The science that concerns itself with these objects we will indicate by the name biology or the doctrine of life. The term came into its modern usage with the six-volume treatise Biologie, oder Philosophie der lebenden Natur (1802–22) by Gottfried Reinhold Treviranus, who announced: The objects of our research will be the different forms and manifestations of life, the conditions and laws under which these phenomena occur, and the causes through which they have been affected. Karl Friedrich Burdach used the term in 1800 in a more restricted sense of the study of human beings from a morphological, physiological and psychological perspective ( Propädeutik zum Studien der gesammten Heilkunst). In 1797, Theodor Georg August Roose used the term in the preface of a book, Grundzüge der Lehre van der Lebenskraft. The first German use, Biologie, was in a 1771 translation of Linnaeus' work. It was used again in 1766 in a work entitled Philosophiae naturalis sive physicae: tomus III, continens geologian, biologian, phytologian generalis, by Michael Christoph Hanov, a disciple of Christian Wolff. The Latin-language form of the term first appeared in 1736 when Swedish scientist Carl Linnaeus ( Carl von Linné) used biologi in his Bibliotheca Botanica. Historically there was another term for biology in English, lifelore it is rarely used today. The first to borrow it was the English and French ( biologie). Despite this, the term βιολογία as a whole didn't exist in Ancient Greek. Those combined make the Greek word βιολογία romanized biología meaning 'biology'.
Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the world around them. Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. From the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.
īiologists are able to study life at multiple levels of organization. Finally, all organisms are able to regulate their own internal environments. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Another major theme is evolution, which explains the unity and diversity of life. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.
