The Neolithic , the final division of the Stone Age, began about 12,000 years ago when the first development of farming appeared in the Epipalaeolithic Near East, and later in other parts of the world.

Diet of porridge and gruel shaped human faces, which diversified English language.

Changes to the human diet prompted by Neolithic advances in agriculture played a role in human jaw evolution that allowed people to pronounce the consonants F and V, researchers say.

Their work -- which combines linguistics, speech science and paleoanthropology and appears in the Thursday edition of the US journal Science -- indicates that language is not merely a random product of history but was also linked to biological changes at the time.

The Neolithic Revolution, Neolithic Demographic Transition, Agricultural Revolution, or First Agricultural Revolution was the wide-scale transition of many human cultures during the Neolithic

The Neolithic Subpluvial, also known as the African humid period or the Holocene Wet Phase, was an extended period (from about 7500–7000 BCE to about 3500–3000 BCE) of wet and rainy conditions in the climate history of northern Africa. It was both preceded and followed by much drier periods.

The Neolithic era -- spanning from 6,000 to 2,100 BC -- was when wheat and barley-based farming took root and animals such as goats, sheep and cows, were domesticated.

"Language is not usually studied as a biological phenomenon and it does not normally figure in, say, the curriculum of biology," said Balthasar Bickel, a researcher at the University of Zurich.

"If you think about it, however, this is a bit strange actually, because like the communication system of other animals, language is simply part of our nature," he stressed.

Man, before the Neolithic era, used his teeth quickly to chew the products of his hunting and gathering.

While the upper incisors covered the lower ones in children, wear and tear led to an "edge-to-edge bite" in adults, prehistoric skulls show -- positioning that made it difficult to make certain sounds.

Yogurt , yoghurt or yoghourt (/ˈjoʊɡərt/ or /ˈjɒɡərt/; from Turkish: yoğurt ) is a food produced by bacterial fermentation of milk. The bacteria used to make yogurt are known as yogurt cultures.

Tips and techniques on how to teach a child the f and v sound in syllables, sentences, stories and conversation. Think of syllables as a baby step that helps make the transition from isolation to words a little smoother. Practicing words in syllables can also help determine in which position of words

If you pull in your lower jaw until your upper and lower teeth touch each other, and then try to pronounce "f" and "v", it's very difficult.

The sounds are called labiodental consonants, which require the combined action of the lower lip and the upper teeth.

- Nature and culture -

Starting in the Neolithic era, hunter-gatherers learned techniques to process food -- for example, by milling it and cooking it.

"There were chiefly types of gruel or porridge, stews and soups, but also daily products like milk, cheese and yogurt that came about through food processing technologies that led to the softer diets," said Bickel's colleague Steven Moran.

"And an important thing here was the spread of pottery for preserving food, something that became very important with the introduction of agriculture."

Dental wear-and-tear was curtailed thanks to the softer diet, and the upper incisors maintained their adolescent position: over the lower teeth, as in today's humans.

It is important to understand their differences. Learn how to correctly pronounce F and V sounds with these explanations, videos, and exercises. In English, the F and V sounds are often studied together because they are produced in the same part of the mouth. They both are consonant fricatives too.

Researchers say they spent five years on the study.

In the final phase, they studied the history of Indo-European languages and concluded that it was "very likely the labiodentals emerged not much before the Bronze Age, in parallel to development of food processing techniques," explained another co-author, Damian Blasi.

The Bronze Age followed the Neolithic.

"Our findings suggest that language is shaped not only by the contingencies of its history, but also by culturally induced changes in human biology," the researchers wrote.

"We can no longer take for granted that the diversity of speech has remained stable since the emergence of Homo sapiens."

Blasi said he hoped the study would spark a "wider discussion" on how some aspects of language and speech "need to be treated as we treat other complex human behaviors lying between biology and culture."
