| Anotation | Vertebrates as a taxon, that includes also human, are a biological assemblage with extraordinary variability, with large differences in life strategies as well as key adaptations, allowing the study of different aspects of evolution and get a more balanced view of its course. For example bats as flying mammals are able to colonize islands with relative ease and thus provide many cues for the study of island biogeography. Mammals of different body sizes evolved different strategies to take part in ecological networks, including trophic webs, which manifests as diversity in selection pressures, formation of corresponding adaptations and differences in macroevolutionary trends, such as e.g. formation of island syndrome. Loaches in turn dispose with remarkable evolutionary plasticity, when their interspecific hybrids have to cope with asexuality, adaptations to host species as well as climate changes or combining of evolutionarily distant genomes. These directions enabled also studies of phylogenetic relationships on the level of internal structure of animal orders and corresponding questions from the field of macroevolution and biogeography, contribute with help of multidisciplinary approach to study of questions from fields of allopatric, island and hybrid speciation, adaptive radiation, reproductive isolation and species interactions. Obtained information can be also useful from the point of view of natural preservation (identification of separated lineages). |
