The Indo-European languages are a family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by Ethnologue, with over two-thirds (313) of them belonging to the Indo-Iranian branch. The most widely spoken Indo-European languages by native speakers are Spanish, English, Hindi, Portuguese, Bengali, Russian, and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an Indo-European language, by far the most of any language family.
The Indo-European family includes most of the modern languages of Europe, and parts of Western, Central and South Asia. It was also predominant in ancient Anatolia (present-day Turkey), and the ancient Tarim Basin (present-day Northwest China) and most of Central Asia until the medieval Turkic migrations and Mongol invasions. With written evidence appearing since the Bronze Age in the form of the Anatolian languages and Mycenaean Greek, the Indo-European family is significant to the field of historical linguistics as possessing the second-longest recorded history, after the Afroasiatic family.
All Indo-European languages are descendants of a single prehistoric language, reconstructed as Proto-Indo-European, spoken sometime in the Neolithic era. Although no written records remain, much of the culture and religion of the Proto-Indo-European people can also be reconstructed based on their daughter cultures traditionally and continuing to inhabit most of Europe and South Asia, areas to where the Proto-Indo-Europeans migrated from their original homeland. Several disputed proposals link Indo-European to other major language families.
