The evolution of sleep may or may not predate the evolution of brains. It might have evolved twice, once in predecessors of hydras and once in predecessors of beings with brains.

- jfengel 5y agoIt's amazing how bad our brains can be, even after a few million years of evolution. They're capable of flying a helicopter on Mars and cranking out a vaccine within months, as well as developing vast machines containing zettabytes of information -- and still can't retain a word for 15 seconds.
- periheli0n 5y agoAll the amazing capabilities you mention are the result of cooperation between dozens, hundreds or even thousands of humans. Without doubt, individual people made millions of errors in the process, and each time some other contributor caught it. Single brains can only do that much, great things are the product of cooperation between humans.
