Languages can definitely change and they can diverge. For example, Latin split up into the modern Romance languages: Portuguese, Spanish, Romanian, Galician, etc. This is less known, but languages can also converge: those languages are called creole. Some people argue that English is also similar to a creole: a mix of Germanic and French.
Language convergence: collapsing of two languages into one resulting from the consistent spatial interaction of peoples with different languages. Language replacement (extinction): obliteration of an entire culture through war, disease, assimilation, or any combination of the three.
