It has always been strange to me that anyone would think animals don’t have a wide range of emotions. I understand that a scientist can’t ask how an animal is feeling, and must instead record avoidance/seeking behaviors, but it also seems vanishingly improbable that emotions aren’t part of a long and useful evolutionary methodology to get to the next generation. Cows have friends. Sure, it took effort to prove, but why wouldn’t we expect that? We see mothers nurture their offspring, and we could easily call it love and concern. It is good to see we now have proof that it isn’t just the cuddly creatures with emotions, but at least as far down the scale as fish.
