Sleep evolved before the central nervous system?!?!? Listened to a back log of @tpwky.bsky.social episode and 🤯🤯🤯 this is a great quanta article to go with the sleep episode. I love science www.quantamagazine.org/sleep-evolve...
Studies of sleep are usually neurological. But some of nature’s simplest animals suggest that sleep evolved for metabolic reasons, long before brains even existed.
