I meant the development of written languages happened independently across different regions of the world, and of course at some point, languages became mutually unintelligible, and language changes within the languages happened differently.

And while of course every language descends from another, and ancient Chinese isn't understandable to a modern Chinese speaker, there is a long tradition within the Chinese language, and change within the language hasn't been shaped by things as drastic as displacement of the linguistic community, or forced political rule under a foreign power, etc.
