Nature: A new study finds evidence that farmers in Turkey were key to the spread of Indo-European languages 9,000 years ago. Russell Gray and Quentin Atkinson, of the University of Auckland in New Zealand have been studying the mutations that languages go through as they develop and grow. They used a list of 200 words to study 87 cultures and languages to see how they developed. Their conclusion is that when farming practices spread from Anatolia, in today's Turkey, they took with them the language.

The finding by the two researchers is expected to spark controversy since many believe that the language was carried out of central Asia by Kurgan horsemen, rather than farmers. To read the complete story, visit the website.
