Study of Life

Biology examines the structure, function, growth, origin, evolution, and distribution of living things. Using tools like genetics, biologist try to classify and describe each organism, their functions, where the species evolved from, and how it participates in its environment.

Biology is a large field encompassing specialized disciplinces such as botany, zoology, microbiology, molecular biology, and ecology. Each discipline tackles a different aspect of life, with the same overall goals.

One of the central concepts in biology is that life is dynamic, that it develops though a process called evolution, and that all lifeforms have a common origin. Each species has come about through selective forces involving breeding, competition, available foods, and genetic recombination.
