For thousands of years, spoken language has set humans apart from all other species. The ability to convey complex ideas, describe experiences, and communicate across generations has played a crucial role in shaping civilization.

Now researchers from The Rockefeller University have unearthed intriguing genetic evidence: a protein variant found only in humans that may have helped shape the emergence of spoken language.

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,
