Dr. Niraj Rai

I'm an Archaeogeneticist working Birbal Sahni Institute of Palaeosciences, Lucknow, India. I started my journey in the field of ancient DNA (aDNA) while working on relics excavated on St. Augustine Church in Goa during my Ph.D at Centre for Cellular and Molecular Biology, India.

The Aryan Invasion Debate

In this podcast, Kushal speaks with Koenraad Elst and Niraj Rai about the recent updates around the Aryan Invasion Theory. In light of the recent findings of the Southern Arc papers can we still conclude that South Russia is the Proto-Indo-European homeland?

Day 3 S3 - Revisiting AIT, Indian Science, Chronology | Nilesh O, Niraj Rai, Abhijit C, Shiv S, SD

India's ancient history is marred by distortions and perversions like Aryan Invasion Theory, disappearing India's Science and corrupting its chronology.

Aryan Invasion Theory: Prove AIT, Win 2 Cr | David Frawley, Niraj Rai, Abhijit, Aravind, Sanjay

Jaipur Dialogues 2019 | Session on much talked about Aryan Invasion Theory On Stage - 1. David Frawley (Pandit Vamdev Shastri) 2. Abhijit Chavda 3. Shiv Shastry 4. Niraj Rai 5. Arvindan Neelakandan 6. Sanjay Dixit #AryanInvastionTheory #JaipurDialogues2019 #Win2Cr ------------------------------------------------------ Twitter Handle - @jaipurdialogues ------------------------------------------------------ The distinguished panel discusses the origins of the Aryan Invasion Theory, its propagation, and how it has been totally discredited. Aravindan Neelakandan gives the insights into the Biblical racist narrative that was used by the Church through the linguists to supplant the original linguist fascination for Sanskrit and the Out of India Theory. The best part of this Theory is that it was never scientifically validated, yet Church operatives like Robert Caldwell and Verrier Elwin used it to sow the seeds of division in the form of Dravidianist and Evangelical politics in the South and North-East of India. Ever since the discovery of Indus Valley sites of Harappa and Mohan-jo-Daro, AIT has been on the defensive, first trying to transform itself into Aryan Migration Theory, and then just keeping up the propaganda through Left historians. After the archaeological excavations of Lothal and Dvaraka, the chronology of AIT became totally untenable, and the Biblical chronology was demolished in the West itself. AIT found its last defenders among geneticists, but as Dr. Niraj Rai would tell us in this video, even that fig leaf has crumbled. Do watch this informative and serious discussion that covers almost every aspect of the issue.

Revisiting the genetic histories of our past | Dr. Niraj Rai | #SangamTalks

Reconstructions of the past effective population size strongly suggest that South Asia has been populated almost since the Early Upper Palaeolithic. One of the probable explanations of this pattern relates to the fact that South Asia was among the first geographic regions to be peopled by modern humans after their African exodus. Today, various ethnic groups of South Asia comprise tribes, castes, & populations identifying themselves by different religions, being largely endogamous & hence revealing complex, multilayer genetic differentiation. From such a complex structure, several questions have stood out from our & other research groups analyses that could not be addressed a few years ago but can be now using the latest technology & resolution. The novelty of the approaches rely largely, though not solely, on extensive high-coverage sequencing of specifically targeted modern & ancient samples, autosomal SNP genotyping of specific populations, extensive Y chromosome resequencing of selected population groups (Tribal & caste populations from different geographical area) & statistical analysis of the results in the context of human genomic variation worldwide. Speaker: Niraj Rai (NR) is a molecular biologist by training and specialized in ancient DNA analysis and generating next-generation sequencing data to study genetic histories of the human population. He is an expert researcher in retrieving and analysing ancient DNA from the challenging arid and tropical environments of South and South East Asia. He founded and runs the only successful aDNA lab in India, and has a rapidly expanding portfolio of research into the history, diversity and evolution of ancient and modern Indian populations, as well as work on animal and pathogen genetics. Niraj is closely working with Anthropologists and Archaeologists of South and South East Asia and established collaboration with over 40 institutions across the Indian sub-continent. He has catalogued and collected archaeological samples that exist in collections from all over the country. His recent findings on ancient DNA published in Science, Cell & Nature Communications was shared and discussed heavily on international scientific forum. His paper, as a corresponding author entitled- “An Ancient Harappan Genome Lacks Ancestry from Steppe Pastoralists or Iranian Farmers,” published in 2019 Picked up heavily by Archaeologists and Biological Anthropologists. His research article published in nature communication in 2019 entitled- “Ancient DNA from the skeletons of Roopkund lake reveals Mediterranean migrants in India” solved the genetic identity of human skeletons from a mysterious high-altitude Himalayan Lake. His co-authored research article in journal Science (2019) entitled- “The formation of human populations in South and Central Asia” was one of the milestone papers on Central and South Asian ancestry. His another first authored paper in Scientific Reports published in 2020 entitled- “Ancient mtDNA from the extinct Indian Cheetah supports unexpectedly deep divergence from African cheetahs” has enormous implication in conservation and reintroduction of extinct Cheetah species in India.

An Ancient Harappan Genome Lacks Ancestry from Steppe Pastoralists or Iranian Farmers

We report an ancient genome from the Indus Valley Civilization (IVC). The individual we sequenced fits as a mixture of people related to ancient Iranians (the largest component) and Southeast Asian hunter-gatherers, a unique profile that matches ancient DNA from 11 genetic outliers from sites in Iran and Turkmenistan in cultural communication with the IVC. These individuals had little if any Steppe pastoralist-derived ancestry, showing that it was not ubiquitous in northwest South Asia during the IVC as it is today. The Iranian-related ancestry in the IVC derives from a lineage leading to early Iranian farmers, herders, and hunter-gatherers before their ancestors separated, contradicting the hypothesis that the shared ancestry between early Iranians and South Asians reflects a large-scale spread of western Iranian farmers east. Instead, sampled ancient genomes from the Iranian plateau and IVC descend from different groups of hunter-gatherers who began farming without being connected by substantial movement of people.
