More and more, it looks like he was right.
Writing did not arrive in this part of Europe for another 2,000 years, so it’s a mystery as to who was fighting whom. A full DNA analysis has yet to be completed, but evidence from teeth indicates that this was no local struggle. Instead, the chemical composition of the teeth show that the men came from many different parts of Europe, some from hundreds of miles away.Let me tell you of the days of high adventure.
One hypothesis suggests that bands of warriors were brought together for a common purpose, in the same way warbands came together in the story of siege of Troy.
But what’s really startling historians is that nobody knew North European society was this organized, stratified and warlike so early in history. One researcher told Science magazine “if you fight with body armor and helmet and corselet, you need daily training or you can’t move. … This kind of training is the beginning of a specialized group of warriors.”
An elite warrior class can only exist if someone else is growing the warriors' food and making their weapons and tools. That suggests a degree of hitherto unsuspected stratification of Bronze Age society.
