The Laboratory of Evolution is part of the Animal Biology Department in the Biology Institute of the School of Sciences, Universidad de la República (Montevideo, Uruguay). Since its beginning in 1992, the laboratory has worked on diverse topics of evolution and systematic of vertebrates, with emphases on mammals. Whereas our studies commonly analyze molecular data, they normally are used to understand the biology of organisms, species and phylogenetic groups

For example, we have worked on the systematic of tuco-tucos (Ctenomys) and sigmodontine rodents (Sigmodontinae), biogeography of migratory birds, population structure of the franciscana dolphin (Pontoporia blainvillei), dynamics of the Great American Biotic Interchange, phylogeography of swamp rats (Scapteromys) and the analysis of Pleistocene's refugia in Northamerica and the western Amazonia.

The research work typically includes field work, preparation voucher museum specimens, and laboratory work, typically to obtain microsatellite frequencies and DNA sequences (mitochondrial and nuclear). Subsequently, tools from population genetics and phylogenetics are used to test the hypotheses of interest.
