Recent Advances in South Indian Archaeology – The 2nd International Symposium in memory of Iravatham Mahadevan – Dravidian – known and unknown (2)

10-03-2023 – Friday – Continuance of paper reading session: After the Minister’s visit, Appasamy Murugaiyan delved upon the nuances of syntax, grammar, linguistics, prosody, etc. With Sangam literature, he was explaining such linguistic traces, glosses and interpretations. Next, Pitchappan while presenting his views on the “Evolution of Dravidian – known and unknown” mainly repeating already published matter “out of Africa” hypothesis and theory and maintaining his stand that Dravidians came from Africa. He also claimed that “Dravidian is inclusive of language, culture and gene code”  Men originated from Africa and by 60,000 YBP spread out from Africa, unidirectionally, the Y-chromosome was spreading. Polymorphism – first man appeared in Veerumandi, near Madura, in Tamilnadu. In other words, the African primate, hominid came here to settle and evolve into a Dravidian. All the Sangam tribes Kadan, Kurumban etc., of all categories came from Africa. He undertook the 1-million-dollar project in 20006-2015 on the “Genography” project 10,000 Indian samples taken and research conducted to arrive at such results. Three unidirectional migrations represent Dravidian at different periods.  Neolithic people came from outside. How the migrated were mixed, languages cannot be determined. Root words spread occurred by 15,000 YBP. Murugan is considered as “Tamil god” Neolithic god, but, it was known in Gandhara before Sangam period. Caste system in Sangam period is noted with male domination. With chromosomes and their connection with the language speaking people are pointed out. Yet, nothing can be said definitely. Even asper the dating c.6th cent.BCE does not help this chronology.

He was arguing that “Dravidian” evolved at different periods………………………..

For the questions asked, he maintained that humanity originated only from Africa: He claimed that he worked with the “Genographic project” and the DNA results show that humanity originated in Africa and spread to other continents. Was there any origin of man from South India and such questions were asked, but, he maintained that that humanity originated in Africa and spread to other continents. This is studied after 2500-3500 YBP, thus, much of miscegenation could have taken place. It is believed that man originated from Africa and spread to other parts of the world. He sticks to the theory, as obviously, he has been working for the project. Europeans do not accept that they originated from Europe and therefore, if they originated from India, then, evidences have to be produced.

He was stressing how humanity originated from Africa and spread……..

Tamil monkey or Dravidian monkey?: TH CM was reacting euphemistically, “Our minds become energized and happy when we say Tamil Nadu Tirunal. Nevertheless, some people tease us by saying the first monkey born in the world was the Tamil monkey. However, we are not concerned about that. Whatever we say, it is scientifically based,” he said[1]. TH CM was telling that “the first monkey on the earth was a “Tamil” monkey and such claim is scientifically based”[2], but, he (Pitchappan) says, it was a Dravidian monkey. Thus, the Tamil-Dravidian wrangle has been there linguistically and scientifically among the DNA-scientists and the Dravidian experts. As the Europeans try to have their own “Neanderthal,” Dravidians want their “Tamil counterpart.” Therefore, the hypothesized monogenetic or multi-genetic origin of hominid, homoerectus, monkey, ape, chimpanzee etc., would continue with scientific research.

Aryan invasion and Dravidan invasion or migration?: Indian history has been with the Aryan race, invasion and then, migration (through invasion and various means) hypotheses and theories. Thus, whenever the word “Arya, Aryan, Ariyan”, etc., was read, Indians think about some nomadic race coming from Central Asia entering India through the northwest and defeating the Dravidian people of the area, particularly, the Indus Valley. Though, initially, “Dravida, Dravidians, Dravidar” were not thought of, after the advent of Caldwell, such hypotheses and theories have also become popular. Thus, the Aryan-Dravidian hypotheses and theories have been part and parcel of the history books taught for the last 100 hears. As for as the Tamilnadu is concerned, such hypotheses and theories have become not only history, but also, art, archaeology, dance, drama, cinema etc., at one side and politics, political party, political ideology and so on., at the other side. Now, if the DNA research claims that Dravidian also came from Africa, then, what exactly happened in history?

