Sociology is a relatively new academic discipline among other social sciences including economics, political science, anthropology, history, and psychology. The ideas behind it, however, have a long history and can trace their origins to a mixture of common human knowledge and philosophy.
In the early 20th century, sociologists and psychologists who conducted research in industrial societies contributed to the development of anthropology. It should be noted, however, that anthropologists also conducted research in industrial societies. Today sociology and anthropology are better contrasted according to different theoretical concerns and methods rather than objects of study.
Sociobiology is a relatively new field to branch from both the sociology and biology disciplines. Although the field once rapidly gained acceptance, it has remained highly controversial as it attempts to find ways in which social behavior and structures can be explained by evolutionary and biological processes. Sociobiologists are often criticized by sociologists for depending too greatly on the effects of genes in defining behavior. Sociobiologists often respond, however, by citing a complex relationship between nature and nurture. In this regard, sociobiology is closely related to anthropology, zoology, and evolutionary psychology. Nonetheless, for most in the discipline, its ideas are unacceptable. Some sociobiologists, such as Richard Machalek, call for the field of sociology to encompass the study of non-human societies along with human beings.
Sociology has some links with social psychology, but the former is more interested in social structures and the latter in social behaviors. A distinction should be made between these and forensic studies within these disciplines, particularly where anatomy is involved. These latter studies might be better named as Forensic psychology. As shown by the work of Marx and others, economics has influenced sociological theories.
