LONDON: The largest ever DNA survey of Indian heritage has revealed that the population of India was founded on just two ancient groups that are as genetically distinct from each other as they are from other Asians.
The findings of the study, conducted by a group of top international geneticists, have strong implications for health and medicine, and reveal important new information on caste in India.
The study shows that most Indian populations are genetic admixtures of two ancient but genetically divergent groups, which each contributed around 40-60 percent of the DNA to most present-day Indians, Nature magazine reported Wednesday.
One ancestral lineage - genetically similar to Middle Eastern, Central Asian and European populations - was higher in upper-caste individuals and speakers of Indo-European languages such as Hindi, the researchers found.
The other lineage was not close to any group outside the Indian subcontinent, and was most common in people indigenous to the Andaman islands, says the study conducted by a team led by David Reich of the Broad Institute in Cambridge, Massachusetts, and Lalji Singh of the Centre for Cellular and Molecular Biology in Hyderabad, India.
Nature said that although India makes up around one-sixth of the world's population, it has been "sorely under-represented" in genome-wide studies of human genetic variation.
The Indian Genome Variation database, launched in 2003 to fill the gap, has so far studied only 420 DNA-letter differences, called single nucleotide polymorphisms (SNPs), in 75 genes.
In sharp contrast, the study reported by Nature has probed more than 560,000 SNPs across the genomes of 132 Indian individuals from 25 diverse ethnic and tribal groups dotted all over India.
The researchers also found that Indian populations were much more highly subdivided than European populations. But whereas European ancestry is mostly carved up by geography, Indian segregation was driven largely by caste.
"There are populations that have lived in the same town and same village for thousands of years without exchanging genes," said Reich.
The authors of the study said the new genetic evidence refutes the claim that the Indian caste structure was a modern invention of British colonialism.
"This idea that caste is thousands of years old is a big deal," said Nicole Boivin, an Oxford University archaeologist.
"To say that endogamy (the practice of marrying within a caste, community or tribe) goes back so far, and that genetics shows it, is going to be controversial to many anthropologists.
"The study also suggests that Indian populations, although currently huge in number, were founded by relatively small bands of individuals - a finding that has clinical implications.
"There will be a lot of recessive diseases in India that will be different in each population and that can be searched for and mapped genetically," Reich said.
"That will be important for health in India."

The Man Of The Mass-Y.S.Rajasekhara Reddy
"Don't count the years you want to live. Ask yourself how much you have done for society at large with whatever opportunities the Almighty has provided you", are the words of Dr.Y.S. Rajasekhara Reddy. The dynamic political leader who proved the worth of his words with his undying spirit of service especially for the downtrodden, met a sad death in a helicopter crash on top of Rudrakonda Hill, 40 nautical miles from Kurnool.

If life is so purposeless, do you feel that it's worth living?
KUBRICK: Yes, for those of us manage somehow to cope with our mortality. The very meaninglessness of life forces man to create his own meaning. Children, of course, begin life with an untarnished sense of wonder, a capacity to experience total joy at something as simple as the greenness of a leaf; but as they grow older, the awareness of death and decay begins to impinge on their consciousness and subtly erode their joie de vivre, their idealism – and their assumption of immortality. As a child matures, he sees death and pain everywhere about him, and begins to lose faith in the ultimate goodness of man. But if he’s reasonably strong – and lucky – he can emerge from this twilight of the soul into a rebirth of life’s élan. Both because of and in spite of his awareness of the meaninglessness of life, he can forge a fresh sense of purpose and affirmation. He may not recapture the same pure sense of wonder he was born with, but he can shape something far more enduring and sustaining. The most terrifying fact about the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death – however mutable man may be able to make then – our existence as a species can have genuine meaning and fulfillment. However vast the darkness, we must supply our own light.

