Much of what we know about the diversification of body plans that happened starting 540-million years ago (commonly known as the Cambrian Explosion) comes from the famous Burgess Shale formation.
A new study provides substantial support for earlier claims of 520-million-year-old arthropod brain systems, raising interesting questions about the nature of brains, life and intelligence in the cosmos
