The origin of language

What makes this fascinating

• Only humans have it — No other species has open-ended, grammatical language — why only us?

• No fossils of speech — Language leaves no direct trace, so its emergence has to be inferred indirectly.

• Gradual or a sudden leap? — Did language evolve step by step, or arrive with a single cognitive change? Hotly debated.

Frequently asked questions

How did human language originate?

Unknown. Language leaves no fossils, so whether humans developed syntax and symbolic speech gradually or in a leap — and when — is debated and may never be fully settled.

Why do only humans have language?

No other species has anything with the open-ended, recursive grammar of human language. What cognitive or genetic change enabled it is unresolved.

When did language evolve?

Estimates range widely, from hundreds of thousands of years ago to a more recent emergence, because direct evidence is so scarce.
