The gene is called Nova1, and in our species is incredibly unique. While almost all other mammals have the same variant of Nova1 in its genetic code, one change in the amino acid in the human version.
This one, subtle adjustment may have played a key role in the origin of the speech language and the expansion and survival of Homo Sapiens, according to researchers from the University of Rockefeller and the Cold Spring Harbor University in New York.
Not even Neanderthals and Denys have the same variant, which means he had to evolve in the last few hundred thousand years, after our species separated from these extinct relatives.
Another suggested ‘language genes’, such as FOXP2, which also make mice a different whine, are in the DNA Neanderthal. So, although they probably also contributed to the origin of the human language, they may not be responsible for our newer evolutionary success.
It is not clear what the language skills of our extinct relatives used to be, but this recent change has shown to be very successful in the human genome.
In more than 650,000 sequences of human DNA, researchers found only six anonymous people who did not have a modern variant of Nova1. Nothing knows about these people.
When it comes to the origin of a complex human language, Nova1 is a “new kid,” Genetic Wolfgang Enard who worked on the Foxp2 Geno for Carl Zimmer for the New York Times.
“This gene is a part of a comprehensive evolutionary change in early modern people and hints at the potentially ancient spoken language origin,” says Robert Darnell from the University of Rockefeller, who studies the Gene and the Intellent Function and the Intellectual Function from the early 1990s.
“Nova1 can be a credible human ‘language gene’, although only one of the many genetic changes specific to man is certainly.”
