Recent archaeological discoveries have revealed that the humble seabird guano, better known as bird droppings, played a powerful role in the rise of ancient pre-Incan societies in the Andes. Farmers in Peru’s Chincha Valley faced challenges cultivating crops in one of the driest areas on Earth, but the nutrient-rich guano shipped from offshore islands proved to be a game changer. It allowed them to grow maize in abundance, fueling their economy and establishing trade networks that flourished.
Dr. Jacob Bongers from the University of Sydney conducted a study analyzing maize samples from burial tombs in the region, uncovering high nitrogen levels that hinted at the use of guano as fertilizer. This agricultural surplus not only boosted local productivity but also strengthened ties between the Chincha Kingdom and the renowned Inca Empire. Who knew that bird poop could leave such a significant mark on history? It’s a testament to how nature’s byproducts can shape human civilization in the most unexpected ways.
