Does phylogenetic proximity positively correlates with the likelihood of an evolutionary origin of mimicry?
 Kováčová, Katarína ; Kleisner, Karel (advisor) ; Raška, Jan (referee)
Mimicry represents a diverse group of similarities, which belongs to the phenomena of evolutionary biology. Even though mimicry is often interpreted as a convincing exam- ple of natural selection, it is necessary to consider the morphological and organizational processes that are responsible for the formation of organisms. In our work, we tested the hypothesis that mimicry occurs more frequently among insect genus that are phylogenet- ically closer than those that are phylogenetically more distant. To elaborate the work, we used 112 genus from the Insecta and Arachnida classes. The hypothesis was tested glob- ally, continentally and at the order level. Our hypothesis has not been refuted in Central and South America, Asia and Australia. At the order level, it was not contradicted in the order of Lepidoptera. We hypothesize that the explanation can be deduced from radical phenotypic changes that would ultimately disadvantage the given organism. 1
