"But it was not easy for our monkey-like ancestors to reach REM sleep.
They slept on branches, and their nights were anything but easy.
As monkeys try to sleep today, they get roused by winds, tree snakes and the jostling of their fellow primates."

... also they don't brush their teefs and hair before bedtime.....

On the other hand, they don't do this before bedtime ...

Love all the animated pics, especially the monkey grooming.

If you picture a row of ducks on a log, all sleeping, the ones in the center have both eyes closed while the two on either end have one eye open. However, these two ducks are sleeping too! Most animals--according to some show on NPR that I'm probably mis-remembering--only sleep with one eye shut. this means that only one half of their brain is asleep. they need to keep one eye open because of predators. It was said that only mammals who had secure sleeping areas, probably underground, could afford to sleep with both eyes closed and so enter a deeper level of sleep.

I'll just wait for someone who knows more than me about this to correct my statements. I heard the show a while ago and I've probably gotten points wrong.

Here is a discussion of a list of animals that sleep half a brain at a time - https://www.quora.com/Which-animals-sle ... -at-a-time

What about animals that sleep with both eyes open? All animals with eyes but no eyelids will be sleeping with their eyes open. Common ones with which you probably already have experience would be all fish, all snakes, insects, crustaceans (crabs, shrimp/prawns) and so on. In fact, the majority of animals on earth lack eyelids, so most animals sleep with their eyes open. The minority of animals include the mammals, birds, lizards, crocodilians, & turtles that do have eyelids.