Rakhigarhi or Africa? – how the archaeologists decide?: According to recent reports, with the latest works (archaeological and genetic) in and around Rakhigarhi, Sinauli, etc, the Aryan invasion hypothesis surely died its deserved death. But another theory became prevalent that said that Homo sapiens first emerged in Africa and by around some 70-50,000 years ago, a small group (possibly as few as 150 to 1,000 people), crossed the Red Sea. They travelled along the coastal route around the coast of Arabia and Persia until reaching India. This proposition was popularly called the Post Toba Theory. As per the existing models, the modern human dispersals are primarily based on lithic assemblages, a few fossils remains and genetics. According to the most popular model (MIS 5), the modern humans left Africa around 120,000 years ago and colonised the rest of the whole world by 40,000 years ago. But the recent studies tell us that as per the fossil evidence from Apidima Cave in Greece (Harvati et al., 2019[3]) and Misiliya cave in Israel[4] (Hershkovitz et al., 2018) the modern human existence outside Africa goes older than 210,000 years ago.

Pre-Toba models and other claims about the origin: However, these findings do not yet ascertain the dispersal to South Asia earlier than 120,000 years ago. The scholars of the field attribute the Middle Palaeolithic technologies’ presence in India and the rest of South Asia to the modern humans that arrived from Africa between 120,000 and 70,000 years ago (Petraglia et al., 2007). This conclusion came from a very interesting finding from the 74,000-year-old Toba Tuff deposits at the Jwalapuram site. These were the Middle Palaeolithic artefacts and resembled almost the African Middle Stone Age artefacts (Petraglia et al., 2007; Haslam et al., 2012). And that is how the Pre-Toba model (Petraglia et al., 2007) became popular to explain the initial modern human colonisation of India.

Toba, pre-Toba etc.,: Next the luminescence age testing was further carried out in various sites, and they further reinforced the pre-Toba model. The Middle Palaeolithic assemblages from Katoti in Rajasthan and Sandhav in Kutch, were found to be around 96 ± 13 and 114 ±12 thousand years old respectively (Blinkhorn et al., 2013; Blinkhorn et al., 2019). Even the research from a site in the middle of the Son Valley called Dhaba showed out middle Palaeolithic assemblages dating to around 80,000 years, thereby bringing more buttresses for pre-Toba model (Clarkson et al., 2020). These studies utilising reliable chronometric ages of Middle Palaeolithic assemblages ranging from 120 to 40 thousand years ago, hint to the notion that the South Asian Middle Palaeolithic expertise was familiarised by the modern humans as a part of the Eurasian colonisation after having branched out of Africa. Then we have the studies which show that the youngest age for the Late Acheulean assemblages from Patpara going to 137 ± 10 thousand years ago and 131 ± 9 thousand years ago in Bamburi respectively (Haslam et al., 2011). These studies corroborate the notion about the existence of archaic hominins just before the appearance of modern humans in South Asia, as understood by the Out of Africa theory.

Why not Attirampakkam?: But there is something beyond those studies which somehow has not been taken into academic consideration. At Attirampakkam Middle Palaeolithic assemblages were found which dated to around 385 thousand years ago (Akhilesh et al., 2018). As per the latest studies, it has been understood that Middle Palaeolithic technology in South Asia goes way older than academic consensus on the footprint of modern humans outside Africa (Devara et al., 2022). But just the presence of Middle Palaeolithic assemblages is not enough to decide for the existence of Homo sapiens in India a lot before the alleged dispersal around 75,000 years ago from Africa and at least simultaneous existence.

Africa or Europe?: Stringer, Chris, and Lucile Crété conclude carefully[5], “Recent progress in the recovery of environmental DNA from cave sediments promises to revolutionize our under­standing of population relationships on the ground as H. sapiens and H. neanderthalensis groups interacted with each other. Few European sites in the time period between 40–60 ka contain human fossils, but many more of them could contain traces of human presence in the form of mitochon­drial and nuclear genomic material. Research so far dem­onstrates that sediment DNA can identify humans at the species and individual levels, and this could potentially map the co-existence of different populations, their sex, their kinship relations, and the extent of intermixture be­tween the different populations (Vernot et al. 2021; Zavala et al. 2021). Such breakthroughs could not have been an­ticipated even a few years ago, and no doubt there will be many more surprises to come. There is still much to learn about the ancient encounters that we have discussed in this paper, which left an indelible genetic mark on humanity today, and which makes their study so intriguing”.

