J2a-m410 represents the Aryan tribes (In Persia, the Persian's and Medes) dropping from North West Iran deep into the Iranian plateau. In India, these Aryans created a caste system to seperate themselves from the black-skinned Dravidian. The fact that m410 is only found in Upper-Caste Hindu's is consistent with this.
Distribution of M410
It is in all certainty that the areas of high m410 concentration mark the location of the legendary 'Aryan Homeland' as Zoroaster described it. What really gives it away is that Zoroaster often mentions the Araxes river, which borders Iran and Azerbiajan, as part of the homeland.
There is some evidence to suggest, however, that the expansion of the major Haplogroup J around the same region ,about 5000 years before Zoroaster, marks the inital dispersion of the Aryan peoples (Maybe Zoroaster was not describing his birthplace as the Aryan homeland, but rather describing a location that was born from myths originating thousands of years before him, which, only coincidentally, happened to be the land of his birth as well.). This scenario is only plausible after reading Zoroaster's description of a flood on the plateau:
".......In the second phase of the creation of the world, Ahura Mazda created the waters, and the waters flowed towards Farakhekrat Sea which covers one third of the world from the southern outskirts of Alborz"
Obviously, Zoroaster was describing the flood that caused the evacuation of J bearing Iranians long before him, an event he could not have physically witnessed himself. The melting of the ice from the surrounding mountains of the Alborz and Zagros at the end of the last ice age, created a large lake where the central desert exists today (In fact, this lake had still existed just 2000 years ago). It forced many of inhabitants of the plateau to migrate from their homeland. Critics of this analysis would say that Europeans don't carry HG J, so J could not have been IE. This notion overlooks the fact that autosomal comparisons strongly suggest that many specific mutations have been passed on from Iranian peoples into Europe, India, and the Middle East.
