Evolution is defined as “any process of progressive change”; and the theory is complex life forms from our time have descended from earlier ones that existed long ago (Hunt, p.29). The theory of evolution was first made popular by Charles Darwin an English Biologist, he spent a good amount of his time trying to find evidence to support his many ideas. It is believed that the human species has its origins in Africa. Scientists share the belief that a human like creature originated from the apes and over time, through many changes the final result was a group of hominids, they do however disagree on when and why the different characteristics begun begun to show themselves.

Life is believed to have originated billions of years ago and over time organisms mutated and evolved into other more complex life forms. It is stated that humans came from earlier primates from about 65 to 70 million years ago. Humans are the only species (as a basic biological classification containing individuasl that resemble one another and may interbreed) of Homo sapiens who are still around today; the other two Homo habilis and Homo erectus are extinct.
Below are the stages of human evolution and the order they came in.
(1) The LCA is a term used to represent our Last Common Ancestor with the apes, this group includes the Dryopithecus, they lived in Africa and were not typically a two-legged animal.
(2) The Basal Hominins are some of the earliest fossils found and are dated seven to four million years ago. This class included the Sahelonthropus and the Orrorin tugenensis, they also lived in Africa and evidence was found that they might have stood upright.
(3) Fossils dating 3.5 to 2.4 million years ago were found to be the Early Human Ancestors, they include the Australopithecus anamensin, Australopithecus Africanus, A. Garhi and Homo habilis they also lived in Africa and were discovered to have used simple stone tools. There were skeletal changes found in them which indicated that they walked on two legs.
(4) Next we have the Middle Period Human Ancestors, they lived 1.9 million to 300,000 years ago and included the Homo erectus and Homo ergaster, they made and used stone tools as well. This group left Africa for China, Georgia and Jara. They were found to have been larger, walking on two legs, and had a larger brain.
(5) The Recent human Ancestors lived from 800,000 to 250,000 years ago; this group included the Homo antecessor and Homo neanderthalensis. Fossils of Homo sapiens were also found and dated about 160,000 years ago. This group also moved out of Africa and went to the Middle East, South East Asia and Europe. They had larger brain sizes and their cultural remains were similar to preliterate living humans.
The term Human Ancestor is used to categorize all fossils dated between the split of ancestral African apes, to the earliest hominin and then to the modern humans. More up to date evidence suggests that the last common ape ancestor of the African apes and humans actually lived in Europe first and not in Africa; anthropologists found that no ape fossils existed in Africa before four million years. This means that their ancestors actually left Europe and went to Africa when the climate changes forced them to move.
What is the Concept of Culture? Name Two Theoretical Perspectives and the Proponents of those theories.
The term culture has many meanings to a lot of people, it is hard sometimes to determine what culture is there has been debates of what it really means. But culture is defined as being “the total pattern of human behavior and its products, embodied in thought, speech, action and...
