The genetic history of Greenlandic-European contact
Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.
Full frame distilled prediction
Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Abstract
The Inuit ancestors of the Greenlandic people arrived in Greenland close to 1,000 years ago.1Gulløv H.C. The nature of contact between native Greenlanders and Norse.J. North Atlantic. 2008; 1: 16-24Crossref Google Scholar Since then, Europeans from many different countries have been present in Greenland. Consequently, the present-day Greenlandic population has ∼25% of its genetic ancestry from Europe.2Moltke I. Fumagalli M. Korneliussen T.S. Crawford J.E. Bjerregaard P. Jørgensen M.E. Grarup N. Gulløv H.C. Linneberg A. Pedersen O. et al.Uncovering the genetic history of the present-day Greenlandic population.Am. J. Hum. Genet. 2015; 96: 54-69Abstract Full Text Full Text PDF PubMed Scopus (58) Google Scholar In this study, we investigated to what extent different European countries have contributed to this genetic ancestry. We combined dense SNP chip data from 3,972 Greenlanders and 8,275 Europeans from 14 countries and inferred the ancestry contribution from each of these 14 countries using haplotype-based methods. Due to the rapid increase in population size in Greenland over the past ∼100 years, we hypothesized that earlier European interactions, such as pre-colonial Dutch whalers and early German and Danish-Norwegian missionaries, as well as the later Danish colonists and post-colonial immigrants, all contributed European genetic ancestry. However, we found that the European ancestry is almost entirely Danish and that a substantial fraction is from admixture that took place within the last few generations.
