No-Brainer

“Getting rid of your brain sounds like a bad idea.”

It says a lot about the cosmos that evolution seems to disagree.

The oldest known fossil with a complex brain is about 520 million years old. This was a time when life became much more abundant and diverse, often referred to as the Cambrian explosion. […] Discovered in China, the animal looked like a woodlouse with claws. It seems to have had an elaborate brain-like structure consisting of a fore-, mid- and hind-brain, all of which had specialised neural circuits. […] This suggests that complex brains were in place as early as 520 million years ago. But they may not have stayed.
