Scientists link gene to emergence of spoken language
A new study links a particular gene and a protein variant found only in humans to the origins of spoken language.Researchers used CRISPR gene editing to replace the NOVA1 protein found in mice with the type exclusively found in humans, and it changed the way the animals vocalized when they called out to each other.The author of the study, Dr. Robert Darnell, hopes the recent work could lead to new ways to treat speech-related problems.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 may have helped us communicate in a novel way. Speech allowed us to s...
