The chronology of Genesis in relation to language

Based on the following verses... **Genesis 10:5** (From these the maritime peoples spread out into their territories by their clans within their nations, each with its own language.) The Hamites **Genesis 10:31** These are the sons of Shem by their clans and languages, in their territories and nations. **Genesis 11:1** Now the whole world had one language and a common speech. ...can we assume (or is it simply a fact) that Genesis is not chronological?
