We always think so lowly of other animals, so this isn’t surprising.
Animal-like intelligence in humans is far more common than we thought

Rats are known to be more intelligent than us. When it comes to problem solving in as short a time as possible they win. Humans are not the samrtest animals, we are the animals capable of learning through abstract means. Our brains can encode lessons and decode them with nothing more than language. That’s what separates us. We thankfully have less need of intelligence than other animals. Despite appearances, we are the wisest animals rather than the smartest.
Not only humans can use language to impart abstract concepts. Crows have been observed sharing information about danger to crows who are not present to witness the danger themselves, but then successfully recognize it in the future. They’ve also been found to be able to create tools they have not seen before in order to solve problems.
Koko the gorilla was also famous for her abstract thinking. Others species include dolphins and elephants, and obviously we haven’t tested most species out there.
Songbirds fascinate me. I hope we can decode some crow oral history one day.
