Did poop enable the evolution of complex animals?
trilobite poop Did poop enable the evolution of complex animals? In a recent study, evolution gets even messier than usual. The first animals on Earth emerged about 600 million years ago, and 60 million years later, those simple early animals evolved into wildly different directions, branching out into a diverse menagerie of complicated new forms and conquering new ecological niches.
