- New research links the origins of the language in which a specific gene and protein variant found only in humans are spoken.
- Using CRISPR gene editing, the researchers replaced the NOVA1 protein in mice with a type that is exclusively seen in humans, changing the way animals speak when they are called out to each other.
- Dr. Robert Darnell, author of the study, hopes that recent research will lead to new ways of treating speech-related problems.
Why did humans start talking? Scientists suggest that genetics played a major role, and say that the evolution of this singular ability was key to our survival.
New research Link specific genes I propose that the ancient origins of spoken language may have helped us communicate in new ways, as seen only in humans. Speech allowed them to share information, coordinate activities, pass on knowledge, and give them an edge over extinct cousins like Neanderthals and Denisovan.
The new study is a “good first step to starting to look at a specific gene” that could affect language and language development, said Liza Feinstack of the University of Minnesota, who was not involved in the study.

What genetically diverse researchers were seeing was one of the various genes that contributed to the emergence of the disease. Homo sapiens as the dominant species“The study was published in Nature Communications on Tuesday,” said Dr. Robert Darnell, author of the study.

Darnell has been studying a protein known as NOVA1 since the early 1990s and is known to be essential for brain development. In the latest study, scientists in his lab at Rockefeller University in New York tested the seedling effects of genetic variants by replacing NOVA1 proteins in mice with human-only types. To my surprise, they changed the way animals speak when they call each other.
Baby mice with human variants became cleaner than normal littermates when their mothers arrived. Adult male mice with variants chirped in a different way than their normal counterparts when viewed in heat.
Both are environments where mice are willing to speak, and Darnell said, “And they ‘talked differently’ than the human variants.’

This is not the first time a gene has been linked to speech. In 2001, British scientists said they discovered the first gene linked to language and language disorders.
It was called FOXP2 and was called the human language gene. However, FOXP2 is involved in human language, but modern human variants have proven to be unconventional to us. Later research revealed that Share with Neanderthals. Meanwhile, the Nova1 variant of modern humans is only seen in our species, Darnell said.
The presence of genetic variants is not the only reason people can talk about it. This ability depends on things like the anatomical features of the human throat and the areas of the brain that allow people to speak and understand language.

Darnell hopes that recent works will not only help people understand their origins better, but will ultimately lead to new ways of treating speech-related issues.
Finestack of the University of Minnesota said genetic findings could one day require linguistic and linguistic intervention, very early in life.
“That’s certainly a possibility,” she said.
