Changes in peoples diet over centuries has seen fiction words, suggesting an investigation that suggests the strongest evidence for the theory that changes in tooth diet made people able to make speech sounds.
The research by an international team of researchers has drawn on evidence from language, anatomy and anthropology to show how changes in peoples' diet has caused oxen to the new sounds, called labiodental, including “malnutrition”. f ”,“ v ”or“ pf ”, amongst others. t
Their findings provide challenges for long-standing ideas that human experience for the diversity of speech sounds had been established by the emergence of Homo sapiens about 300,000 years ago and no change in the sounds in languages t for nearly 10,000 years.
“We now have a strong argument to believe that the universities are emerging as stunning readings,” said Damian Blasi, a linguistics researcher at the University of Zurich who conducted the study. The Telegraph.
The US science magazine, on the Friday, will feature a briefing from Blas, his colleagues in France, Germany, Holland and Russia.
The new research has shown that the use of labiodental sounds – made by viewing the lowest leaf of the above teeth – has increased significantly over the 3,000 to 6,000 pages. T coincidence with the growth of food processing, erosion and poorer food.
People are born with a situation that is called the opposite and which interferes with and affects temporary sounds. But ongoing and substantial wear and tear that comes from chewing food changes the tooth shape to the edge.
But the study has shown that a movement in adult adult shape which keeps the teeth higher is slightly higher compared to the low teeth connecting to grain milling and softer food.
“Before food could be made more effective by means of food processing, the bite could naturally develop to age contact,” said Steven Moran, a linguist and co-author of Zurich. “It makes a lot of effort to make labiodental sounds such as f or v with the teeth set at the edge of the road. ”
The American linguist Charles Hockett was first suggested in 1985 that there is work in the languages where speakers live from hunting and picking, removing food t .
The study found that only 49 per cent of world languages show sounds of webwork. And, just as Hockett had predicted, collector societies had fewer laboratories.
The survey found, on average, that only 27 per cent of the biogeness looked in societies with access to processed food are in hunter-gatherers.
The researchers said that their analysis of a database of Indo-European languages showed that labiodental sounds originated between 3,000 and 6,000 years ago. There are, however, many languages around the world that do not make a lot of bone.
“In India, for example Assamese and Awadhi, following our database, there is a lack of labiodentals,” said Blasi. “I don't include a Spanish mix called Rioplatense Spanish. Languages may not have a long tradition of soft food being developed, as in Japan does not do any work.
