Can someone succinctly describe what the "caste groups" are as distinct from
the "tribal groups"? I have heard about high caste and low caste, but are
the tribal people outside of the caste system?

>> Actually the data is now almost overwhelming that
R1a emerged in northern Pakistan or India and spread
north, south, east and west from that point.
Counter to the claims of Kivisild et al. (2003),
Cordaux et al. (2004) "conclude that paternal lineages
of Indian caste groups are primarily descended from
Indo-European speakers who migrated from central Asia
approximately 3,500 years ago."
Cordaux et al. criticize Kivisild's assertion which
was based on a single tribal group: "Thus, the
unusually high frequency of R-M17 in the Chenchu tribe
(27%) is not representative of other tribal groups and
hence cannot be taken as evidence for an Indian origin
of R-M17, as claimed previously ."
Instead of an Indian origin, a Central Asian origin
for R-M17 in Indians is affirmed: "Given the high
frequency of R-M17 in central Asia (typically 20%-40%
), its rarity in west Asia [9 and 13] and its
absence in east Asia , Indian R-M17 Y chromosomes
most probably have a central Asian origin [8 and 9]."
