How come that all around the world the same voice inflexion is used when asking a question?

Question

you know, everytime you ask a question your voice has a specific inflexion, less monotonous than an ordinary sentence. does it have something to do with an originary root for all languages?

Answer 1

probably, it's like a vocal posturing, audibly known to be a question without understanding what was said. Like the family dog calling out. The inflection in greeting friends and family being different from that of strangers, or different yet those of invading creatures. If you pay enough attention to him you will very often understand him. And in communicating with a language barrier in place, we almost always revert to voice inflection and body posturing to communicate. With people as well as animals.

Answer 2

No, it has something to do with the mechanism of all languages being innate and the same. Chomsky's " universal grammar ". All humans are prepped to language, whether in the verb/noun or noun/verb direction. We are evolved to speak a language; the local language is mapped on to this innate mechanism. Google Noam Chomsky.
