Diachronic changes in the morphology and sexual dimorphism of the skull in the territory of Bohemia and Moravia
Letošníková, Lenka ; Bejdová, Šárka (advisor) ; Rmoutilová, Rebeka (referee)
This diploma thesis is devoted to diachronic changes in skull morphology and sexual dimorphism of the early modern and recent population from the territory of Bohemia and Moravia. The two populations are roughly 500 years apart in time, so it can be assumed that each group was affected by different environmental influences. While individuals from the early modern period, coming from the middle class, are assumed to be affected by unfavorable living conditions (insufficient hygiene, malnutrition, etc.), the recent population is exposed to more favorable socioeconomic conditions. A number of studies agree that quality living conditions have an effect on the morphology of the skull in the sense of narrowing and increasing the cranial vault, and at the same time have a positive effect on the manifestation of sexual dimorphism. The aim of this thesis is to evaluate the variability and degree of sexual dimorphism in skull morphology and to describe diachronic changes of the skull in early modern and recent populations. According to the established hypotheses, we assume that the skull of the recent population will have a higher and narrower cranial vault and facial part as a result of the improvement of living conditions and will show more pronounced sexual dimorphism. A total of 174 skulls were analyzed...
Bipedal locomotion of primates: ecological, ontogenetic, and morphological aspects
Letošníková, Lenka ; Hora, Martin (advisor) ; Novák, Jan (referee)
In my bachelor's thesis I focus on bipedal locomotion and bipedal posture of various primate species in a morphological, ontogenetic and ecological context. Nowadays, a habitual bipedalism is used only by human, about whom I mention only marginally with comparing him to the other primates in my thesis. First part of thesis deals with morphological aspects of bipedal primate locomotion, including description of anatomical differences of primate species and comparison of bipedal walk to quadrupedal walk. Next in thesis, I deal with ontogenetic aspects of bipedal primate locomotion, where I compare the rate of bipedal use among infant and adult primates and also among selected primate species. Finally, I describe the use of bipedal walk and bipedal postures of primates in different situations and ecological conditions. Keywords: bipedalism, primates, primate locomotion, ontogenetic aspects, morphology, ecological aspects, transport, human
