Vznik nových druhů probíhá převážně štěpnou speciací. Nicméně poslední dobou přibývají důkazy o přítomnosti hybridní speciace, tedy vzniku nového druhu zkřížením dvou odlišných rodičovských druhů a to nejen u rostlin, ale i u živočichů. Cílem této práce je shrnout poznatky o hybridní speciaci a popsat jednotlivé příklady výskytu hybridní speciace u živočichů. U živočichů se vyskytuje zejména homoploidní hybridní speciace, při které se nemění počet chromozomálních sad. Zjistila jsem 23 hybridních druhů živočichů vzniklých homoploidní hybridní speciací. Většinu z nich tvořili zástupci hmyzu a ryb, ale příklady se nalezly i u zástupců ptáků a savců. Vznik druhů hybridní speciací u živočichů se zdá být častější, než se myslelo. Powered by TCPDF...
