The passages you quoted are still in complete agreement with my quotes. It doesn't show any fallacies in my argument. Furthermore, I have to take issue on the theory that the Nayars are of Newari origin. "In each of the three central kingdoms the Nayar caste was divided into a number of ranked subdivisions characterized by different political functions. Chief of these were (a) the royal lineage, (b) the lineages of chiefs of districts, (c) the lineages of Nayar village headmen and (d) several sub-castes of commoner Nayars. Each of these last either served one of the categories (a) to (c) or else served patrilineal landlord families of Nambudiri Brahmans. I shall deal first with the commoner Nayars of category (d). There were present in each village some four to seven exogamous matrilineages of a single sub-caste of commoner Nayars. These owed allegiance to the family of the head of the village,which might be a patrilineal Nambudiri family, a Nayar village headman's matrilineage, a branch of the lineage of the chief of the district, or a branch of the royal lineage. The commoners held land on a hereditary feudal-type tenure from the headman's lineage and, in turn, had authority over the village's lower castes of cultivators, artisans, and agricultural serfs. Each retainer lineage tended to comprise some four to eight property-owning units which I call property-groups." http://orion.oac.uci.edu/~dbell/Gough.pdf There is a loophole in the theory you posted, and I can drive a truck through it. What's astounding is that of all places close to Nepal(like Bihar or UP), Newars decided to migrate to Kerala??? This is another tin-foil hat theory, if you ask me. There is not an iota of possibility that one can proclaim without a shadow of a doubt that one is "pure", whatever that means. Just think about this example. Suppose my great-grandmother cohabited with a bahun-looking Newar, chances are that the progeny is going to be bahun-looking too, and my great-grandfather wouldn't even have a clue. This type of mixing up must have occured in the past. With all that hormones raging, teens(and most people got married in their teens and hell preteens) will try to experiment. This leads to the result I described. The gotra system of course cannot be used to trace one's ancestry. What are you going to conclude from it, that one of your ancestors was Kashyap?? Australoids are of course not Africans. Australoids have distinct features, like straight hair, that differentiate them from Africans. The Siddhis of India on the other hand are of Ethiopian origin, brought to India by Arabs as slaves. India does not have pure Australoids, but the "taint" can be seen in the phenotypes of many South Indians and North-East Indians. North-Western Indians have been spared of the australoids. They look relatively "caucasoid". As for purity in India, it is just a myth. Read this: "To explore the impact of West Eurasians on contemporary Indian caste populations, we compared mtDNA (400 bp of hypervariable region 1 and 14 restriction site polymorphisms) and Y-chromosome (20 biallelic polymorphisms and 5 short tandem repeats) variation in ~265 males from eight castes of different rank to ~750 Africans, Asians, Europeans, and other Indians. For maternally inherited mtDNA, each caste is most similar to Asians. However, 20%-30% of Indian mtDNA haplotypes belong to West Eurasian haplogroups, and the frequency of these haplotypes is proportional to caste rank, the highest frequency of West Eurasian haplotypes being found in the upper castes." http://www.genome.org/cgi/content/abstract/11/6/994?view=abstract
