No Bosses: Ancient Engineering Marvel Was Built Without Rulers, Study Suggests
These multipurpose structures absorbed water during heavy rains and released it during dry seasons, creating a water management system that prevented both flooding and droughts. Now, a team of scientists has used satellite imagery to map a 1,200-acre patch of the system in unprecedented detail. With that sample, they built a model to estimate the population and labor costs of construction in that area.

🌘Subscribe to 404 Media to get The Abstract, our newsletter about the most exciting and mind-boggling science news and studies of the week. Ancient people of Colombia used collective labor to build a massive canal network that spans 2,000 square miles, a discovery that challenges the assumption that colossal works require top-down hierarchical social organization, reports a study published on Monday in Communications Sustainability.From the first century BC to the 11th century, Colombian peoples living in the La Mojana lowlands sculpted their wetland environment by building raised fields, ridges, and canals, which are today referred to as the Zenú hydraulic systems after the culture that built them.
