{{further|Computational phylogenetics}}

[[Evolutionary biology]] is the study of the origin and descent of [[species]], as well as their change over time. [[Informatics]] has assisted evolutionary biologists by enabling researchers to:
* trace the evolution of a large number of organisms by measuring changes in their [[DNA]], rather than through physical taxonomy or physiological observations alone,
* compare entire [[genomes]], which permits the study of more complex evolutionary events, such as [[gene duplication]], [[horizontal gene transfer]], and the prediction of factors important in bacterial [[speciation]],
* build complex computational [[population genetics]] models to predict the outcome of the system over time<ref>{{cite journal | vauthors = Carvajal-Rodríguez A | title = Simulation of genes and genomes forward in time | journal = Current Genomics | volume = 11 | issue = 1 | pages = 58–61 | date = March 2010 | pmid = 20808525 | pmc = 2851118 | doi = 10.2174/138920210790218007 }}</ref>
