The genetic divergence of R1a (M420) is estimated to have occurred 25,000 [2] years ago, which is the time of the last glacial maximum.A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling case for the Middle East, possibly near present-day Iran, as the geographic origin of hg R1a".

R1A1; R1A1 Paratrooper Carbine (Republic of South Africa – Shortened Battle Rifle – 7.62×51mm NATO) R2A1 (Republic of South Africa, UK – Battle Rifle – 7.62×51mm NATO: Licensed Production FN FAL 50.64 Variant) R3A1 (Republic of South Africa, UK – Semi-Automatic Rifle – 7.62×51mm NATO: FN FAL Variant)
Haplogroup R1a is one of the major classifications (called clades) of Y-chromosome types found in human male lines.It is widespread all across Eurasia.Many sample studies therefore carry information on the incidence of R1a and/or its subclassifications, in particular the dominant branching line represented by the haplogroups R1a1 and R1a1a.
The armed forces were re-equipped by 1994 and during this period the L1A1 rifles were gradually phased out. Most were either destroyed or sold, with some going to Sierra Leone. Several thousand were sent to the US and sold as parts kits, and others were refurbished by LuxDefTec in Luxembourg and are still on sale to the European market. [43]
Four of them carried R1a-Z645, while the other carried R1a1-Z283. [78] Mathieson et al. (2018): three Corded Ware males from the Czech Republic. The three were found to be carrying the paternal haplogroups R1a1a, R1a1 and I2a2a2 respectively. [84] [83] Malmström et al. (2019): two Corded Ware males; both were found to be carriers of R1a. [77]
The Remington 1911 R1 is a semi-automatic pistol modeled after the classic Colt 1911 which has served the US armed forces for over 100 years. Like the Colt 1911, the Remington 1911 is single action only, and has a grip safety and a manually operated thumb safety; it also has a Colt Series 80 style firing pin safety.
One subclade of haplogroup R1b (especially R1b1a2), is the most common haplogroup in Western Europe and Bashkortostan , while a subclade of haplogroup R1a (especially haplogroup R1a1) is the most common haplogroup in large parts of South Asia, Eastern Europe, Central Asia, Western China, and South Siberia.

The Ust'-Ishim man fossil of Siberia, dated ca. 45,000 years old, belongs to haplogroup R* (formerly classified as U*). [9] [10]Haplogroup R has also been observed among Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Northern Egypt, which date from the Pre-Ptolemaic/late New Kingdom, Ptolemaic, and Roman periods.
