Listening for Stone-Age Voices: How Humans Learned to Talk

A BBC feature explains how scientists infer what early humans sounded like by examining fossil skulls, vocal‑tract anatomy and brain development, outlining two main theories of language origins (sudden symbolic thought vs gradual evolution) and tracing a timeline from primate vocal capacity 27 million years ago to Cro-Magnon speech ~30,000 years ago, suggesting Neanderthals could have spoken and that Homo sapiens eventually developed a full language-ready system, ending with a note on today’s thousands of languages and their fragility.
