Nature has given us one tongue but two ears that we may hear from others twice as much as we speak?

Is tongue rolling recessive?
If you are asking whether or not tongue rolling is recessive trait, the answer is no. Tongue rolling is dependent on nurture, rather than nature. In many languages, tongue rolling is used to pronounce words correctly. It is a learned behavior rather than an inherited trait or gene. This is not the case when using the English language (which I will assume you speak because the question was asked in English).
