Original sentence: According to one genetic study, the Vedda are similar to the Tamil and Singhalese and, like them, also have a considerable occurence of West Eurasian haplogroups (at about two third), but the Vedda also differ from some other tribal groups in mainland India.The Vedda belong predominantly to the mitochondrial haplogroups N and its subgroups U and R, which are most common in West Eurasian populations.The Vedda had been described in earlier sources as "baseline of the "Caucasoid blood" and some describe a "Veddoid substratum", "a mixture of Caucasoid and Australoid", to be common in ancient Southeast Asia and Sundaland.also, while also noting the distinctiveness of between South Asian (including Vedda) and Andamanese crania, explain that this is not in conflict with genetic evidence showing a partial common ancestry and genetic affinity between South Asians and the native Andamanese (a common ancestral genetic component known as "Ancestral South Indian" or "ASI"), stating that "The distinctiveness of Andamanese and southern Indian crania need not challenge the finding by Reich et al
Edited sentence: According to one genetic study on maternal haplogroups, the Vedda belong predominantly to the mitochondrial haplogroup N and its subgroups U and R (with those comprising about two thirds of their maternal lineages), differing from other South Asian groups (such as the Sri Lankan Tamil and Sinhalese) among whom haplogroup M is predominant.The study also found that "South Asian (Indian) haplogroups were predominant" but that the Sinhalese, Sri Lankan Tamil and Vedda populations also "had a considerable presence of West Eurasian haplogroups.also, while also noting the distinctiveness of between South Asian (including Vedda) and Andamanese crania, explain that this is not in conflict with genetic evidence showing a partial common ancestry and genetic affinity between South Asians and the native Andamanese (who are sonetimes classified as "Australoid"), stating that "The distinctiveness of Andamanese and southern Indian crania need not challenge the finding by Reich et al
