Researchers Link Gene to Emergence of Spoken Language
A new study links a particular gene to the ancient origins of spoken language, proposing that a protein variant found only in humans might have helped us communicate in a novel way.
Why did humans start speaking? Scientists suggest genetics played a big role – and they say the evolution of this singular ability was key to our survival.
A new study links a particular gene to the ancient origins of spoken language, proposing that a protein variant found only in humans might have helped us communicate in a novel way. Speech allowed us to share information, coordinate activities, and pass down knowledge, giving us an edge over extinct cousins like Neanderthals and Denisovans.
The new study is "a good first step to start looking at the specific genes" that might affect speech and language development, said Liza Finestack at the University of Minnesota, who was not involved with the research.
What scientists learn may someday even help people with speech problems.
The genetic variant researchers were looking at was one of a variety of genes "that contributed to the emergence of Homo sapiens as the dominant species, which we are today" said Dr. Robert Darnell, an author of the study published Tuesday in the journal Nature Communications.
