[Evaluation of biological variables in the human].

The analysis of the biological variability is one of the most important problems of anthropology and human genetics. However, describing the objective reality a conscious or unconscious valuation of this reality comes of frequently. Such a valuation can be motivated in a very different way and can achieve a considerable importance concerning the view of man. Experiences from history and presence make it clear that the sensitiveness for these problems must be a never renounced and a constant concern of all anthropologists and human genetists.
