Phylogeny refers to the evolutionary history of species. Phylogenetics is the study of phylogenies—that is, the study of the evolutionary relationships of species. Phylogenetic analysis is the means of estimating the evolutionary relationships. In molecular phylogenetic analysis, the sequence of a common gene or protein can be used to assess the evolutionary relationship of species. The evolutionary relationship obtained from phylogenetic analysis is usually depicted as branching, treelike diagram—the phylogenetic tree. Historically, the use of phylogenetic trees was restricted more or less to the study of evolutionary biology, and to disciplines like systematics and taxonomy. However, with the advent of sequencing and the widespread use of cladistics, the use of phylogenetic trees has pervaded many branches of biology and beyond. Construction of phylogenetic/evolutionary trees is now widespread in many areas of study where evolutionary divergence can be studied and demonstrated; be it pathogens, biological macromolecules, or languages.
