Polish, is a subclade of the larger parent group R-M458, and was first identified as an STR cluster by . In 2010 it was verified to be a haplogroup identified by its own mutation (SNP). It apparently accounts for about 8% of Polish men, making it the most common subclade in Poland. Outside of Poland it is less common. In addition to Poland, it is mainly found in the Czech Republic and Slovakia, and is considered "clearly West Slavic". The founding ancestor of R-L260 is estimated to have lived between 2000 and 3000 years ago, i.e. during the Iron Age, with significant population expansion less than 1,500 years ago. R-M334 R-M334 ([R1a1a1g1], a subclade of [R1a1a1g] (M458) c.q. R1a1a1b1a1 (M458)) was found by Underhill et al. (2009) only in one Estonian man and may define a very recently founded and small clade. R1a1a1b1a2 (S466/Z280, S204/Z91) R1a1a1b1a2b3* (Gwozdz's Cluster K) R1a1a1b1a2b3* (M417+, Z645+, Z283+, Z282+, Z280+, CTS1211+, CTS3402, Y33+, CTS3318+, Y2613+) (Gwozdz's Cluster K) is a STR based group that is R-M17(xM458). This cluster is common in Poland but not exclusive to Poland. R1a1a1b1a2b3a (R-L365) R1a1a1b1a2b3a (R-L365) was early called Cluster G. R1a1a1b2 (R-Z93) (Asia) This large subclade appears to encompass most of the R1a1a found in Asia, being related to Indo-European migrations (including Scythians, Indo-Aryan migrations and so on). R-Z93* or R1a1a1b2* (R1a1a2* in Underhill (2014)) is most common (>30%) in the South Siberian Altai region of Russia, cropping up in Kyrgyzstan (6%) and in all Iranian populations (1-8%). R-Z2125 occurs at highest frequencies in Kyrgyzstan and in Afghan Pashtuns (>40%). At a frequency of >10%, it is also observed in other Afghan ethnic groups and in some populations in the Caucasus and Iran. R-M434 is a subclade of Z2125. It was detected in 14 people (out of 3667 people tested), all in a restricted geographical range from Pakistan to Oman. This likely reflects a recent mutation event in Pakistan. R-M560 is very rare and was only observed in four samples: two Burushaski speakers (north Pakistan), one Hazara (Afghanistan), and one Iranian Azerbaijani. R-M780 occurs at high frequency in South Asia: India, Pakistan, Afghanistan, and the Himalayas. The group also occurs at >3% in some Iranian populations and is present at >30% in Roma from Croatia and Hungary. Geographic distribution of R1a1a Pre-Historical In Mesolithic Europe, R1a is characteristic of Eastern Hunter-Gatherers (EHGs). A male EHG of the Veretye culture
