WARNING- THIS IS IN NO WAY MEANT TO BE RACIST, CASTEIST AND DISRESPECTFUL.
1. Jats, Gujjars, Rors- Tallest among all south asian groups with the most Caucasian skull shape. This is due to more west eurasian ancestry that also gives them lactose tolerance. Also mostly rich with a lot of ancestral wealth.
2. Brahmins, Rajputs and other kshatriyas - Again, the same reasoning but they have a bit less West eurasian ancestry and mostly have more South Asian hunter gatherer ancestry.
3. Central indians - This includes Biharis, and other central indian groups like the Gujratis.
4. South indians - typically short and their skull shape is also not caucasoid. Lowest smv because of this.
