This is a good, clear, compact introduction to what archeologists, anthropologists, depth psychologists and linguists have speculated upon as being the general development of primitive man,- from his beginnings as a unique member of the Primates to the end of the Stone Age. The author, a British popularizer of note, has used a common sense, non-pedantic point of view to digest technical explanations and information and tells his story, qualifying his generalizations, in a pleasing mature style. He briefly traces the creation of life to the establishment of the Primates and then discusses in more detail the emergence of Paleolithic man (600,000 years ago) and his long, slow transition from food-gather to hunter to cultivator--Neolithic man (10,000 years ago). Included in this narrative of Stone Age man's development are objective discussions of the birth of language, the growth of religious beliefs, the flowering of art, the spread of crafts, the migrations, and the gathering of populations into villages. Based on a liberal, evolutionary perspective, this is good reading for the more objective layman and inquisitive student.
