Category Mummies

I don't believe that the Cheddar man should be in the category "mummies" if the article states that he was a complete human skeleton. --Your's Truly,

Problems with this article

U5a is most common in Finland and areas near Finland (not France or Spain). High frequencies are found in Finland, Estonia, Russia (european side), Sweden and especially in Norway. Ancestors of the Cheddar man most likely came from Fennoscandian peninsula or area next to it. Mtdna in european populations:

On another topic, the article says "the cannibalism practiced in the area". I think that should be rephrased to make it clear that the cannibalism was practiced in the area at the time of cheddar man.

I changed that sentence. Let me know if it's not clear enough. -BlackTerror 14:12, 15 March 2007 (UTC)
The link above no longer works. Should there be a reference in support of the assertion that cannibalism was practised in the area? 139.163.138.15 (talk) 05:50, 30 October 2008 (UTC)

Is Cheddar man a real "fossil" in the true geological sense of the word? Some would say it is simply a well preserved skeleton.  Preceding unsigned comment added by 109.159.15.46 (talk) 10:47, 26 February 2018 (UTC)

It's a little older than the arbitrary limit of 10,000 years before present. Richard Keatinge (talk) 12:17, 26 February 2018 (UTC)

Middle eastern origins

"...may have originated in West Asia"

"...lends extreme credence to the theory that modern-day Britons are not all descended from Middle-Eastern migratory farmers"

These two phrases contradict each other. Grant | Talk 10:33, 1 May 2007 (UTC)

Not when considering that the beginning of agriculture is considered to be much later, and came from the middle-east in another, much later, wave. It's just saying that they are not the "migratory farmers" of that later wave. Nagelfar (talk) 05:21, 10 January 2008 (UTC)

This is completely off topic to the "Cheddar Man" topic. It is well known that Paleolithic Europe was colonized from West Asia around 40 kya, the dedicated entry for that being European early modern humans. It is also well known that this lineage (dubbed "WHG") contributes substantially, but to less than 50%, to most modern European populations, the other significant contributions being EEF (Neolithic) and ANE (Chalcolithic). Cheddar Man is just a data point in this topic. The problem with writing this kind of article based on journalism is that the journalists are going to give a garbled overview of the wider field related to the topic, but our encyclopedic articles should instead try to remain focused on what is WP:DUE. Please discuss Cheddar Man's genome here, but discuss the WHG lineage at West European Hunter-Gatherer, and the general topic of the genetic ancestry of British populations at Genetic history of the British Isles, and then refer to these pages for details. Also avoid using journalistic "references" as much as possible, it is just as easy and much more useful to just cite the original paper directly. All that we need to note here is that Cheddar Man is compatible with WHG. If there are any details on genetic difference to the WHG reference genome, do point them out, but don't go on a tangent explaining what WHG means, let alone how "modern-day Britons are not all descended" from this or that stock (which is true a priori because of the undue weight carried by the all in this sentence). --dab (𒁳) 15:25, 7 February 2018 (UTC)

WHGs were different than Paleolithic Europeans or even only slightly older El Miron cluster. Oranjelo100 (talk) 16:59, 9 February 2018 (UTC)

Sources

I have looked into the sources cited a bit more based on my comments above. Two observations:

  • the result that Mesolithic European populations (WHG) appear to have had dark skin and blue eyes dates to 2014 and is already well represented on the relevant Wikipedia articles. There are several Mesolithic genome analyses supporting this, from Spain, Luxembourg, Sweden, and possibly elsewhere, which have been published academically since 2014. They are cited at the appropriate place, in the blue eyes and European early modern humans.
  • the 2018 Cheddar Man study appears to align this individual with WHG, which is plausible, but the study has apparently not yet been published(?). The best source we seem to have is this, which seems to imply that this was done for a Channel 4 program. The tendency to publish scientific findings in television programs before they have even been peer-reviewed is absolutely deplorable, and if this is indeed the case here, this needs to be pointed out front and center in the article. --dab (𒁳) 15:53, 7 February 2018 (UTC)

Skin colour

The article claimed that Cheddar Man had black skin even though the sources only say "dark complexion" and "dark skin". According to this article and video on bbc.com, which shows the "official" reconstruction of Cheddar Man, based on the DNA analysis, his skin was brown, not black. I was about to change it, but an IP beat me to it, but just to avoid edit-wars over it I thought I'd post a link to the video here... - Tom | Thomas.W talk 20:34, 7 February 2018 (UTC)

It may have been me that introduced that term as I saw the Guardian article this morning which said "dark to black skin" and quickly edited the article before going to work, but happy for a consensus term to emerge. Rod talk 20:43, 7 February 2018 (UTC)
I changed it to black, based on the independent article, the citation i added to the previous sentence. I am happy to go with the consensus.-- BOD -- 23:37, 7 February 2018 (UTC)
We really need a recent pic for the article...its a classic example where an image explains it better than words -- BOD -- 23:40, 7 February 2018 (UTC)

The Guardian is not a source. This is about journalists asking "could we even say ... black?" until the scientists go "yes, if you must", hence the headline "ZOMG FIRST BRITON WAS BLACK". If you want encyclopedic information on WHG skin color reconstruction, don't go to journalists. The Cheddar people are just reporting they have found an allele in this skeleton that has already been well described elsewhere. For the description of said allele, go to SLC24A5 and SLC45A2. "Derived immune and ancestral pigmentation allelesin a 7,000-year-old Mesolithic European" Nature, January 2014. doi:10.1038/nature12960 and related publications. : Wilde, S. et al. "Direct evidence for positive selection of skin, hair, and eye pigmentation in Europeans during the last 5,000 y." Proc. Natl. Acad. Sci. U. S. A. 111 , 4832-4837 (2014).

