The human male specific Y-chromosome passes from father to son essentially unchanged, but occasionally a random change, known as a mutation, occurs. These mutations, also called markers, serve as beacons and can be mapped. When geneticists identify a mutation in a DNA test, they try to determine when it first occurred and in which part of the world. Thus, the Y-chromosome haplogroup, which is a population group descended from a common ancestor, can be used to trace the paternal lines of men. The poster describes a research project that aims to identify the ancient geographical origins of key ethnic communities of the Indian subcontinent, based on their Y-DNA haplogroups.

METHODOLOGY: Eight different haplogroups were identified from asample of haplotypes of key ethnic communitiesof the Indian subcontinent. A haplogroupprediction software program was used. Thedefinitions of haplogroups were used todetermine their deep ancestries.

Most surprisingly is that this team made a Phylogenetic tree with T-M184 downstream P-M45

And ASTONISHINGLY they found 9% of I haplogroup among the Total sampled populations.

Oh man I thought it was a serious study. Looks like an undergraduate research project. Ran a bunch of haplotypes from the literature through a haplogroup predictor that's trained on Europeans I guess.
