The plot shows all CC4 ethnicities clustered close together in the middle, and far away from Africans and East Asians and moderately distanced from Europeans. To keep things within laymen’s comprehension let us say the two axes represent combined DNA information that is significant in studies of this type. They plot on each of two axes two such composites that they call a “multidimensional scaling plot” of 18 world ethnicities including CC4. The researchers had to combine many findings together to deduce recognisable group features. Polymorphism is when several traits or tendencies co-exist (O, A, B and AB blood groups are universal in all populations). That’s all now call me a knit picking bastard and get on with the paper, it’s worth exploration even if you are not in the field.Īn interesting finding is that CC4 people can be marked off from other populations. And third, among its historical references I see lesser works but no mention of Professors Leslie Gunewardana and Karthigesu Indrapal, clearly the best and most relevant historians in this field. Then who the devil was Ellalan (எல்லாளன்) didn’t he rule Anuradhapura from 636 to 604 BC? Secondly the paper always uses the term “Indian Tamils”, not Upcountry Tamils – this is gibberish, all of us are from the Indian Mainland. The Introduction says the Tamils turned up in the island in the “fifth century AD”. However, before proceeding allow me to make three mild criticisms. Yes, it was mostly Greek to a moron like me, but if you are persistent, look up hard words and reflect on a watered-down understanding (no doubt to the chagrin of the authors) you can learn quite a bit. Now turn from the video which is for popular consumption to the scientific paper.
Surely this must arouse your intellectual appetite.
