Recently I watched a documentary called
The Story of India It started in Tamil Nadu and went all the way to Kolkata, then Mathura, Hasthinapura, Peshawar and even to Turkmenistan to trace the origin of the Aryans. It talked about the nature worship in the Vedas and even discussed Somarasa. It seemed reasonably scholarly and well researched.
Now knowing that this may be considered a politically hot topic, let's have a show of hands: how many believe that there may have been an Aryan race which invaded India from the north-west and slowly migrated southwards and eastwards? And that there was one or more indigenous races that they "interacted" with.
Aryan theory got some traction during the time of British Raj because of the linguistic similarity between Sanskrit (& its derivatives) and Indo-European languages like German, which has NO similarity with any of the Dravidian languages of the South India.
Furor, the Third Reich propagated the Supremacy of the Aryan race in Germany, and many Indian scholars also subscribed to the theory that nomads of the Central Asia migrated towards West going to Germany and South towards India. Present day Kazakstan could be the place of migration from to Germany or India.
The distinct melanin pigment difference in Indian population gave some credence to the Aryan Invasion Theory: Northern Indians have very low melanin pigment (similar to Aryans of Germany) and Southern Indians have high melanin pigment in their skins (the Dravidians). Of course, there is a continuum of color (melanin concentration) from the North to the South.
How to understand this Aryan and Dravidian Race in India? Population geneticists, mitochondrial geneticists and anthropologists have this hypothesis - All evolutions of human race happened in Africa near Kenya - Homo erectus and Neanderthals from Africa migrated towards Europe and Asia about 200,000 years ago..Homo erectus evolved into Homo sapiens and settled in Northern Asia, and Neanderthals occupied Europe. Around 150,000 years ago, there was another wave of migration from the Homo sapiens of Africa who moved into Persia, South Asia to Australia - these people are the original peoples of India (the dark skinned - the high melanin pigmented Dravidians)...
Then after about 5000 years ago, the people settled in the Central Asia migrated towards South, and some of them came to North India... this could be the Aryans who had plenty of horses and chariots: their Southward movement was successful because they were nomadic tribes who could fight their way through any inclement weather and opposition...Dravidians did not have horses and chariots and they could not stop the Aryans from the Central Asia.
Then what happened? After initial rebellion against the Aryans, the Dravidians started co-habiting in the North India and there were marriages between the light colored Aryans and dark colored Dravidians.
The genes that code for melanin pigments, processing, packaging and maintenance are mutated and the mutant alleles are there in all Indian families after cross-marriages in the past 5000 years at least: This produces different shades of skin color among family members - among Brahmins there are very dark skins and very light skins... even among Dravidians there are very light skinned people.
My view is in all of us there are alleles of Aryans and Dravidians... therefore, we NEED not use the Aryan "Invasion" as a divisive matter in our culture and political process.
President Obama called himself as a Cross Breed.. likewise, all most ALL Indians are Cross Breeds.
Cheers.
