Biology

Wikipedia Reference Information

Biology

(from Greek: ???, bio, "life"; and ?????, logos, "knowledge") is the study of life. It is concerned with such topics as classifying the various forms of organisms, how species come into existence, and the interactions they have with each other and with the natural environment. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. However, together they address phenomena related to living organisms (biological phenomena) over a wide range of scales, from biophysics to ecology.

Many of the sub-disciplines of biology are ancient, such as botany, zoology, and medicine. However, biology as a unified science was first developed in the nineteenth century, as scientists discovered that all living things shared certain fundamental characteristics and were best studied as a whole. Today biology is one of the most prominent scientific fields. Over a million papers are published annually in a wide array of biology and medicine journals,[1] and biology is a standard subject of instruction at schools and universities around the world.

As such a vast field, biology is divided into a number of disciplines. The old divisions by type of organism remains with subjects such as botany encompassing the study of plants, zoology with the study of animals, and microbiology as the study of microorganisms. The field may also be divided based on the scale at which it is studied: molecular biology looks at the fundamental chemistry of life; cellular biology looks a the basic building block of all life, the cell; Physiology looks at the internal structure of organism; and ecology looks at how various organisms interrelate. Applied fields of biology such as medicine are more complex and involve many specialized sub-disciplines.
