Yup. Linguists have 'pinpointed' the origin of all the Indo-European languages to Anatolia, the mother tongue, so to speak.
However, the Basque language is not related in any way to the Indo-European languages. (Which still puzzles me.)
It confuses me too, are the Basque people even real Europeans?
Neither are the languages spoken by the Finns,the Hungarians,and the Mari. They are related to each other,but are also not related to the Basque language.
BTW,the Mari are the native people of a section of modern day Russia called the "Mari Republic". For lack of a better description,they are a tribe of "Russia's Indians."It's about 600 KM's from Moscow,and "Yoshkar-Ola" is the capital town. I've been there and visited the Mari National Museum,and it is a fascinating place. You would swear you are looking at Cherokee artifacts. The Mari even looked like Cherokees.
I think it is really fascinating that three seperate cultures that far apart could share a language base that is in no way related to any of the languages that surround them.
