Peer-polity interaction models see the primary driver of change as the relationships and contacts between societies of relatively equal standing. According to the model set out by Renfrew,[2] it encompasses three main sorts of interaction:
Symbolic entrainment, where societies borrow symbolic systems wholesale from their neighbours, such as numerical systems, social structures and religious beliefs, because these fill a currently empty niche in their society.
Transmission of innovation, where technology spreads by trade, gift-giving, and other forms of exchange.
