Phylogeny describes the relationships of an organism, such as from which organisms it is thought to have evolved, to which species it is most closely related, and so forth. Phylogenetic relationships provide information on shared ancestry but not necessarily on how organisms are similar or different.

They utilize standardized symbols to represent sex, relationships, and traits, helping geneticists analyze inheritance patterns and disease probabilities. Accuracy is vital, but errors can occur from family memories or clinical diagnoses.

Alpha diversity (or species richness), the most commonly referenced measure of species diversity, refers to the total number of species found in a particular biological community, such as a lake or a forest.

Part of this information includes relationships between organisms. While phylogeny represents the full understanding of evolutionary relationships, scientists also classify organisms into groups in order to use a common framework of language for all species known as binomial nomenclature.
