Paper Abstract: Competing theories on evolution, meaning of anthropological discoveries, regional origins, cognitive aspects. Paper Introduction: The purpose of this research is to examine human origins. The plan of the research will be to set forth the context in which the development of the species Homo sapiens can be elaborated and then to discuss theoretical and experimental work regarding such phenomena as "Lucy" and other extinct precursors of the family Hominidae, as well as theories that propose the onset of human evolution from 112,000 to 124,000 years ago. The popular culture is full of controversy regarding divisions between modern man (as denoted in the professional literature) and extinct precursor species of it. Notwithstanding the sociocultural controversy surrounding Darwin's theory of evolution, scientific investigation of the origins of human beings has evolution at its core.
