The New York Times has published an interesting story [nytimes.com]:

Thousands of years ago, some of our ancestors left behind the hunter-gatherer lifestyle and started to settle down. They grew vegetables and grains for stews or porridge, kept cows for milk and turned it into cheese, and shaped clay into storage pots.

Had they not done those things, would we speak the languages and make the sounds that we now hear today? Probably not, suggests a study published Thursday in Science.

“Certain sounds like these ‘f’ sounds are recent, and we can say with fairly good confidence that 20,000 or 100,000 years ago, these sounds just simply didn’t exist,” said Balthasar Bickel, a linguist at the University of Zurich and an author of the new research.

The study concluded that the transition to eating softer foods changed how bites developed as people aged. The physical changes, the authors said, made it slightly easier for farmers to make certain sounds, like “f” and “v.”
