How the 'fecal revolution' reshaped Earth's ecosystems

How the 'fecal revolution' changed Earth's ecosystems

A new study reveals how the evolution of feces—from simple waste to nutrient-rich deposits—dramatically transformed Earth's ecosystems. Researchers trace the 'fecal revolution' back to the rise of large animals, whose dung became a key resource for plants, insects, and microbes, ultimately boosting biodiversity and soil fertility. The findings highlight the often-overlooked role of animal waste in shaping the planet's life-support systems.