Whatever you do with this, make sure the discussion is based on actual publications, ignoring journalism. --dab (𒁳) 06:14, 8 February 2018 (UTC)

Yes, if available, academic and peer-reviewed publications are usually the most reliable sources, in fields such as in history, medicine, and science. However reliable non-academic sources may also be used in articles about scholarly issues, if the source, particularly material from high-quality mainstream publications, has a reputation for fact-checking and accuracy. Deciding which sources are appropriate depends on context and availability.-- BOD -- 11:33, 8 February 2018 (UTC)
More information Unfounded conspiracy claims ...
Close
The Telegraph, The Independent, The Guardian, The BBC, The New Scientist, The Natural History Museum and the University of Central London are simply not tabloids. The rest of what you have written is not worthy of a reply.-- BOD -- 20:01, 10 February 2018 (UTC)

Your conspiracy theory that they aren't tabloid,especially the guarding, the bbc and the dailht telepgraph proves they are based on previous tabloid behavior and articles. Elvis is still alive is considered tabloid. and since you didn't have a argument and admitted you were wrong since you didn't address the other argument then yes, they are tabloids and the rest was true aswell.77.53.219.61 (talk) 00:15, 11 February 2018 (UTC)

The Guardian, BBC, and Daily Telegraph don't fit the standard definition of "tabloid" and you don't even attempt to offer a coherent definition of the term that somehow fits. The rest of your logic string doesn't fare much better. Besides you are frankly wrong about what those publications said. The BBC and Guardian both in headline and copy say researchers said that the man likely had "dark to black skin" which is exactly what researchers did say. The Daily Telegraph I'll grant you somewhat overstated by just saying "black" but it's not like that slight distinction is so monumental as to mean they are a sensationalistic tabloid and not to be trusted. Absolutely none of the articles describe Cheddar Man as being "sub-Saharan African." The rest of the theory is rubbish.  Preceding unsigned comment added by 204.117.223.5 (talk) 18:56, 15 August 2018 (UTC)

Can haplogroup issue be clarified, please?

Article says:

In 1996 ... Cheddar Man was determined to have belonged to Haplogroup U5 ....
Around 10% of Europeans belong to Haplogroup U5 .... it was suggested that the sequence was from contaminating modern DNA.[7]
The full genome was extracted ... in 2018.[8] The result was compatible with a West European Hunter-Gatherer (WHG[9]) ancestry

Can this please be clarified?

Is it now thought that Cheddar Man really did belong to Haplogroup U5 or really did not belong to this group?

(It's not obvious to the lay reader whether West European Hunter-Gatherer ancestry rules out membership in Haplogroup U5 or is compatible with it.)

thanks -- 189.60.63.116 (talk) 02:18, 8 February 2018 (UTC)

We don't know, because the recent "information" on this is not based on a publication but entirely on a Channel 4 television program. There is nothing to report until they publish their study. To answer your question, I believe U5 is correlated with WHG, but we cannot expect any population, even a Mesolithic one, to have just one haplogroup: this would indicate a very serious population bottleneck in the recent past: so while U5 might "indicate" WHG, neither does it establish it, nor would non-U5 be sufficient to establish non-membership in WHG. Identifying "ancestry" based on haplogroups was just the best they could do back in the 1990s, but we have much better tools now, and the popular reliance on mt/Y haplogroups stands in no relation to the quality of results that can be expected in modern studies. This does not translate to, as the NYT seems to think, "10% of British people are WHG and the remaining 90% aren't WHG". This is just nonsense.

About 10% of Europeans have U5, which might be an indication that roughly 10% of European ancestry is WHG derived. In other words: I would recommend removing the entire "U5" part as a 1990s red herring. Fwiiw, U5 is more frequent (higher than 10%, but still lower than 50%) among Basques and Finns, suggesting that Neolithic and Indo-European admixture was weaker in these regions. --dab (𒁳) 06:16, 8 February 2018 (UTC)

Yes, Basques, Estonians, Sami and Finns are shown to have some of the highest Mesolithic hunter-gatherer ancestry among native Europeans, as per Haak et al, 2015. Also, Western hunter-gatherer, Mesolithic Europeans have only been found to have Y-chromosome haplogroups I and C, with I being specifically only a Caucasoid and European/Eurasian subclade, completely restricted to Europeans and those of European descent.Haak et al, 2015 2607:FEA8:1C5F:ECA3:14C0:C1FE:7247:5A2F (talk) 22:08, 11 February 2018 (UTC)
