EVOLUTIONARY GENETICS

Group description/Main objectives

The general goals of the group are to understand the evolutionary mechanisms that shape the genetic diversity and demography of natural and domestic populations, investigate the role of hybridization particularly in the evolution of homoploid and polyploid fish species and its relevance for speciation, and to search for the mechanisms involved in molecular evolution and/or environmental adaptation and stress. To address these goals, we use cutting-edge approaches (genomics, transcriptomics and epigenomics) and data analysis methodologies. Moreover, the data assembled by the group represent an invaluable tool for the conservation genetics of several Iberian vertebrates, many of which are currently threatened. Identically, molecular data and pedigree analysis are used to characterize, define and carry out proper conservation programs of domestic Animal Genetic Resources (AnGR).

Present research topics are divided into four main thematic lines, which are targeted towards specific animal models (both from natural and domestic populations): 1) Evolutionary history and speciation in natural populations (dolphins, Eurasian mustelids and genets, Procellariiform seabirds, fire salamanders and endemic freshwater fish); 2) Hybridization in evolution and speciation (dolphins, homoploid and polyploid fish complexes); 3) Molecular evolution and adaptation (lampreys and endemic freshwater fish, Procellariiform seabirds, Australian skinks, weasels); and 4) Evolutionary processes in domestic animal populations (includes the study of genetic diversity and population structure of extant domestic species, particularly horses, cattle and dogs; archaeogenetics of Iberian domesticates; and the genetic basis of phenotypic variation in modern animals).

 

Key-words: Adaptation, Archaeogenetics, Epigenetics, Hybridization, Landscape Genetics, Phylogeography, Polyploidy, Population Genetics, Selection, Speciation.
