Hello AllieKat,
In general Indian's are Indo-European. It is very possible that people from the fertile cresent moved into India and Central Asia as the Ice melted. Some folk went from the fertile cresent further East and others moved North-West into central Europe. If we take one example of lanugage such as the word Yoga we see this word in English as Yoke, meaning to unify.
So called European Haplogroups are found in India but just in smaller percentages. Similarly so-called Asian Haplogroups are also found in European populations. It's all a matter of degree.
Have a look at the Genographic project on-line, here you will see what I mean. Just to clear up my side I am of both British and Australian Aboriginal descent, I am a child of colonisation. The Aboriginal people moved from southern India to Australia, along the coasts of now marine landscapes, when sealevels changed in relation to the northern and southern Ice melt.
Black, Yellow, White etc.... has more to do with environmental adaption in the last 70,000 years. The gene for blue eyes and fair hair is only estimated to be approx. 6,000 to 9,000 years old. This is when folk in Europe still had brown/copper coloured skin. Vitamin D adaption in relation to the lack of sun in northern Europe has a lot to do with fair skin. the more north you go the more important it was to be fair. It is also very possible that selective breeding took place as fair skin people experienced better health in such conditions. Similarly within the caste system of India, the more you do not have to work in the sun, the lighter your skin will be.
So socialisation within populations has been the second causation for so-called "difference", due again to selective breeding.
All the very best!
