Plus some mt DNA support . Eurasian mt DNAIn addition , the frequency of mtDNA haplogroups with a more recent coalescence estimate i . e . , H , I , J , K , T was fivefold higher in upper castes 6 . 8 % than in lower castes 1 . 4 %. These haplotypes are derivatives of haplogroups found throughout Europe Richards et al . 1998 , the Middle East Di Rienzo and Wilson 1991 , and to a lesser extent Central Asia Comas et al . 1998 . Collectively , the mtDNA haplotype evidence indicate that contemporary Indian mtDNA evolved largely from protoAsian ancestors with Western Eurasian admixture accounting for 20 % 30 % of mtDNA haplotypes . <| sep |> I would assume some kind of heart failure ? <| sep |> Dammit , I ' ve been waiting to try cat h them practice landing at the hospital .
