| In ], '''Haplogroup R1a''' (M17) is a ] ], that is spread across ]. | |||
| It is common in ], Northern ] and ]. In Europe the highest frequencies are in ]. Today it is found at over 40% frequencies in many ] countries, with some notable exceptions (60% Poland). Relatively high frequencies are also found in ] and is believed to have been spread across Europe by the ], which accounts for the existence of it in among other places the ]. It is however fairly common across all of Europe. In ] haplogroup R1a is found in both the Hindu ] and ] populations, and it is most diverse in tribal, rather than caste populations, therefore researchers have concluded that it is not necessarily a signature of Central Asian origin . | |||
| R1a is related to ] (M343) which is dominant in ]. Both are offshoots of ] (M173). | |||
| R1a has two subgroups: R1a1, in which the M17 mutation is present, and R1a*, in which it is lacking. | |||
| ==Origins== | |||
| The first carriers of the R1a1 are believed to have been nomadic farmers in the steppes of northern Central Asia about 10,000 years ago. Current theories point to them being the first speakers of the proto-Indo-European languages (the ] culture) and the first ones to domesticate the ]. | |||
