William Howells, noted anthropologist at Harvard and author of the immensely popular evolutionary story of man (Mankind So Far) published in 1944, has written his current book with ""the same subject and similar plan""; however, in the light of the many facts and findings that have been uncovered in this field in the intervening years, Mankind In the Making must be considered a new, rather than a revised, study. Howells interprets the vast body of extant facts on the basis of the evolutionary theory (the combination of heredity and natural selection), tracing that process as it applies to vertebrates, mammals, primates, and -- most comprehensively -- through the migrations and changes in the races of modern man. 193 line drawings by the Swedish artist Janis Cirulis and 8 pages of photographs of racial types render the text more easily understandable for amateur anthropologists, zoologists, and biologists. Appended to the text are index, glossary, and ""a formal classification of those main groups of vertebrates and primates which are important to man and his ancestry"". Too specialized for most general readers, this is an up-to-the-minute reference work in the field of the evolution of the races of man.
