perhaps this could be a reason:
"An independent genetic study by Partha Mazumder at the Indian Statistical Institute in Calcutta with colleagues at Stanford University and elsewhere has found that the majority of genetic signatures among men in India are older than 10,000 years"

New Genetic Studies Caste Doubt On Aryan Invasion Theory
NEW DELHI, INDIA, January 12, 2006: Two new genetic studies have disputed long-held beliefs that pastoral central Asian people brought agriculture to India and contributed heavily to the genetic make-up of modern Indian populations. The central Asian people who migrated to India included the Aryans who began arriving around 3,500 years ago. The studies by scientists in Calcutta with colleagues in other countries might force historians to revise current ideas about the impacts of migrations from central Asia beginning about 8,000 years ago on India.
A study by scientists at the Central Forensic Science Laboratory in Calcutta has revealed that most present-day Indians are the descendants of early humans who began to arrive in India about 60,000 years ago. It suggests that modern Indians do not owe much genetic makeup to central Asians who arrived much later. The findings do lend support to the migration of people from central Asia into India. "Although we did find genetic signatures from central Asian populations in Indian communities, there are not enough (signatures) to prove large-scale mixture with local populations," research team leader Vijendra Kashyap told The Telegraph.
An independent genetic study by Partha Mazumder at the Indian Statistical Institute in Calcutta with colleagues at Stanford University and elsewhere has found that the majority of genetic signatures among men in India are older than 10,000 years. The study of 1,100 men from 36 ethnic groups in India, 8 in Pakistan and 18 from the southeast Asian region has indicated that many of the genetic signatures have arisen in India and predate the arrival of the Indo-Europeans and their expansion in India. "The genetic contribution from central Asia has not been as large as generally believed," Mazumder said. His study has also indicated that the genetic input of people who might have brought agriculture into India from West Asia has been limited.
