The specific feature of humans, that distinguishes them from the animal world, is the speech. The speech is a form of communication in which we use comprehensive signs to express verbally ourselves and the surrounding reality. This definition imposes the opinion that the origin of the speech can be considered from the appropriately high level of the brain development. In order to trace the evolution of the ability to speak among the Primates, the measurements of the superofacial triangle of the...
Evolutionary radiation of primates determined many developmental paths among which there is a hominization tendency that leads to the emergence of modern human. This evolution was studied on the basis of measurements constituting Morant and Sergi’s index (Sergi(1940)), which were taken on 68 skulls of chosen adult monkeys, apes and fossil hominids. They were classified into 10 separate taxons. The skull measurements were worked out with the help of the following methods: descriptive statistics and...
The aim of this work is to present taxons which link various species and genera as morphological stages in the evolution of primates. The research material consists of 115 skulls of monkeys and apes. Their variability in neurocranium and splanchnocranium ratios can be characterized by Morant and Sergi’s index and by direct measurements that is formed of. The analysis of results allows the following conclusions. Determining taxon concerning PAPIO (baboons) shows that sex dimorphism exceeds differences...
