Evolutionary [linguists / linguistics] believe they have made a "significant breakthrough" regarding the [originality / origin] of Indo-European languages, including English and Sanskrit. The linguists say an ancient [professor / predecessor] may have been [talked / spoken] more than 8,100 years ago. The researchers are [from / of] the Max Planck Institute for Evolutionary Anthropology in Germany. Their study may [resolve / revolve] a 200-year-old dispute [surround / over] where the ancestor of English came from. One school of thought [posts / posits] English has its roots in the Pontic-Caspian Steppe [on / in] the northern shore of the Black Sea 6,000 years ago. A competing theory is that English originated from Anatolia ([much / many] of present-day Turkey) 9,000 years ago.
Indo-European languages are spoken [by / at] nearly half of the world's population. The most commonly-spoken [members / people] of this family are English, Hindi, Urdu, Spanish, Bengali, French, Russian, Portuguese and Punjabi. Each of [them / these] have over 100 million [native / nativity] speakers. More than 80 language specialists created a [hued / huge] databank of [core / caw] vocabulary from 161 Indo-European languages. The study included 52 ancient and [hysterical / historical] languages. Study co-author and Associate-Professor Russell Gray said: "Ancient [NDA / DNA] and evolutionary language analysis combine to suggest [what / that] the resolution to the 200-year-old Indo-European enigma [lies / lays] in a hybrid of the [Steppe and Anatolia] hypotheses."
