It is totally wrong to assume that we have advanced as a society. We have only advanced technologically while human nature remains unchanged. The transition from game hunting to agriculture and stock-raising marks the start of the neolithic period, that is, the late stone age. In 2005, a necropolis around 4,600 years old was found in Eulau near Naumburg (Saxony-Anhalt); there were 12 graves, each of which contained up to four burials. Detailed laboratory analyses showed that all those buried had suffered a violent death. Yet we have families buried together and the bodies were all positioned facing south for some religious or cultural reason. What this illustrates is that human nature has not changed – only technology.
