Phylogeny of R1a and Indo-European languages




Phylogeny of R1a and Indo-European languages

Ancient DNA testing has confirmed the presence of haplogroup R1a-M417 in samples  from Tocharian mummies (2000 BCE) in Northwest China
According to Underhill (2014), the downstream R1a-M417 subclade diversified into Z282 and Z93 circa 5,800 years ago. Even though R1a occurs as the most frequent Y-chromosome haplogroup among populations speaking a wide variety of languages such as Slavic, Indo-Iranian, Dravidian, Turkic and Finno-Ugric, the question of the origins of R1a1a is relevant to the ongoing debate concerning the urheimat of the Proto-Indo-European people, and may also be relevant to the origins of the Indus Valley Civilisation. R1a shows a strong correlation with Indo-European languages of Southern and Western Asia and Central and Eastern Europe, being most prevalent in Eastern Europe, West Asia, South Asia and Central Asia. In Europe, Z282 is prevalent particularly while in Asia Z93 dominates. The connection between Y-DNA R-M17 and the spread of Indo-European languages was first noted by T. Zerjal and colleagues in 1999.
