How are all the animal languages universal?
I don't believe that they are...
If your tackling this problem from a philosophically interconnected point of view - I'm not the person to ask. However, if you are coming from a scientific point of view - I can help you here.
When animals communicate, they are essentially speaking a language, which can come in both verbal and physical forms. As of yet, scientists have been unable to find any verbal evidence of existing languages across a large range on test subjects in a specific species or genus of animals.
However, unlike most animals, humans live in a somewhat "civilized" society and urbanized environment as such where we have been given time to develop and establish multiple forms of verbal communication. In other words, we are no longer animals that use hunter gathering methods such as lions, dingoes and other pack animals.
Instead, we live by a certain set of human laws developed over time that mean we can't have sexual relations with another if engaged in a current sexual relationship etc. etc.
This is not the same for the wild.
In such an environment, human rules don't apply. Consequently, there is more of a "pecking order" where animals of the same species may kill to survive. In other words, instinct and chemical reactions that occur with these animals bodies are used over human methods such as going to court etc. Furthermore, since wild animals are considered "wild", it is harder for mass groups of them to interact unlike humans. Therefore, they rely more on physical communication rather than the verbal communication that is preferred by animals known as humans.
All the best!
