Taxa Reference is a database of phylogenetic taxonomy - how organisms are categorized based on how they evolved over time. The steps of evolution create a tree-like structure that shows how closely related organisms are, what characteristics they share, and where in history they separated. By finding a taxon on this website, you can look at its descendents and its ancestors to see how it is related to other organisms. Here is one starting point.

Information used in this website has been taken from a few different resources, cited at the bottom of each page. This website should be used as an easy-to-navigate reference tool that can link you to more in-depth resources.

Located on each taxon page is a link to "Suggest an improvement." Use this page to report errors or provide some more information to be included on the page. If you would just like to ask a question or leave a comment about the site, visit the contact page.
