Embryo Fossils Reveal Animal Complexity 10 Million Years Before Cambrian Explosion

Fossilized embryos predating the Cambrian Explosion by 10 million years provide evidence that early animals had already begun to adopt some of the structures and processes seen in today's embryos, say researchers from Indiana University Bloomington and nine other institutions in this week's Science. James Hagadorn of Amherst College led the multi-disciplinary international collaborative project.
