【正确答案】
The fact known to us is that war, different from what many people believe it to be, is not completely an outcome of "humanity". Otherwise, war and violence among people would exist in all the human history or almost all societies. However, this is not the truth. Archaeologists' investigation results seem to suggest that men lived quite a peaceful life long ago. For example, among ancient French cave drawings which were earlier than 10,000 B. C., there were no pictures describing people fighting with each other. This indicates that, in that early period of mankind, fight among people was comparatively rare. In a certain way, this discovery is not surprising at all: in the world of animals, it's rare for one to prey on another of its own species. They do kill other kinds of animals, but not their own. Like most animals, the proportion of inner violence among early human beings was relatively small. Therefore, war is not the inherent outcome of humanity but that of certain social and cultural conditions.
