For decades, students have been misled into believing that the ability to perform the seemingly arbitrary party trick of tongue rolling is determined by a single gene.
This misconception originated from geneticist Alfred Sturtevant’s studies in the 1940s and has persisted in biology classes for many years.
However, with the rise of the Internet, the truth has come to light.
In fact, Sturtevant’s theory was debunked as early as the 1950s through research on monozygotic twins. Recent studies suggest that anyone can learn to roll their tongue with dedicated practice.
The underlying issue may simply be that most individuals don’t bother to give it a try.
