any evidence to support this theory‚ or is it a mere speculation with lack of scientific and ontological evidence. This essay will look at some prominent archaeological evidence‚ like Lucy fossils‚ and some ontological implications. One of the most prominent fossils is the skeleton of Lucy‚ she “is an Australopithecus apheresis‚ a well-documented group of early hominines” (Kappelman). She was found in Africa by Donald Johanson and Tom Gray. A hominine is a classification of species which are related

Introduction The most well-known‚ universally dispersed of the early African hominins are the australopiths. This effective group of hominins is integrated of a genus known as Australopithecus. These hominins go as far back as three million years allowing them to be hominins that had lived the longest period of time and were reported on. The hominins have been located in areas of Africa and have been found to be bipedal (walk upright)‚ have small-sized brains‚ and have exceptionally big teeth

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

composite of bone fragments from different individuals of this species. The lighter portions represent bone fragments‚ and the missing pieces are filled in to reveal what an entire skull probably looked like. One of the most complete specimens of A. afarensis found so far was announced in 2006. A team led by Ethiopian scientist Zeresenay Alemseged unearthed the partial skeleton of a three-year-old female at Dikika in the Afar region of Ethiopia. Nicknamed “Selam‚” the Dikika child dates from around 3

a human. Close to the skeleton‚ they found footprints that were in the shape of a human foot. Dr. Johanson called this Australopithecus afarensis. Peter Schmid‚ paleontologist at the Anthropological Institute in Zurich studied Lucy for a long while and here is what he said: “When I started to put the skeleton together‚ I expected it to look human. Everyone had talked about Lucy as being very modern‚ very human‚ so I was surprised by what I saw. I noticed that the ribs were more round in cross-section

they can climb on trees and move from one place to another. But with the decrease in number of trees‚ requirement for bipedalism increased. In an article by Wayman E.

Her pelvis was broad and she has thigh bones which were

These distinctions will be investigated and specific reasoning behind their formation will be analyzed. I will also compare early hominids to modern Homo sapiens and explain particular factors that lead to their evolutionary changes. The Australopithecus afarensis‚ one of the earlier hominids‚ has a brain size of 500cc centimeters as compared to modern Homo sapiens who possess a brain size of more than 1350cc. The adaptation of bipedalism is also an important highlight of human evolution and there
