Talk:Haplogroup R (mtDNA)

Soares et al 2009
A new study by Soares et al Correcting for Purifying Selection: An Improved Human Mitochondrial Molecular Clock has new dates for the origin of haplogroup R. The study claims to be the most accurate as it has considered the whole genome, both coding and non-coding regions. The article dates haplogroup N to 66,600 years ago with a 95% confidence interval of 52,600-81,000. The study places the Out of Africa migration at 55-70kya. As these dates overalap with the origins of haplogroup R, both an African and Asian origin are possible. The supplemental materials are available for free. M is on page 83. The image of the phylogenetic tree is available here In the government (talk) 18:50, 1 July 2009 (UTC)


 * I haven't seen any research suggesting an African orgin for haplogroup R (mtdna). Since it has been established that R's parent haplogroup N is of SW Asian orgin, it doesn't seem likely for R to be of African origin. I don't know of any populations that have markers for mtdna HAplogroup R in Africa. I know that R0 is in NE Africa as part of a back migration. -192.172.8.13 (talk) 14:05, 14 July 2009 (UTC)


 * Yes, indeed. It's absolutely impossible to think in an african origin for haplogroup R (ADNmt). --Maulucioni (talk) 04:35, 16 July 2009 (UTC)

2014 paper on 45,000 Siberian genome
There a 2014 paper from Nature on Google Scholar, Genome sequence of a 45,000-year-old modern human from western Siberia about Ust'-Ishim man. He had his complete genome sequenced. "The Ust’-Ishim mtDNA sequence falls at the root of a large group of related mtDNAs (the “R haplogroup”)". The paper got 323 cites. Here's the free version: [nih.gov]

Pre-Ptolemaic
"Haplogroup R has also been observed among ancient Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from the Pre-Ptolemaic/late New Kingdom, Ptolemaic, and Roman periods.[11]"

This term is problematic, because by conflating the late New Kingdom and later invasions into 'Pre-Ptolemaic', it implies a foreign influence in Egypt only started with the Greeks. Problem: the Greeks defeated the Persians, who'd defeated the Assyrians, who'd defeated the Libyans, to get to the throne in Egypt. In fact all reference to the conclusion of the Schuenemann study published in Nature are problematic. The Nature study. (NATURE) Ancient Egyptian mummy genomes suggest an increase of Sub-Saharan African ancestry in post-Roman periods. A response from professor Alain Anselin, supported by prof. S.O.Y. Keita. Ancient Egyptian Genomes from northern Egypt: Further Discussion. Other problems with the study are that they only consider Sub-Saharan/Yoruba dna to be 'African' and not northern and southern Nile Valley dna (Dinka, Nuer, Nuba). They consider the mtdna haplogroup M1 to be non-African, although it is huge in East Africa, and is directly derived from L3. Their timely is not representative of history. Their dna research is limited to haplogroups, and the whole genome of 3 individuals. And lastly they did not compare AE dna to their direct Nile Vally or Saharan neighbors. And, they categorically reject results from PCR STR testing. So the Schuenemann study is very problematic, and the use of the term pre-Ptolemaic is emblematic of that. 83.84.100.133 (talk) 15:55, 8 February 2020 (UTC)

Orphaned references in Haplogroup R (mtDNA)
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Haplogroup R (mtDNA)'s orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Kutanan2016": From Haplogroup M (mtDNA): Kutanan,W., Kampuansai,J., Srikummool,M., Kangwanpong,D., Ghirotto,S., Brunelli,A. and Stoneking,M., "Complete mitochondrial genomes of Thai and Lao populations indicate an ancient origin of Austroasiatic groups and demic diffusion in the spread of Tai-Kadai languages." ''Hum. Genet.'' (2016). From Haplogroup C (mtDNA):  From Haplogroup N (mtDNA):  From Haplogroup B (mtDNA): Wibhu Kutanan, Jatupol Kampuansai, Metawee Srikummool, Daoroong Kangwanpong, Silvia Ghirotto, Andrea Brunelli, and Mark Stoneking, "Complete mitochondrial genomes of Thai and Lao populations indicate an ancient origin of Austroasiatic groups and demic diffusion in the spread of Tai–Kadai languages." Hum Genet 2016 DOI 10.1007/s00439-016-1742-y. 

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 07:42, 22 May 2020 (UTC)
