The application of phylogenetic and genomic analyses to the study of animal biodiversity and evolution, with a specific focus on mammals, is the main goal of the Phylogeny and Phylogeography of Mammals lab. Using next-generation sequencing techniques and advanced bioinformatics tools, the population divergence and speciation process in different species complexes are analysed in order to obtain a better description of our biological diversity. These modern methodologies are also used to study kinship relationships and connectivity between populations in some species of great conservation importance, such as the Pyrenean desman.
