The Indo-European question

We know that the languages of the Indo-European language family are all related, but determining the exact spread of these languages across Europe and Asia has been difficult to do. Marija Gimbutas argues that the Indo-European people originated in the steppes of Russia and Central Asia, and that these people migrated outward, dominating the cultures they encountered. Other scholars, such as Colin Renfrew, argue that the Indo-Europeans migrated out of Anatolia slowly, intermingling with new cultures. These differing viewpoints each use archaeological and linguistic evidence to supplement their arguments. However, they also show that there is still much to discover about this fascinating topic.
