[Mother-child-relations from the anthropological point of view (author's transl)]

Some aspects of the ontogenetical process in the field of the mother-child-relations are discussed; the available answers to pertinent questions according to the actual level of knowledge are reviewed. The fact, that in torrid biotopes the increase of the body weight of the fetus towards the end of the fetal time is insignificant in proportion to comparison-values from the temporate zone is traced back predominantly to the effect of social factors (deficiencies in nourishment of the pregnant women). Also with regard to the regional and temporal differences in the conceptive frequency it is necessary for explanation to quote social factors besides climatic ones. Against the increasing radiant exposition of certain population groups objections are advanced in view of a potential damage to embryos and foetes. The teratogenetic effect of certain chemical factors and of the deficiency or shortage of nourishment of pregnant women are illustrated by means of examples. The problematic subject of the variability with age and gender of the colour of eyes and hair is delineated, the implementation of new comprehensive family inquiries is called for.
