Even though the skins of Indians is dark, they are both linguistically and genetically closer to Europeans than they are to Asians or Africans. After all, English and most other European languages are "Indo-European".
Look at the facial features of most Indians, especially those from northern India. Take away the dark complexion, and they could easily pass as a European. If you give a black or an east Asian a white complexion, he won't look European. He'll just look like an albino.
I have often wondered if "genetic closeness" was one of the reasons why the British Raj in India worked so well.
If you think about it, it probably took the ancestors of the Indian subcontinent and the Western Europeans about the same length of "geological time" to get from the Caucasus region of Eurasia to India and England, respectively.
I've always noted that when I was in college, the Indian students always seemed to "think more like" I did (me-- Anglo-Saxon on both sides)than even many of the Eastern European types. And both Indians and Brits are "eccentric" in many of the same ways. Cultural?? or genetic?? Or both??
