What’s the reason 16.3 of the population unable to roll their tongue?
In: Biology
We learn how to produce different sounds with our mouth at a young age. And then this gets cemented into the language portion of your brain and becomes very hard to change. This means that we can easily learn a language when we are young and we can very quickly use that language when we are older. But it also means that it is very hard to learn languages after you have grown up, especially if these use different sounds then you know how to make. The problem is that a lot of people did not hear people roll their tongue when they grew up or at least not in a way that they could not approximate using different techniques then rolling their tounge. So they never learnt how to, and it is a skill that is very hard to learn after they have grown up.
