| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily. |
| 0:04.8 | From Curiosity.com, I'm Cody Goff. |
| 0:07.0 | And I'm Ashley Hamer. |
| 0:08.1 | Today you learn about how sleep may have evolved before the brain did, why airports keep birds of prey on staff? And what |
| 0:15.5 | would happen if you stopped time? Let's satisfy some curiosity. I get it. Yeah, |
| 0:22.4 | I stopped it. Yeah, I stopped time. |
| 0:24.5 | Quick question for you. Why do we sleep? I mean, it seems safe to say that the answer has something to do with our brains. |
| 0:32.0 | That's why this next sentence is so |
| 0:34.8 | mind-blowing. New evidence suggests that sleep might have evolved before |
| 0:40.2 | brains. This is counterintuitive, to say the least. |
| 0:45.0 | I mean, everybody has had those nights where you didn't sleep well and you had to fight through |
| 0:48.6 | brain fog the next day. |
| 0:50.8 | And the longer we go without sleep, the worse this gets. |
| 0:54.0 | Just 24 hours of sleep deprivation is all it takes for the average human to start experiencing minor hallucinations. |
| 1:01.0 | So even though we know sleep is good for our health because we can see the bad things |
| 1:06.1 | that happen without it, there's still no definitive answer as to why we do it. |
| 1:12.0 | But here's the weirdest part. Researchers studying the evolution of sleep have |
| 1:16.1 | found tiny animal cousins to jellyfish that regularly enter sleep-like states, even though they don't have brains or central nervous systems, yet |
| 1:26.9 | they seem to benefit from sleeping. |
| 1:30.3 | These tiny creatures are known as hydras, not to be confused with the mythological multi-headed |
| 1:35.3 | serpent-like monster with the same name. In a recent study, researchers were able to observe |
| 1:40.8 | these tiny little hydras entering a sleep-like state every four hours, where they |
