with the Australopithecus garhi fossils, dating back roughly 2.6 and
Australopithecus boisei/Paranthropus Boisei
The relatively small brain size of 550 cm3 is similar to that of Australopithecus afarensis and
Australopithecus africanus. Males were larger than females, as with all australopithecine species,
standing 1.37 and 1.24 meters tall respectively. The skull was designed for heavy chewing of
ground tubers, nuts and seeds. Paranthropus boisei inhabited savannah and woodland
environments. The cranium of Paranthropus boisei was first discovered in Tanzania in 1959. The
fossil was dated to 1.75 million years old. 11
In its appearance, Homo habilis is the least similar to modern humans of all species in the genus.
Homo habilis was short and had disproportionately long arms compared with modern
