• Resumen

  • Strange and largely immobile organisms living on the seafloor were the first complex life on Earth. Appearing 579 million years ago, they thrived for some 37 million years, then vanished--becoming a curiosity people know only from faint impressions in the sandstone fossil record. New fossil evidence suggests that these creatures, known as Ediacarans, had their world turned upside by an explosion of life forms at the start of the Cambrian period 541 million years ago. Some may have evolved to eat their enigmatic predecessors, and may also have changed the environment in ways that doomed them.
