The book "Fertility of the Unworthy" by the famous author U. A. Chapple is a leading work in the study of the evolutionary approach to the issues of realizing human fertility. In this book, the author expresses his own innovative views on what aspects influence reproductive success and heredity in different sociocultural and natural environments. Chapple examines in detail the concept of "unworthy" in the context of evolutionary biology and argues what factors affect the fertility of people who can be recognized as such. Fertility of the Unworthy contains a significant amount of scientific information, but is presented in an accessible form for a wide range of readers interested in questions of evolution and fertility.
