The science and data are actually quite interesting. At its most basic, once we stopped grinding off our front teeth we were able to make a couple of new sounds. With longer front teeth our top teeth could touch our lower lip. Without that ability, you cannot make an F or V sound.
It seems like everything has to be made course now days. There are many words that begin with F and V but all the headlines only go to one particular expressive to grab folks interest.
I still chuckled the first time I saw a headline for this story. It got old when every news outlet was using the same hook.
