Why not? Lots of animal species will have unique physiological reactions and responses as a consequence of their individual evolutionary development. Humans have a lot of significant unique characteristics (notably our intelligence) to influence this kind of characteristic. To be honest, I think it’s more interesting how many things we have in common with other animals.The universal existence of blushing as an expression of shame appears to exist only among humans. No other species does it - yet we do so involuntarily, either from shame, guilt or embarrassment.
Why?
