Human speech contains more than 2,000 different sounds, from the common "m" and "a" to
the rare clicks of some southern African languages. But why are certain sounds more common than
others? A ground-breaking, five-year study shows that diet-related changes in human bite led to
new speech sounds that are now found in half the world's languages.
More than 30 years ago, the scholar Charles Hockett noted that speech sounds called
labiodentals, such as "f" and "v", were more common in the languages of societies that ate softer
foods. Now a team of researchers led by Damián Blasi at the University of Zurich, Switzerland, has
found how and why this trend arose.
They discovered that the upper and lower front teeth of ancient human adults were aligned(对
齐), making it hard to produce labiodentals, which are formed by touching the lower lip to the
upper teeth. Later, our jaws changed to an overbite structure(结构), making it easier to produce
such sounds.
The team showed that this change in bite was connected with the development of agriculture
in the Neolithic period. Food became easier to chew at this point. The jawbone didn't have to do as
much work and so didn't grow to be so large.
Analyses of a language database also confirmed that there was a global change in the sound of
world languages after the Neolithic age, with the use of "f" and "v" increasing remarkably during
the last few thousand years. These sounds are still not found in the languages of many hunter
gatherer people today.
This research overturns the popular view that all human speech sounds were present whenhuman beings evolved around 300,000 years ago. "The set of speech sounds we use has not
necessarily remained stable since the appearance of human beings, but rather the huge variety of
speech sounds that we find today is the product of a complex interplay of things like biological
change and cultural evolution," said Steven Moran, a member of the research team.

A. Supporting evidence for the research results.

D. A reasonable doubt about the research process.
35. What does Steven Moran say about the set of human speech sounds?
A. It is key to effective communication.
B. It contributes much to cultural diversity.