  1. Ancient DNA Lab opened in MKU; helps in genetic studies and data analysis for Archaeology Department’s excavations in Tamil Nadu

    By Shastry V MalladyNov 17, 2022, 19:27 Pm

    https://www.lotustimes.org/2022/11/17/ancient-dna-lab-opened-in-mku-helps-in-genetic-studies-and-data-analysis-for-archaeology-departments-excavations-in-tamil-nadu/

    MADURAI: Genetic studies in Tamil Nadu will get a major boost thanks to the Ancient DNA Laboratory which was inaugurated and declared open in Madurai Kamaraj University (MKU) in Madurai today- on November 17th 2022.

    Mr.P.T.R.Palanivel Thiagarajan, Finance and Human Resources Minister, Government of Tamil Nadu, had inaugurated the DNA lab and also BSL-3 laboratory, in the presence of Prof.J.Kumar, Vice-Chancellor, Madurai Kamaraj University, Prof.M.Sivakumar, university Registrar and Prof.G.Kumaresan, Head, Department of Genetics, MKU and others.

    The Department of Genetics of MKU with RUSA support has established an ancient DNA lab, with the objective to generate and analyze ancient DNA data from archaeological excavations of Tamil Nadu. This lab has been set up by following the models at University of Chicago and Birbal Sahni Institute of Palaeosciences, Lucknow.

    This will be useful to provide genetic / DNA and other biological evidence for the materials excavated by the Archaeology Department of Government of Tamil Nadu. The cost of the ancient DNA lab facility is coming to Rs.3.3. crores including the equipment installed.

    The ancient DNA program of MKU is progressing in 9 directions for the past one year including ancient human DNA analysis, ancient animal analysis, ancient plant DNA analysis, microbiome analysis etc.

    A press release received from the MKU here yesterday had informed that the university is primarily working in collaboration with Department of Archaeology of Government of Tamil Nadu. The skeletal samples from Konthagai, Sivagalai, Kodumanal, Mayildumparai and Adhichanallur are analyzed. Recently, the ASI excavated samples are also being investigated.

    The press release added that MKU collborates with Prof.David Reich from Department of Genetics-Harvard Medical School, USA. Prof.Kumaresan, Head of Department of Genetics, School of Biological Sciences-MKU, is the coordinator of the Ancient DNA Team at MKU and here a clear expected outcome is there to generate ancient genomics data from the biomaterials of different excavations from Tamil Nadu, studies of ancient human migration, the molecular analysis of practices in Tamil Nadu in ancient years etc.

  2. Times of India,  Rs 3cr ‘ancient DNA lab’ to studyexcavated artefacts in TN: Minister, M T Saju / TNN / Updated: Aug 25, 2020, 10:57 IST

    https://timesofindia.indiatimes.com/city/chennai/rs-3cr-ancient-dna-lab-to-studyexcavated-artefacts-in-tn-min/articleshow/77730097.cms

    Chennai: The antiquities unearthed during the ongoing archaeological excavations at places like Keeladi, Adichchanallur, Sivagalai and Kodumanal across the state will be analyzed using modern scientific methods in reputed laboratories and institutions, said minister for Tamil language, culture and archaeology K Pandirajan on Monday.

    “To supplement the ongoing archaeological excavations in Tamil Nadu, Madurai Kamaraj University has taken necessary steps to establish an ‘ancient DNA lab’ at a cost of Rs 3 crore.

    … We normally depend on foreign laboratories for testing and it consumes a lot of time and energy. New initiatives like this will help get the results faster,” the minister said, while releasing “Ongoing archaeological excavations in Tamil Nadu: A status report (July 2020).”

    The report, which includes graphs, fact-files and figures, shows the systematic archaeological explorations and excavations conducted across the state since the sixth season of systematic archaeological excavation was inaugurated by chief minister Edappadi K Palaniswami on February 19.

    Having recognized the valuable contribution of specialized disciplines for a deeper analysis of archaeological findings, the state department of archaeology is collaborating with experts from such fields as archaeo-botany, molecular biology, population genetics, prehistoric archaeology, environmental archaeology and linguistic archaeology. “The department has taken up a major initiative in adopting various technologies like ground penetrating radar (GPR) survey, magnetometer survey, unmanned aerial vehicle (UAV) survey to identify the ideal spot for carrying out the explorations and excavations with the help of reputed institutions in India,” he said.

