As fascinating as it is for man to contemplate his future it is as fascinating for him to delve into his origins. The scientific means at his service belong to the fields of archaeology, paleontology, and anthropology. In this concise text the result of explorations in these fields as well as the accidental findings which contribute to our picture of man's development are clearly and dramatically stated. The various ages of man are considered, man's relationship to apes, the manlike apes, the apelike men, and finally the first recognizable modern man are reviewed in sections which illustrate the specific techniques used by science in identifying their evidence. Despite the many texts dealing with prehistory, this text, combining much meticulous factual information with a stimulating style, is recommended for supplementary school reading and for any high school reader with a normal curiosity regarding his heritage.
