- A new study links a specific gene and the protein variable in humans of the spoken origins of the language.
- The researchers used the editing of CRISPR genes to replace the Nova1 protein found in the mice with the type exclusively in humans, and it changed the way they covered animals when they summoned each other.
- The author of the study, Dr. Robert Darnell, hopes that the last work will lead to new ways to treat problems related to speech.
Why do humans began to speak? Scientists suggest that genetics played a major role – and they say that the development of this unique ability was a key to our survival.
A new study links a specific gene to the old assets of the spoken language, suggesting that the protein protein found in humans may help us communicate in a new way. It allowed us to participate in the participation of information, coordination of activities and the transfer of knowledge, which gives us an advantage over the children of extinct cousins such as primitive human beings and Dennisvan.
Lisa Vikac of Minnesota University, who did not participate in the research, said the new study is a “good first step to start looking at the specified genes” that may affect the development of speech and language.

What scientists learn may one day help people with speech problems.
Dr. Robert Darnell, author of the study, published on Tuesday in the magazine, said that the genetic variable researchers were looking for a variety of genes “that contributed to the emergence of the sane homo as dominant species, and it is today.” Nature Communications.

The protein – which is called NOVA1 and is known to be decisive for brain development – since the early 1990s. For the latest research, scientists at his Laboratory at the University of Rockefeller in New York used the liberation of CRISPR genes to replace the Nova1 protein found in mice with the human species exclusively to test the realistic effects of the genetic variable. To be surprised, I changed the way the animals mocked when they called for each other.
Baby mice with the human alternative are a variety differently from the normal layers when his mother came. Male mice with the alternative differ from their ordinary counterparts when they saw a female in the heat.
“They spoke differently” with the human alternative, which shows his role in speech.

This is not the first time that the gene has been linked to the words. In 2001, British scientists said they discovered the first gene associated with language and speech disorder.
It is called Foxp2, and it is referred to as the human linguistic gene. But although Foxp2 is involved in the human language, it turned out that the alternative to modern humans was not unique to us. Research later found that he was shared with primitive humans. Darnell said that the Nova1 variable in modern humans, on the other hand, is exclusively in our race.
The presence of a gene variable is not the only reason that people can speak. The ability also depends on things like anatomical features in human throat and brain areas that work together to allow people to speak and understand the language.

Darnell hopes that the last work of people will help their origins better, and also eventually leads to new ways to treat problems related to speech.
Finestack of the University of Minnesota said that it is possible that genetic results one day will allow scientists to discover, very early in life, who may need interventions in speech and language.
“This is definitely a possibility,” she said.
