Guest guest Posted May 21, 2001 Report Share Posted May 21, 2001 Genetics can be a powerful tool in answering many longstanding questions pertaining to migrations, endogamous groups,etc. Before this can be achieved, genetics must be tested in a simple case, where there is a reasonable certainty of what happened. I suggest that ( with necessary permissions ) a genetic study be made of Parsees who are known to be a self-contained endogamous group of 1500 year standing. (Next to be studied could be Kashmiri Pandits, Namboodiris of Kerala and Ayangars of Tamilnadu.) If the conclusions drawn from such a study are consistent with what is otherwise known, genetic studies can be confidently extended into areas where these will provide new and unexpected insights.

See the paper titled, "Genetic diversity in the Iberian Peninsula determined from mitochondrial sequence analysis" by CorteReal HBSM, Macaulay VA, Richards MB, Hariti G, Issad MS, CambonThomsen A, Papiha S, Bertranpetit J, Sykes BC, ANNALS OF HUMAN GENETICS, 60: 331-350, Part 4 JUL 1996. Part of their abstract reads, The timing of divergence of populations within Iberia points to a shared ancestry of all populations in the Upper Palaeolithic. Further genetic subdivision is apparent in Catalonia and Andalusia, with increased genetic diversity in the latter. Lineage diversity comparisons of Iberian populations with European (Tuscan) and North African (Algerian) populations shows the Iberian Peninsula to be more similar to other European populations, although a small number of Iberian lineages can be traced to North Africa. ------ Similar studies of more or less isolated populations are being done periodically. Studies of Icelanders and Tamil Iyers have already been cited here. It is up to the researchers in the Anthropological Survey of India and those who give them their grants, to ensure that test cases are successfully studied in India too. I would hope that a national institution that sets standards is sufficiently well-informed about such things. Vidyasankar Quote Link to comment Share on other sites More sharing options...

Check the papers listed in www.bharatavarsha.com/iyer/iyergenetics.html. This was cited earlier on this list, by Chandramouli, I think. Other studies have been done on various populations from Tamil Nadu, Andhra Pradesh, Madhya Pradesh, Uttar Pradesh, Bihar and even Manipur. I would suggest a keyword search through the database of ISI (not the Pakistani outfit, but the citation index folks in USA), and a look at back issues of journals like Human Biology, Annals of Human Genetics, Genome Research and Indian Journal of Medical Research. There is a pressing need for genetic approaches to treat various diseases, so the medical journals are a must too. For those in India, I would also suggest getting in touch with researchers from IISc, ASI and ISI (again, not the Pakistani hawks, but the statistics people in Kolkota). I see no reason to treat genetics/genomics with suspicion. A critical attitude is good, but I would put greater trust in people who know their statistics than in those who write sensationally in newspapers and magazines, and get even basic numbers and names wrong. Re: significance of the third decimal in autosome correlations, no clear progress yet. If someone else sees a good reference article or book, I would greatly appreciate it if they were to share the information with me.
