Article Grading: The following comments were left by the quality and importance raters: (edit · history · refresh · how to use this template) There is no source for the statment that Haplogroup J2 is found in 33% of Greek males. According to the paper "Y chromosome variation in Jordan" by Flores et al, 24.5% of Greeks carry Haplogroup J2. The following statement "The less-heterogeneous J2 (J-M172), which occurs as frequently as J1( J-M267) in some Middle Eastern populations, is the more prevalent in Europe." is Misleading. J2 (J-M172) is NOT more prevalent in Europe. The statement seems to state that J2 is more common in Europe than the Middle East. It is however, the more common type of Haplogroup J that is found in Europe. 99.239.249.134 (talk) 16:52, 24 November 2007 (UTC) |

This article contradicts the Wikipedia article on Haplogroup J. Some of the info in this article is misleading, especially with respect to the frequency of Haplogroup J2 among Jewish males. Most published data show Jewish men, sephardic and Ashkenazi, carry Haplogroup J2 (M172) at about twice the rate of J1. The age of the M172 marker is estimated by Spencer wells to be 10K years old in his latest book, not 18,500 +-3500 years as stated in this article. 66.135.96.138 21:21, 6 March 2007 (UTC)
-Haplogroup J2 is not mainly found in Europe according to geneticist spencer wells and Semino et al, they simply state that haplogroup J2 as compared to J1 is found more frequently in Europe. Many Middle Eastern populations have rates of J2 that are numerically and percentage wise much higher than European populations, where it is observed at moderate frequency only in the Mediterranean region. Furthermore, in the northern Levant, J2 is seen as the older substratum of J and is found in semitic populations in Lebanon, Iraq, Palestine, Jordan. —Preceding unsigned comment added by 129.64.72.124 (talk) 18:55, 11 September 2007 (UTC)
[edit] Proposal to create a new WikiProject: Genetic History
I have put up a suggestion at Wikipedia:WikiProject Council/Proposals to create a new WikiProject, WikiProject: Genetic History.
To quote from what I've written there:
-
- Description
- A wikiproject for articles on DNA research into genetic genealogy and genealogical DNA tests; the history and spread of human populations as revealed by eg human Y-chromosome and mitochondrial DNA haplogroups; and similar. Many such articles can be found in Category:Genetic genealogy and its subcategories, notably the subcategories on human haplogroups.
-
- Rationale
- My direct motivation for seeking this Wikiproject was a recent run-in at Y-chromosomal Aaron, where I desperately missed the lack of a relevant WikiProject talk page to go to, to attract the input, advice and views of knowledgeable editors in this area.
- There's a lot of general public interest in the proposed subject area -- eg the Y-chromosomal Aaron page is apparently getting well over 100 hits a day, and over the last 18 months or so there's been a lot of material added, by a fair number of different editors, mostly editing different pages which are particularly relevant to them. IMO, a central wikiproject would be useful, and also a good place to be able to bring WP:OR, WP:V, and WP:general cluelessness issues for wider informed input.
- Wikipedia:WikiProject Molecular and Cellular Biology and Wikipedia:WikiProject Evolutionary biology do already exist, but their focus is much much broader. With regard to those project's charters, I believe the subject would be seen as a rather specialist niche topic area, rather out of the mainstream of those project's normal focus. On the other hand, I believe that there are a number of wikipedia editors (and readers) who are specifically interested in the subject, who would find advantage if there were a specific wikiproject for it.

If people think this would be a good idea, it's a target for WikiProjects to have at least five "interested" signatures to show there's some support, before they get going.
Alternatively, if people think it would be a bad idea, please leave a comment in the comments section.
Either way, please show what you think, at Wikipedia:WikiProject_Council/Proposals#Genetic_History
