@Eli G , more about languages.
The theory of Evolution is about mechanisms for changes and speciation. These changes are that of physical traits, and it require any physical changes should be passed on from parents to offspring, and over generations, to descendants.
Hence, Evolution is very much about genetics, hence it’s about biology.
Languages, on the other hand, are taught and learned, and more importantly, languages have more to with respective cultures, not biology. Whether it be spoken or written, languages are not imprinted in human DNA.
It is is absurd that you would bring up languages on the matter about evolution, as they are unrelated.
For instance, if you grew up in France, and spoke French that because you have learned it. But the French language wouldn't be encoded in your DNA, and you won't pass it on genetically to your children, because it would be something they would learn from, where they grew up.
And if you married someone who grew up speaking Polish or Greek, you and your spouse wouldn't be of different species, if you two spoke different languages. As I said, earlier, languages are not learned processes, not biological traits.
Do you understand what I am saying?
Languages are linguistics, not biology, so the theory of Evolution don't apply to spoken languages, but yes, languages and dialects can over changed over time, or differed from region to region, but none of the languages are encoded in one person's DNA, so languages are not inheritable traits, genetically.
