New research has shown how an ancient Maya city collapsed. It could also provide an explanation for the fall of the whole of the ancient civilisation.

The ancient city of Tikal, located in modern-day Guatemala, was once a major Maya population centre. It was also, in its pomp, a political powerhouse. From 600 to 850 CE, Tikal displayed unprecedented achievements in art, architecture and astronomy.

For many years, historians and researchers have been puzzled as to how Tikal was able to grow so vast. Supporting a large urban population was particularly difficult during the Late Classical Period. It would have been impossible for Tikal to import enough food to be sustainable; there were no draft animals, wheeled vehicles or waterways suitable for trade.
