Denisovan genes in Icelanders
From the study "The nature of Neanderthal introgression revealed by 27,566 Icelandic genomes":

Here we examine the effect of this event using 14.4 million putative archaic chromosome fragments that were detected in fully phased whole-genome sequences from 27,566 Icelanders, corresponding to a range of 56,388–112,709 unique archaic fragments that cover 38.0–48.2% of the callable genome. On the basis of the similarity with known archaic genomes, we assign 84.5% of fragments to an Altai or Vindija Neanderthal origin and 3.3% to Denisovan origin; 12.2% of fragments are of unknown origin. We find that Icelanders have more Denisovan-like fragments than expected through incomplete lineage sorting. This is best explained by Denisovan gene flow, either into ancestors of the introgressing Neanderthals or directly into humans.

...

The results indicate that the observed characteristics of Denisovan-like fragments in Icelanders are not compatible with a simple introgression from a Vindija-like group without that population having had prior admixture with a Denisovan-like group (Supplementary Information 3.3.3 and Supplementary Fig. 3.1.1). An equally intriguing scenario that cannot be ruled out is direct admixture from a Denisovan-like group into the common ancestors of non-Africans before the main Neanderthal admixture event

Could you add information on results of the study to the section "Modern humans"?

There also in entry for the study at 2020 in science.

 * You write that Icelanders have 3% of their dna from denisovians. Is it the same 3%.  Or do different people carry a different 3%? Parklandbob (talk) 02:49, 1 May 2023 (UTC)

Possible new specimen
There is a new report of a tooth from Laos identified by the authors as Denisovan. I am a little conflicted over whether this should be listed as a Denisovan specimen (and put on the map), or among the 'other fossils that possibly are Denosovan' paragraph. The article itself uses a title without equivocation, but the publisher, Nature, is much more equivocal about the identification in their science news reporting on the report. A survey of a few other sources that are usually decent at reporting science news are split more or less equally between buying into the identification and equivocating, with some even throwing some shade on the Xiahu identification (which we list unequivocally as a Denisovan specimen). I personally would prefer waiting to see how scholars in the field treat this in their reviews and the summaries of past discoveries int he introductions of future papers, but given the nature of Wikipedia, somebody is going to put it in before a scholarly consensus becomes evident, so I would rather be proactive in raising the question. Anyone have an opinion on how this should be treated? Agricolae (talk) 20:38, 18 May 2022 (UTC)

 * How about "A lower molar discovered in Tam Ngu Hao 2 cave in northern Laos in 2018 has been identified with high probability as coming from a Denisovan female. A Neanderthal individual is considered less likely but cannot be ruled out. The tooth is dated to between 164 and 131 thousand years ago." Dudley Miles (talk) 22:03, 18 May 2022 (UTC)
 * It seems I overlooked that it has already been added to the article, but inexplicably placed at the end of the 'Demographics' section, which isn't really the proper place for it. Agricolae (talk) 01:53, 19 May 2022 (UTC)

Is this overview in the NYT worth including? https://www.nytimes.com/2024/03/02/science/denisovan-neanderthal-dna.html 136.36.180.215 (talk) 17:08, 3 March 2024 (UTC)
