== Race and genetics issues == 

 I realize that 'aryan' and 'indo-european' are more liguistic terms and not related to race. However, the lay person seems to make that connection. Perhaps a small section on the current state of genetics research involving the Indian, European, Central Asian people - their similarities and dissimilarities - can add value to this article. It could tell the reader if any research agrees/disagrees with OIT theory or is neutral/irrelevant. 

 I am looking at it in terms of a casual reader arriving at this article through Internet search or external link. He would probably not read the AIT/AMT or several other related articles. In such a scenario adding a section on race/genetics related issues could give the reader a more complete picture.