    On the trenches and quadrants laid as part of the excavations at Keeladi, Adichchanallur, Sivagalai and Kodumanal, Pandirajan said 76 trenches and 168 quadrants had been opened till the end of July. “We have collected 128 carbon samples from these sites, the highest being 97 from Keeladi and its clusters,” he said. It was to study the civilisation that flourished along the Vaigai river in detail that excavations have been taken up in the clusters of Keeladi such as Kondagai, Manalur and Agaram, he said. “The available information provides a clear idea of a habitation-industrial-burial site here.” Asked why the department was not taking any action to preserve the idols that had been returned from foreign countries, Pandiarajan said the courts concerned and the police department had to decide where these idols should go. “We are ready to take care of them. But it’s the court that should decide whether the idols should go to the temple or museum,” he said.

  3. Deccan Herald, Harvard team helps Tamil Nadu lab with ancient DNA extraction and analysis, ETB Sivapriyan DHNS Published 16 February 2023, 22:51 IST; Last Updated: 17 February 2023, 09:38 IST DHNS

    https://www.deccanherald.com/india/harvard-team-helps-tamil-nadu-lab-with-ancient-dna-extraction-and-analysis-1191996.html

    Tamil Nadu’s first Ancient DNA Lab at the Madurai Kamaraj University has opened its doors for a team from the world-renowned David Reich Lab to assist it in extracting DNA from 30 human samples collected from burial urns unearthed during excavations with “minimal damage” as part of the efforts to provide scientific evidence to archaeological findings.

    The team led by Kendra Sirak, Senior Staff Scientist at David Reich Lab of the prestigious Harvard Medical School, US, is camping in the temple town of Madurai since February 13 to help the new lab analyse the samples collected from Konthagai, Sivagalai, Adichanallur, Mayiladumparai, and Kodumanal.

     Konthagai is the burial site of Keeladi, the urban habitation site that is believed to have existed between 800 BCE to 300 CE as per a recent report submitted by Archaeological Survey of India (ASI) on the first two phases of the digging between 2014 and 2016. The new date derived by the ASI pushes the Sangam Era behind by another 500 years than it was earlier thought to be.

    The lab, which was inaugurated in November 2022, has begun preliminary work on conducting ancient DNA analysis on human, animal, and plant samples collected by the Tamil Nadu State Department of Archaeology (TNSDA) and ASI.

    “We have begun the dry run. The samples are expectedly contaminated because they remained buried deep for centuries together. We are now being assisted by the Harvard team in extracting DNA from the human samples with minimal damage,” Professor G Kumaresan, Head, Department of Genetics, School of Biological Sciences, MKU, told DH.

    “The team is helping us with the techniques they have successfully followed so far,” Kumaresan added. Sirak, who has so far analysed 500 DNA samples, is an expert in extracting DNA without disturbing the skull much and lessons from her will only help those at the MKU lab learn the tricks of the trade.

    DNA is extracted mainly from teeth and petrous bones of the human samples which is used as the primary input. “DNA is generally extracted Calculus bone and from the root of the teeth. The extracted portion is then processed and computationally analysed. We will then compare the data of ancient DNA with global data to understand migration (of people) and the linkages with global populations,” Kumaresan added.

    Sirak said her team was excited to collaborate with MKU team to study DNA from people who lived in Tamil Nadu long ago. “We will combine our expertise in hopes to generate authentic ancient DNA sequences that will help us to learn more about this very important part of India,” she told DH.

    The results of the DNA analysis generated by the MKU lab will be cross-checked by the Harvard team to ensure that the findings are right and questions are not raised over them since the samples are contaminated with bacterial DNA.

    The results will then be compared with thousands of ancient and modern human genomes across the globe to explain in detail the ancient human migration and will be corroborated with Sangam Literature wherever possible.

    Apart from ancient DNA, the MKU team is also exploring the proteins from skeletal remains and organic molecules from the potsherds of the offering pots. Some of the molecules retrieved so far includes Floxuridine (rice), Orotic Acid (milk), Myristic Acid (myristica), Ricinoleic Acid (castor) and cholesterol (animal fats).

    The MKU lab has already sequenced about 1500 millions of DNA fragments from 20 samples of humans, animals, and plants. The DNA collected from the samples will help understand the agricultural and trade practices, while the organic molecular analysis would reveal the agricultural, cultural, and social practices in Tamil Nadu during 500 BC – 2500 BC.

    The retrieval of rice is significant as pollen analyses of samples from the first phases of excavations in Keeladi found that excess production of rice contributed to the growth of the urban city while fertile land played “an active role” for the evolution of the habitation. The excess production of rice prompted the settlers to set sail in the seas to far-away land that are chronicled in several literature, the ASI report, which is yet to be made public, says.
