Evolutionary linguists believe they have made a "
breakthrough" regarding the
of Indo-European languages, including English and Sanskrit. The linguists say an
predecessor may have been spoken more than 8,100 years
. The researchers are from the Max Planck Institute for Evolutionary Anthropology in Germany. Their
may resolve a 200-year-old
over where the ancestor of English came from. One school of thought posits English has its
in the Pontic-Caspian Steppe on the northern
of the Black Sea 6,000 years ago. A competing
is that English originated from Anatolia (much of
-day Turkey) 9,000 years ago.
