WebBiology is the scientific study of life. [1] [2] [3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [1] [2] [3] For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. An advantage of the biological species concept is that it incorporates, in its classification of taxa, assessments of gene flow and reproductive isolation.
