[Structure of the skull in early man as an expression of his life in the forest and his subsequent development].
Against the general theory, evolution of man happened in the steppe, the present study takes in view the hypothesis, that it took place in the wood. The idea of an immediate settlement of the steppe by the anthropoid ape-like prehominidian after having entirely left the zone of treetop is improbable, because this hitherto predominant occupant of tree was still strongly handicaped in bipedal walk. Besides he would have been removed into a for him extremely strange landscape, a drinkwater- and shadow-poor hot living space, the high risk of existence of it he was not able to overcome without experience, sufficient quick adaptability and without any technical ability to defence against wild beasts. The development of the special skull structures of fossil early man forms, especially those of the Tori supraorbitales, the Torus occipitalis, the thickness of the wall and the considerable length of the skull, seems only have been possible in a phylogenetic long living in the wood by elimination of populations, which mostly were not seriously damageable any more by contusions of branches and falling branches. With regard to the question concerning the geographical region of man's origin apparently could only South-Asia make available the necessary local environmental conditions, which were offered there by reason of active tectonics during the Miocene and the Pliocene by corresponding change of climate. These repeatedly occuring depressions of climate caused by accumulated crisis of existence a hard selection of adaptive pre- and early man forms increasing of a higher degree. In the remaining continents of the Old World had obviously been missing the active geotectonic impulsion, which necessary for the development of the higher vertebrates and the man.
