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.
Marine Biology
Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
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.
Jane Roberts in The God of Jane: A Psychic Manifesto, p. 17
Biology
No biologist today would think of submitting a paper entitled "New evidence for evolution;" it simply has not been an issue for a century.
Douglas J. Futuyma, Evolutionary Biology, 2nd ed., 1986, Sinauer Associates, p. 15
