New findings in horse phylogeny

This thesis deals phylogenetic developement of the horse since its origin until the present. Describes fossil horses, formation processes and conservation. Shows the most famous paleontological localities, where they were found fossil bones or fragments. Explains methods of investigation, such as determining the age of radiocarbon dating or electron spin resonance and analysis ancient DNA. Family equidae is taxonomically classified based on their evolutionary series. Relations between taxa are also shown in the diagrams - phylogenetic trees or cladogram, which are structured according to morphological and molecular data. It also mentions order Perrisodactyla, their evolution, radiation and new taxonomic classification. The main part is devoted to phylogeny equidae. It describes morphological changes due to adaptive specializations, including mainly limbs (extension their parts and reduction fingers), dentition (increasing crowns, molarization of premolars, gradual coverage cement) and skull (extension and enlargement of the brain). It describes individual genera and several important species from the genus Hyracotherium after Equus, their morphology and way of life. Previous studies of fossil horses, methods of comparative anatomy, are confronted with new molecular biology analysis. The results bring a new perspective on the taxonomy and phylogeny of the horse. Next part is devoted breeding groups of domestic horse. Characterized Eguus robustus, Equus gracilis, Equus gmelini and Equus przewalskii. Detects the taxonomic status of the Przewalski horse, relative to fact that today there are disputes about its evolutionary relationship with the domestic horse. Highlights the importance of reintroduction of Przewalski horses, the last wild horse, in the Mongolian steppes, the place of his original expansion. The last part includes the theory of horse domestication. Describes the site of human habitation, where archaeological artifacts and horse bones indicate keeping animals
