Half a billion years ago, as the first complex animals proliferated across a young Earth, their most mundane biological act — producing waste — may have quietly engineered the conditions for all that followed. During the Cambrian period, animal feces introduced unprecedented volumes of nitrogen, phosphorus, and chemically active material into oceans and onto land, rewiring nutrient cycles and altering atmospheric oxygen in ways that opened new ecological possibilities. Scientists are now recognizing that this overlooked 'fecal revolution' was not a footnote to evolution, but perhaps one of its
