Figuring out exactly when people started to separate into different social strata is one of the tricky, nebulous areas of archaeological research. When and why did humans move from egalitarianism to inherited land, wealth, and power? And now, new evidence suggests that we already had social classes as long ago as 7,000 years ago, in the midst of the stone age. (via Do class divisions go all the way back to the Stone Age?)
