Introduction This paper will explore the theory of evolution and its main contributing species. The Australopithecus is the most primitive common ancestor between humans and apes. Though its contributions to evolution were few, it was still a vital part in evolution being the first ape-like creatures to be known as related to modern humans. Homo sapiens are the first species that share a genus with modern humans. They are slightly more advanced than Australopithecines. Homo erectus are one of the better known of the genus Homo. Finally, Homo neanderthalensis, our closest relatives. The fossils found, the structure and the disappearance of these species will be discussed in further detail throughout this paper.

Australopithecus Australopithecines were hominids (Johanson & Edey, 1981) that lived between 2.95 and 3.85 million years ago. (Smithsonian Museum, 2016) First discovered by Raymond Dart, he decided to name the species, Australopithecus africanus, meaning southern (Australo) ape (pithecus) from Africa. (Johanson & Edey, 1981) The fossil he found was from a lime quarry in Taung, South Africa. It was of a six-year-old with a full set of baby teeth. (Johanson & Edey, 1981) Apes were not found in South Africa yet baboons were. Dart knew it was definitely not a baboon and was fairly certain it was not a chimpanzee due to the high-crowned cranium. (Johanson & Edey, 1981) Also, both baboons and chimpanzees have large canine teeth while the teeth of this fossil were…
