Biology is a common science that includes an aggregation with existing organisms, including their physical, chemical structures, function, development and evolution. In general, 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.Biology developed quickly with Anton van Leeuwenhoek's dramatic improvement of the microscope. A central organizing concept in biology is that life changes and develops through evolution, and that all life-forms known have a common origin. Genes are the primary units of inheritance in all living organisms. A gene is a basic unit of heredity and corresponds to a region of DNA that influences the form or function of an organism in specific ways.
