There’s definitely an element of evolution: domesticated animals have evolved to have human recognizable emotions. But that’s not to say they’re not “real” or even “human.” Do humans have a monopoly on joy? I think not. Watch a dog chase a ball. It clearly feels what we call joy in a very real sense.
Silly example, but some pets like guinea pigs are almost always hungry and they're famous for learning to squeak at you whenever you open the fridge or do anything that might lead to giving them bell peppers. It's not something you'd put up with a human family member using their communication skills to do!
