| Anotation | Already Darwin in the year 1859 pointed out in his theory that species are not invariable, but that they rather result from long-lasting progressive process, i.e. evolution. Evolution of vertebrates, as well as of any other animal taxa, results from permanently ongoing interactions between the living organisms and more or less stable environmental conditions. Indeed, the variety of climatic and other environmental conditions represents the ultimate cause of origin of many evolutionary novelties. The vertebrates group have undergone through many radiation periods during their evolution. At that time there was a diversification of many body-plans adapted to different environmental conditions. Devon can be understanded as one of the most important periods in their evolution, when many lineages of fish were radiated and the vertebrates started crossing the land. Another key period is after the Cenozoic, which occurred after the big Cretaceous extinction event to the extinction of large dinosaurs forms. Their crash meant the release of significant ecological niche and implied the dawn of modern mammals. Due to their evolutionary past and above all the current species variability, the vertebrate animals are an interesting taxonomic group that offers many opportunities for studying adaptations and adaptation mechanisms, but especially the opportunity to study population dynamics or specialization mechanisms. Within the project we will use genetic, genomic, geographic and also bioacoustic approach in selected vertebrate groups. The obtained information will be used to study the genetic structure of populations, gene flow among populations as well as the phenomenon of interspecific hybridization. Our aim is to contribute to the understanding of evolutionary processes and mechanisms that have created and are still creating the genetic structure of populations and the species richness of all vertebrates. |
