I believe emotions are a fundamental entity in the universe. I don't believe they are unique to humans. I believe humans are an amalgamation of emotional development on behalf of bipedalism, opposable thumbs and just a whole lotta tiem. Thanks to Jordan Peterson i know that lobsters react the same way to SSRI's as humans. Even when you try to pick up a worm, it writhes and squirms as though it's in immense fear and desperation.
