Haplogroup K2-M70 in East India and East Africa

Rasta Livewire Science Corner

A study of Indian Y-chromosomes R. Trivedi et.al “High Resolution Phylogeographic Map of Y-Chromosomes Reveal the Genetic Signatures of Pleistocene Origin of Indian Populations” tested for haplogroup K2-M70 in India.

Haplogroup K2-M70 Y-chromosomes were found only in two regions of India: East India, which is considered to be originally territory of the Mundaic peoples (a western subgroup of the Austro-Asiatic language family) later overlain with an Indo-Aryan (primarily Oriya and Bengali) adstratum, and the eastern coast of South India, which is inhabited originally by speakers of South-Central Dravidian (e.g. Telugu) and South Dravidian (e.g. Tamil).

Haplogroup K2-M70 was not found among the study’s samples of populations in West India, North India, or Northeast India.

Haplogroup K2-M70 was found in 4/179 (2.2%) Austro-Asiatic tribal samples, 14/126 (11.1%) Dravidian tribal samples (mainly among Kurru AKA Yerukalas AKA Erukalas AKA Erukulas), 0/92 (0.0%) Tibeto-Burman tribal samples, 3/108 (2.8%) Indo-European tribal samples, 0/72 (0.0%) Dravidian upper caste samples, 3/58 (5.2%) Dravidian middle caste samples, 0/137 (0.0%) Dravidian lower caste samples, 0/132 (0.0%) Indo-European upper caste samples, 0/117 (0.0%) Indo-European middle caste samples, and 12/115 (10.4%) Indo-European lower caste samples.

Every one of the 36 haplogroup K2-M70 samples from East/Southeast India had a distinctive haplotype, which results in a 1.000 (100%) lineage diversity value.

Haplogroup K2-M70 is very widespread across Africa, indicating human and cultural dispersion between the two continents.

As for the distribution of haplogroup K2-M70 in Africa, it seems that it reaches its highest frequency among certain groups of Fula people (sometimes called the Fulbe or the Fulanis), particularly those dwelling in the Sahel belt that stretches across southern Niger, northern Nigeria, northern Cameroon and Eriteria.

Haplogroup K2-M70 also seems to be rather common among Somalis, some Ethiopian and Sudanese ethnic groups, Egyptians, Omani Arabs, and Iraqi Arabs. It also has some presence among various ethnic groups (mostly Bantu-speaking) in Kenya and Tanzania.

Clearly haplogroup K2-M70 in East India and East Africa, suggests a level of kinship that deserves more studies. This is all the more imperative given the testing of another Y-DNA chromosome known as haplogroup E-M96 which is a close relative of haplogroup Indian D-M174.

  1. Just looking at people from the mentioned nations one can see related features…
    J.A.Rogers wrote on this type of issue before dna testing was developed for relatedness
    between ethnic-race groups.

  2. Unless we can identify the results produced by these genetic mutations, we’ll continue to be at a loss to understand or dispute Euro-Science.

    http://en.wikipedia.org/wiki/Adipose_tissue

    According to Wikipedia our LPL or lipoprotein lipase acts to break down our adipose fat transforming it into triglycerides (The Good Cholesterol). The Mutation 207 or M207, (a deletion or partial deletion of the LPL gene) which according to geneticists represents the marker for the R haplogroup, stops this from happening of resulting in a genetic defect that produces atherosclerosis the primary cause of heart disease. Now why would nature decide to delete DNA that performed a perfectly beneficial human biological function?

    The only reason FAT storage is necessary is if you belong to a species of human adapted to a FRIGID CLIMATE; a.k.a. the Neandertal. What might have been beneficial to the Neandertal is deadly to his descendents; adapted to a warming planet. This mutation would have been unnecessary to an African Human because the Last Glacial Maximum or Ice Age merely brought drought to the Northern regions of the African Continent.

    I’ve searched the web for an explanation of the M173 mutation without success; the M173 has a high Y Chromosomal frequency in Cameroon West Africa, Euro-Science would like to attribute this to a back migration from Asia, except they have been unable to find the corresponding Euro-Asian MtDNA. This theory of a back-migration would fit very nicely into their theory of an Asiatic origin for Nilotic civilizations. No explanation is found for the M168 mutation either; the Y Chromosomal Adam. Until we acquire knowledge of the benefits or disadvantages these mutations bestowed, we’ll be left groping in the Dark.

  3. I’m particularly interested in responses to the Neanderthal Theory. I find it so very interesting and although the author is convinced it proves Caucasian superiority, I find it provides most of the proof Modern Africans need to prove that the African Eve was indeed violated by the skin sloughing, biblical serpent, tand he rest of us must attone for that sin.
