Science actually figured this one out. Beavers raised in captivity when exposed to a speaker playing river noises will cover it up with as much stuff as possible to hide the noise. So it's the noise they have an issue with
Then why not live away from the river or maybe in a lake?
They require ponds to live safely. They build dams which create ponds. Then they build little mound houses out of sticks and mud in the middle of the pond. The house only has underwater entrances. They can cut trees down and float them into the pond, where it is safer to eat. They're mostly aquatic mammals.
Suddenly the angry beavers makes more sense
I see you've met my ex wives.
So its not just the sound, got it
It's the sound that triggers an instinctual response.
Correlation, not necessarily causation.
Idk man, ask a beaver
They have been known to live in lakes, and when they do they dig dens under the shoreline.
The reason they don't like the sound of running water is the same reason we don't like to hear the sound of unexplained running water in our homes, it's a sign of a leak. The only difference is for them it's instinctual, and for us we understand the consequences of a leak in our home.
That's just quitter talk.
Because they are dumbasses
"Hey Bob, I see you hired a plumber, what's going on?"
"I heard the sound of a leak in our bathroom wall. Hired a plumber to find it and fix it."
"You're such a dumbass, Bob."
More like: I heard dripping water in this movie I was watching, so I hired a plumber
It's weird how people whose entire life has been lived with imax can't fathom the millions of years the earth evolved without tiktok.
Lol
While working as engineers, beavers still can't afford to live in the city considering the high cost for housing.
It's like me when someone plays their music out-loud on the bus. They always seem to get angry when I start wrapping their phone up with newspaper.
Here I was hoping you threw it into a river shouting 'dam it' for extra pun-ishment.
This is fascinating, but what's the evolutionary advantage of covering up the noise?
Covering the noise is covering the running water. Covering the running water creates a dam. Creating a dam creates a pond. Creating a pond provides them with a nice controlled environment in which to build a lodge with an underwater entrance for protection from predators.
It's like no one ever watched The Angry Beavers
Running water means you can block it off to create a reservoir. Evolution isn't about what makes sense, it's about what works, logic be damned.
DAMMED

Oh, it's from a book.
There is a norwegian study that found that isolated beaver babies start piling up sticks and stuff at some point but do not build dams. They concluded (the scientists) that piling up stuff is genetic and building dams is cultural (has to be learned). I have no link but the study was made in Bø
Baby animal studies focused on play are always so cool. Like bees appearantly will play with objects that have nothing to do with their survival.
We do the same thing I think. Kids will pile up or mess about with any stuff you give them whether they have a cultural understanding of it's use or not.
