Definition for Biology
From Biology Forums Dictionary
Biology is the natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. The term biology in its modern sense appears to have been introduced independently by Karl Friedrich Burdach (1800), Gottfried Reinhold Treviranus (1802), and Jean-Baptiste Lamarck (1802).
Biology is a vast subject containing many subdivisions, related subjects, and principia thereof. Five unifying principles form the fundamental axioms of modern biology: cell theory, evolution, gene theory, energy, and homeostasis.
These fields are further divided based on the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and ecology examines how various organisms interrelate with their environment.
