The Contribution of Neanderthals to Phenotypic Variation in Modern Humans

Open access
Dannemann, Michael, Kelso, Janet·2017·The American Journal of Human Genetics

Abstract

Assessing the genetic contribution of Neanderthals to non-disease phenotypes in modern humans has been difficult because of the absence of large cohorts for which common phenotype information is available. Using baseline phenotypes collected for 112,000 individuals by the UK Biobank, we can now elaborate on previous findings that identified associations between signatures of positive selection on Neanderthal DNA and various modern human traits but not any specific phenotypic consequences. Here, we show that Neanderthal DNA affects skin tone and hair color, height, sleeping patterns, mood, and smoking status in present-day Europeans. Interestingly, multiple Neanderthal alleles at different loci contribute to skin and hair color in present-day Europeans, and these Neanderthal alleles contribute to both lighter and darker skin tones and hair color, suggesting that Neanderthals themselves were most likely variable in these traits.

  • The results presented in this study argue for a potential contribution of Denisovan variants to immune-related phenotypes amongst early modern humans in the region, potentially favouring adaptation to the local environment.

    “While further experimental validation of our observations is necessary in order to characterise the genome-wide impact of archaic introgression, the results presented in this study argue for a potential contribution of Denisovan variants to immune-related phenotypes amongst early modern humans in the region, potentially favouring adaptation to the local environment [15, 22].”

    From Denisovan introgression has shaped the immune system of present-day Papuans (2022) · cites this paper as [15]

    The Introduction (page unavailable) reports adaptive introgressed variants in immunity-related genes, which supports the general possibility of archaic contributions to immune adaptation. But the Discussion (page unavailable) describes this paper’s analysis as testing Neanderthal alleles in present-day Europeans; it does not establish a Denisovan contribution to immune phenotypes among early modern humans in the citing study’s region. (LLM, conf=0.82)

  • For psychiatric traits, tobacco use disorders trend towards enrichment (1.2-fold enriched, q = 0.23), while introgressed variants are depleted for contribution to personality-related functions (1.4-fold depleted, q = 0.07).

    “For psychiatric traits, tobacco use disorders trend towards enrichment (1.2-fold enriched, CI: 1.0-1.5, q = 0.23), consistent with previous observations, while introgressed variants are depleted for contribution to personality-related functions (1.4-fold depleted, CI: 1.1–1.8, q = 0.07, Fig. 2E)3,4.”

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as [4]

    The Discussion reports that Neanderthal alleles contribute more variation to smoking status than comparable non-archaic alleles, supporting a broad connection with smoking. It does not establish an enrichment for tobacco use disorders or give the claimed 1.2-fold estimate and q-value. The searched passages also do not report depletion of personality-related functions or its 1.4-fold estimate and q-value. (LLM, conf=0.84)

  • Introgression from extinct Neanderthal and Denisovan human species contributes to the genetic pool of modern human populations and their phenotypic spectrum.

    “Introgression from extinct Neanderthal and Denisovan human species has been shown to contribute to the genetic pool of modern human populations and their phenotypic spectrum.”

    From Denisovan and Neanderthal archaic introgression differentially impacted the genetics of complex traits in modern populations (2022) · cites this paper as [16]

    The Introduction states that Neanderthal interbreeding contributed DNA to present-day non-Africans, and the Discussion reports phenotypic variation linked to Neanderthal introgression. The paper does not establish the same claim for Denisovan introgression; Denisovan DNA appears in a cited study and a haplotype-tree method, not as a finding of this analysis. Page numbers were not provided in our copy. (LLM, conf=0.88)

  • Signatures of archaic introgression have been reported in genes associated with hair and skin pigmentation, immunity, neoplasms and metabolic traits, and male sterility.

    “Additionally, signatures of archaic introgression have been reported in genes associated with hair and skin pigmentation, immunity [16, 17, 19, 20, 22], neoplasms and metabolic traits [19, 23, 24], and male sterility [17, 18].”

    From Denisovan and Neanderthal archaic introgression differentially impacted the genetics of complex traits in modern populations (2022) · cites this paper as [16]

    The Introduction (page unavailable) reports introgressed variants in genes related to immunity, skin and hair pigmentation, and metabolism. The Results (page unavailable) also identify Neanderthal haplotypes associated with pigmentation. The cited paper does not report neoplasms; male sterility is attributed to different citations in the citing sentence. (LLM, conf=0.86)

  • Several studies have associated Neandertal-introgressed genetic variants with variability in phenotypes in modern humans, such as immunity, metabolism, adaptation to environmental conditions, and neurological and behavioral phenotypes related to depression and addiction.

    “Several studies have associated Neandertal-introgressed genetic variants with variability in phenotypes in modern humans, such as immunity, metabolism, and adaptation to environmental conditions, like temperature and sunlight, as well as neurological and behavioral phenotypes related to depression and addiction [17–20, 51].”

    From Neandertal Introgression Sheds Light on Modern Human Endocranial Globularity (2019) · cites this paper as [51]

    The Introduction reports prior findings on introgressed variants related to immunity, metabolism, adaptation, and depression; the Discussion reports associations with mood and smoking status and suggests a link to sunlight exposure (pages unavailable). The paper does not establish an association with addiction specifically, and its sunlight-adaptation interpretation is speculative rather than a demonstrated response to environmental conditions such as temperature.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
