It is well known by Indian scholars that what yanniru said about the age of the Indian culture is correct. However, the present thought of Indian scholars like Pak in the USA is that the Aryan invasion theory is incorrect. If anything, what are called Aryans originated in northern India and migrated to the west, according to Pak. What may have happened is that the tribes in northern India made contact with the southern tribes some 8000 plus years ago resulting in the flourishing of civilization in the Indus and Saravasti River basins. It seems that the British promotes the Aryan invasion theory to support their colonization of India

From the preface: "River Sarasvati has exercised great fascination and unfailing interest in the minds of geologists and archaeologists of India. The 'lost' character of this once mighty river, extolled in superlative terms in Rigveda--the oldest texts available to mankind--is possibly one of the reasons why this river has generated such unflagging interest in the minds of scholars and scientists. There have been many conjectures as to its former course and the literature on the subject is fairly substantial.
"The interest attached to Sarasvati is also because of the great civilization which flourished on its banks more than 8000 years ago. This ancient civilization is believed to have come to a sudden end as a result of neotectonics as well as climatic change. Due to these causes, river Sarasvati which once flowed in true majesty dwindled into an ephemeral stream and finally got lost in the sands of the Thar desert. The river thus has a fascinating history which requires to be carefully analysed and a convincing evolutionary chronology established.
"The Geological Society of India thought that the time was ripe to hold a group discussion, bringing together persons of different disciplines engaged in the study of one or the other aspects of the birth, growth and demise of Sarasvati. Thanks to the keen interest evinced by Professors S.S. Merh of the M.S. University of Baroda, Vadodara, and K.S. Valdiya of the Jawaharlal Nehru Centre, Bangalore, who are themselves keen students of neotectonism, it was possible to bring together a wide cross section of talent and focus attention on different aspects of the problem. The papers presented at the discussion meeting form the bulk of the present volume. Apart from these newer additions to our knowledge, it was felt desirable to include some of the classical writings of earlier workers also, so that the volume could form a source book of information to all future workers."

Scientists Find Link Between Indian Caste Rank And Genetic Similarity To Europeans (May 15, 2001) — In India, members of higher ranking castes are genetically more similar to Europeans, while lower castes are more similar to Asians, according to a study published in this month’s issue of Genome Research.
Mike would profit from arguing from evidence rather than semantics. Claiming that yanniru is guilty of invasion is evidence of irrational thinking
