BioEssays 29.5 497 *http://en.wikipedia.org/wiki/Dravidian_languages Correspondence M haplogroup samples. The geographical range of Indian M haplogroups is explained by the coalescent theory, i.e. the small Proto-Dravidian population that settled the Indus Valley expanded and spread over the subcontinent from Pakistan in the North to South India.

The Dravidian speakers are probably not autochthonous to India as claimed by Chaubey et al. It is clear that the Dravidians and Africans speak genetically related languages, (5,13 -21) and share anthropological and archaeological features that unite both groups. The presence of M1 in India, and the absence of Indian-specific clades in Africa, indicates that Indian M subclusters probably developed in India, after the migration of proto-Dravidian speakers from the Indus Valley down into South India. This path for Dravidian migration may be marked by the spread of (1) shared toponyms, (2) genetically related languages, (3) skeletal remains, and ( ) red-and-black pottery.

The origin of the beta C mutation was studied by characterizing nucleotide sequence polymorphisms on beta C chromosomes of patients from various African countries. In the majority of cases, the beta C mutation was found in linkage disequilibrium with a single chromosomal structure as defined by clas