I claim no supernatural authority ....
All religions have for their object the teaching either of devotion, knowledge, or yoga, in a concrete form. Now, the philosophy of Vedanta is the abstract science which embraces all these methods, this it is that I teach, leaving each one to apply it to their own concrete forms. I refer each individual to their own experiences, and where reference is made to books, the latter are procurable, and may be studied by anyone. Above all, I teach no authority proceeding from hidden beings speaking through visible agents, any more than I claim learning from hidden books or manuscripts. I am not an exponent of any occult society, nor do I believe that good can come of such bodies. Truth stands on its own authority, and truth can bear the light of day.
I had a deep interest in religion and philosophy from my childhood, and our books teach renunciation as the highest ideal to which we can aspire. It only needed the meeting with a great Teacher--Ramakrishna Paramahamsa--to kindle in me the final determination to follow the path he himself had trod, as in him I found my highest ideal realized.
Concentrating the powers of the mind is the only way to knowledge. In external science, concentrating the mind is--putting it on something external; and in the internal science, it is--drawing towards one's Self. This concentration of mind we call Yoga.
All morality can be divided into the positive and the negative elements. It says either "Do this" or "Do not do this." When it says, "Do not," it is evident that it is a check to a certain desires which would make us slaves. When it says, "Do," its scope is to show the way to freedom and to the breaking down of a certain degradation which has already seized the human heart.
Those who depend upon the world for enjoyment are the "bound" (tāmasika). Then there are the "egotistical" (rājasika), who always talk about "I," "I," "I." They do great work sometimes and may become spiritual. But the highest are the "introspective" (sāttvika), who live only in the Ātman.
When you give something to a man and expect nothing--do not even expect the man to be grateful--his ingratitude will not affect you, because you never expected anything, never thought you had any right to anything in the way of return. You gave him what he deserved. His own karma got it for him, your karma made you the carrier thereof. Why should you be proud of having given away something? You are the porter that carried the money or other kind of gift, and the world deserved it by its own karma. Where is then the reason for pride in you? There is nothing very great in what you give to the world.

Truth and Sannyasa
Knowledge acquired by the first means is called science; and knowledge acquired by the second is called the Vedas.
Sannyāsa is recognized in the Vedas without making any distinction between men and women. Do you remember how Yājñavalkya was questioned at the court of King Janaka? His principal examiner was Vācaknavī, the maiden orator--Brahmāvadinī, as the word of the day was. "Like two shining arrows in the hand of the skilled archer," she says, "are my questions." Her gender is not even commented upon. Again, could anything be more complete than the equality of boys and girls in our old forest universities? Read our Sanskrit dramas--read the story of Śakuntalā, and see if Tennyson's "Princess" has anything to teach us!

The eternal fragrance of Mahakavi Sri Sri
How does one describe a poet, writer, lyricist, progressive thinker and a great personality like Sri Sri (Srirangam Srinivasa Rao)? It is best to describe him in his own words perhaps. He once said,“1930 daaka Telugu sahithyam nannu nadipinchindi. Aa tharvaatha nunchi daanni nene nadipisthunaanu (Till the 1930s, Telugu literature guided me, after that, I am guiding her). Even after his death in 1983, Sri Sri continued to guide Telugu literature. He would continue to do so, like Mahakavi Gurazada, as long as Telugu language and literature exist.

The day was memorable
hyderabad
April 26: For Mrs D. Lakshmamma, a middle-aged labourer, April 23 was a day of triumph. She was able to cast her vote freely at last, enjoying a privilege which thousands of Dalits have been denied since Independence.
The day was memorable in another sense too. Mrs Lakshmamma, a resident of Bandameeda Harijanawada, a Dalit colony, walked across the main streets of Kalicherla village to reach the polling station. This too was a rare privilege.
The 2009 general elections will be remembered for many things. But for this group of Dalit families, it was a day when they tasted real freedom for the first time, braving the threat of feudal lords who had dominated them all their lives.
“After reaching the polling station I was doubtful whether they will allow me to vote because I don’t have a voter ID card,” said Mrs. Lakshmamma. However, the polling staff allowed her to vote since she had brought her ration card as proof of identity. It may be surprising to many, but in the politically vibrant Chittoor district, there are about 50 villages where Dalits and Muslims do not dare to cast their vote. Elections to local bodies will always be unanimous in these villages that fall in Chandragiri and Tamballapalli assembly constituencies. When elections take place for the Assembly or Parliament the voters’ lists will have the names of Dalits but they will never see a polling booth.
“Ironically, the polling percentage used to be 90 per cent in booths under which the Dalit colonies fell,” said the Chittoor district collector, Mr Ravichandra.
This time, the collector and the superintendent of police, Mr K. Lakshmi Reddy, took the initiative to instill courage among Dalits after some organisations complained to the chief electoral officer, Dr I.V. Subba Rao, about the stranglehold of feudal lords. But the arrogant feudal lords brazenly said that they would spend Rs 1 crore to ‘manage’ the authorities.
To restrain them, the collector ordered the police to slap cases under SC/ST Atrocities (Prevention) Act against those who tried to stop Dalits from voting.
The Dalits are happy at getting the right to vote but are also afraid of retaliation. The district collector has assured them that he would keep a continuous vigil to prevent this.
