The common ancestral language of Indo-European languages - such as Hindi, English and Greek - originated about 5,500-6,500 years ago, scientists have found.

Linguists have long agreed that Indo-European languages are the modern descendants of a language family which first emerged from a common ancestor spoken thousands of years ago.

Now, a new study gives us more information on when and where it was most likely used.

Using data from over 150 languages, linguists at the University of California, Berkeley provide evidence that this ancestor language originated 5,500-6,500 years ago, on the Pontic-Caspian steppe stretching from Moldova and Ukraine to Russia and western Kazakhstan.

The research provides new support for the "steppe hypothesis" or "Kurgan hypothesis," which proposes that Indo-European languages first spread with cultural developments in animal husbandry around 4500-3500 BC.

An alternate theory proposes that they diffused much earlier, around 7500-6000 BC, in Anatolia in modern-day Turkey.

Researcher Will Chang and colleagues examined over 200 sets of words from living and dead Indo-European languages; after determining how quickly these words changed over time through statistical modelling.

They concluded that the rate of change indicated that the languages which first used these words began to diverge approximately 6,500 years ago, in accordance with the steppe hypothesis.

This is one of the first quantitatively-based academic papers in support of the steppe hypothesis, and the first to use a model with "ancestry constraints" which more directly incorporate previously discovered relationships between languages, researchers said.

In future research, methods from this study could be used to study the origins of other language families, such as Afro-Asiatic and Sino-Tibetan, researchers said.
The research appears in the journal Language
