New paper (behind paywall) Neolithic phylogenetic continuity inferred from complete mitochondrial DNA sequences in a tribal population of Southern India, by Sylvester et al. Genetica (2018).
This paper used a complete mtDNA genome study of 113 unrelated individuals from the Melakudiya tribal population, a Dravidian speaking tribe from the Kodagu district of Karnataka, Southern India.
Some interesting excerpts (emphasis mine):
Autosomal genetic evidence indicates that most of the ethnolinguistic groups in India have descended from a mixture of two divergent ancestral populations: Ancestral North Indians (ANI) related to People of West Eurasia, the Caucasus, Central Asia and the Middle

Open access A Bayesian phylogenetic study of the Dravidian language family, by Kolipakam et al. (including Bouckaert and Gray), Royal Society Open Science (2018).
Abstract (emphasis mine):
The Dravidian language family consists of about 80 varieties (Hammarström H. 2016 Glottolog 2.7) spoken by 220 million people across southern and central India and surrounding countries (Steever SB. 1998 In The Dravidian languages (ed. SB Steever), pp. 1–39: 1). Neither the geographical origin of the Dravidian language homeland nor its exact dispersal through time are known. The history of these languages is crucial for understanding prehistory in Eurasia, because despite their

The Proto-Indo-European Urheimat
Not long ago, the Proto-Indo-European language Urheimat problem used to be cyclic in nature: linguistic and archaeological publications appeared supporting a Copper Age migration from the steppe proposed by Marija Gimbutas, or a Neolithic expansion from Anatolia (or Armenia) proposed by Colin Renfrew, and back again.
I have always supported the simpler, more recent Chalcolithic migration of Late Indo-Europeans from the Pontic-Caspian steppe over an older Neolithic expansion from Anatolia with agriculture. The latter model implied a complex cultural diffusion over a greater span of time than is warranted by linguistic guesstimates, understood as the … Read the rest “The Aryan migration debate, the Out of India models, and the modern “indigenous Indo-Aryan” sectarianism”
