DNA and genomic sequencing is by far the most Chapter | 1 Tetrapod Relationships and Evolutionary Systematics popular approach today because it provides so much information regarding history. Each gene can produce anywhere from 100 to 10,000 characters. In addition, the summary of all genes in a coalescent framework provides the history of relationships of populations or species. Systematic study involves the comparison of two or more samples of organisms through their characters. This comparison involves two procedural concepts: the OTU, operational taxonomic unit; and character states.

Chapter | 1 Tetrapod Relationships and Evolutionary Systematics an interpretation of the Code and selects or rejects the decision, thereby establishing a precedent for similar cases in the future. All animals extant or extinct are classified identically, using the same rules, classificatory hierarchies, and names where applicable. This practice avoids dual and conflicting terminology for living species that may have a fossil record. Further, extant and fossil taxa share evolutionary histories and are properly classified together.
