    Beavers in captivity will dam over a speaker which makes the sound of running water, which researches then tested extensively to prove Beavers’ instinct to dam is triggered by the urge to make the sound of running water stop.

    I like to imagine the beaver’s ancestor was a really big neuroatypical rat who one day was like "I hate this sound and will throw sticks at it until it stops.
