When we look back upon man's long past, the following question occurs: how and by what processes has this being, which we call man, come to be what be is to-day? It is only through a long and gradual process of many hundreds of thousand years, subsequent to a long biological evolution, that this living organism called Man has become man in the modern, cultural sense of the word. This means that, in the life-time of man as a species, an evolution in the cultural sense of the word has been added to the biological one: the transition from a man-like being to one that can truely be called man, the emergence of cultural elements juxtaposed to the biological ones and in time gaining in importance; that is what we bere, to-day, mean by culture history.
