Biology
Biology is the natural science that involves the study of life and living organisms, including their physical structure, chemical composition, function, development and evolution. Modern biology is a vast field, composed of many branches. Despite the broad scope and the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation of new species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. See glossary of biology.

Despite the beliefs and teachings of religion and psychology, impulses are biological and psychic directional signals to nudge the individual toward his or her greatest opportunities for expression and development privately, and also to insure the person's contribution to mass social reality.

No biologist today would think of submitting a paper entitled "New evidence for evolution;" it simply has not been an issue for a century.
