Some cities only last a century or two, while others last for a thousand years or more. Often, there aren’t clear records left behind to explain why. Instead, archaeologists piece together clues from the cities’ remains to search for patterns that help account for why certain places retained their importance longer than others. In a new study published in the journal Frontiers in Ecology and Evolution, researchers examined 24 ancient cities in what’s now Mexico and found that the cities that lasted the longest showed indications of collective forms of governance, infrastructural investments, and cooperation between households.
