Haplogroup R (mt DNA) - Origin

Origin

As of June 2009, the most recent study dates the origin of haplogroup R to 66.6kya with a 95% confidence interval of 52.6-81kya.

South Asia lies on the way of earliest dispersals from Africa and is therefore a valuable well of knowledge on early human migration. The analysis of the indigenous haplogroup R lineages in India points to a common first spread of the root haplotypes of M, N, and R along the southern route some 60–70 kya.

Haplogroup R has wide diversity and antiquity among varied ethnic status and different language families in South Asia. In Indian western region among the castes and southern region among the tribes show higher haplogroup diversity than the other regions, possibly suggesting their autochthonous status.

Famous quotes containing the word origin:

    The real, then, is that which, sooner or later, information and reasoning would finally result in, and which is therefore independent of the vagaries of me and you. Thus, the very origin of the conception of reality shows that this conception essentially involves the notion of a COMMUNITY, without definite limits, and capable of a definite increase of knowledge.
    Charles Sanders Peirce (1839–1914)

    There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx’s Capital.
    —W.E.B. (William Edward Burghardt)

    Someone had literally run to earth
    In an old cellar hole in a byroad
    The origin of all the family there.
    Thence they were sprung, so numerous a tribe
    That now not all the houses left in town
    Made shift to shelter them without the help
    Of here and there a tent in grove and orchard.
    Robert Frost (1874–1963)
