An Introduction to Social Biology examines the application of biological principles in order to live a satisfactorily life. This book contains 14 chapters that discuss certain aspects of politics, theology, morality, and philosophy. The first chapters address the properties of living things and some paleontological evidence of evolution. Other chapters deal with the relationship between man and evolution; behavior of man as an animal; process of human and animal reproduction; definition of the theory of inheritance; relationship between agglutinins and agglutinogens; effects of mixing a donor’s blood and the receiver’s serum; and development of a fetus. These topics are followed by discussion of the social hygiene and the history and developments in medicine. An analysis of the diagnostic devices and techniques employed in the middle age is provided. The last chapters explore the quality and characteristics of food and beverages, as well as the social life among animals. The book can provide useful information to the biologists, students, and researchers.
