Well, actually languages behave a lot like living things, when 2 parts of the world that speak the same language are appart (culturally I mean, it can be because of distance or lack of frequent contact...) for too long they start to modify words, grammar structures etc... And at some point become so much different that they can't even understand each other. So you kinda can represent languages on phylogenetic trees where you group languages from their relatedness. Languages evolve much faster than species though (if you except the "simple" lifeforms like bacteria or virus)
Actually, I believe the different nations that speak Arabic will probably develop their own language at some point. Much like the Romance languages are now different languages though they all evolved from classical Latin.
