A 4,000-year-old network of earthen canals was discovered in Belize’s Crooked Tree Wildlife Sanctuary, revealing how ancient societies modified landscapes in Central America’s Yucatan Peninsula. The discovery, published in Science Advances on Friday, was made using drones and Google Earth satellite images. Built by semi-nomadic people during the early Maya civilization, the canals were used for over 1,000 years to trap freshwater fish like catfish. This period marked the rise of permanent farming villages and a distinct cultural identity. Aerial images showed zigzag canal patterns stretching for miles, indicating advanced environmental manipulation.

Excavations showed that the canals helped trap fish and supported resource management. Artifacts, such as barbed spear points, suggested that spearfishing was common, with tools likely attached to sticks for easier hunting. This canal system diversified diets and supported population growth, laying the foundation for future cultural progress. Experts said these environmental changes reflected sophisticated societal organization. The discovery highlights a continuous link between early societies and the later Maya civilization, offering valuable insights into the region’s development and the early inhabitants’ control over their environment.
