- A new study combines a special gene and a protein version that is found only for the origin of the language spoken in humans.
- Researchers used crispr gene editing, which changed the Nova1 protein found in mice, especially with the type found found in humans, and it changed animals in an outspoken manner when he called each other.
- The author of the study, Dr. Robert Darnell hopes that recent work may have new ways to treat speech-related problems.
Why did humans start speaking? Scientists suggest that genetics played a major role – and they say that the development of this unique ability was important for our existence.
A new study connects a particular gene to the ancient origin of the language spoken, proposing that only a protein version found in humans may help us communicate with a novel manner. The speech allowed us to share information, coordinate activities and pass knowledge, leading us an edge over extinct cousin such as Neanderthal and Denisovans.
The new study “is a good first step to start looking at specific genes” which can affect speech and language development, said Lisa Finstec at Minnesota University, which were not involved with research.

Genetic variants researchers were noticing that one of the various types of genes was “who contributed to the emergence of Homo Sepians, which we are today,” Dr. of the study published on Tuesday in Journal Nature Communications, Dr. Robert Darnell said.

Darnell is studying protein – called Nova 1 and is considered important for brain development – from the beginning of the 1990s. For the latest research, scientists at their laboratory at Rockfeller University in New York used crispr gene editing to change the Nova 1 protein found in mice, especially to test the effects of the real -life of genetic variants. For their surprise, it changed the way animals call out from each other.
When her mother came around her mother, baby rats with a human version shouted differently than normal litmets. When they saw a woman in the summer, adult male rats with variants used to chirping differently than their normal counterparts.
Both are settings where mice are motivated to speak, Darnell said, “and they speak differently” with the human version, reflecting their role in speech.

This is not the first time a gene has been linked to a speech. In 2001, British scientists said they had discovered the first gene tied with a language and speech disorder.
Called Foxp2, it was referred to as the human language genes. But although the foxp2 is included in the human language, it turns out that the version in modern humans was not unique to us. Later research found that it was shared with Neanderthal. On the other hand, Nova 1 version in modern humans, especially found in our species, said Darnell.
The presence of a gene version is not the only reason people can speak. The capacity also depends on human throat physical characteristics and things such as brain areas that work together to allow people to speak and understand language.

Darnell hopes that recent work not only helps people understand their origin better, but also creates new ways to treat speech related problems.
The University of Minnesota said that it is more likely that genetic conclusions may allow scientists to find out this day, very early in life, which may require speech and language intervention.
“This is definitely a possibility,” he said.
