Sitara, don't listen to Magdalena. Let me tell you something. I am no biologist, or for that matter an anthropologist. I like reading about people from all around the globe. Let me tell you, she knows jack schitt about genetic studies of Nepalis. Sure, it's true that you won't find studies of bahun/chhetri genes in scientific journals, but you *do* find studies of people like Tharus, Sherpas, etc. Sitara, I own a book by Cavalli-Svorza titled "The history and geography of human genes". It's about 400+ pages of information, and focuses mainly on human migration. He does not believe in the idea of "race", but he does believe that people can intermingle. Separating people by race is flawed, according to him, because there is no clearcut boundary to differentiate various races. Now what he does is he clusters people in terms of genes and the like. Now two Nepali groups are mentioned in the book. The first group he talks about is "Gurkhas"(I am assuming gurungs, rais, magars, etc). This group is close to South East Asians. The other group he mentions is Sherpas. Sherpas are closer to Northeast Asians like Japanese, Chinese, etc. Now even Tharus seem to be predominantly asian(not South Asian) if you go by their genes. Boatloads and boatloads of scientific studies have been done on tharus. Now what's obvious is that Magdalena is retarded. I don't want a retard performing brain surgeries on me, that's for sure.
