Icelanders (Icelandic: Íslendingar) are an ethnic group and nation who are native to the island country of Iceland. They speak Icelandic, a North Germanic language. Icelanders established the country of Iceland in mid 930 CE when the Alþingi (parliament) met for the first time.
Alternately, high Denisovan DNA admixture in modern Papuan populations may simply represent higher mixing among the original ancestors of Papuans prior to crossing the Wallace line. Icelanders also have an anomalously high Denisovan heritage, which could have stemmed from a Denisovan population far west of the Altai Mountains.

There have been a number of studies about the mitochondrial DNA haplogroups (mtDNA) in Europe. In contrast to Y DNA haplogroups, mtDNA haplogroups did not show as much geographical patterning, but were more evenly ubiquitous. Apart from the outlying Saami, all Europeans are characterised by the predominance of haplogroups H, U and T.
The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans. Neanderthal-derived DNA has been found in the genomes of most or possibly all contemporary populations, varying noticeably by region.
The DNA also showed strong affinities with all existing Indigenous American populations, which indicated that all of them derive from an ancient population that lived in or near Siberia. [33] Linguistic studies have reinforced genetic studies, with relationships between languages found among those spoken in Siberia and those spoken in the Americas.
