Abstract

While many studies have highlighted human adaptations to diverse environments worldwide, genomic studies of natural selection in Indigenous populations in the Americas have been absent from this literature until very recently. Since humans first entered the Americas some 20,000 years ago, they have settled in many new environments across the continent. This diversity of environments has placed variable selective pressures on the populations living in each region, but the effects of these pressures have not been extensively studied to date. To help fill this gap, we collected genome-wide data from three Indigenous North American populations from different geographic regions of the continent (Alaska, southeastern United States, and central Mexico). We identified signals of natural selection in each population and compared signals across populations to explore the differences in selective pressures among the three regions sampled. We find evidence of adaptation to cold and high-latitude environments in Alaska, while in the southeastern United States and central Mexico, pathogenic environments seem to have created important selective pressures. This study lays the foundation for additional functional and phenotypic work on possible adaptations to varied environments during the history of population diversification in the Americas.

  • Some of the regions with high-frequency archaic alleles contain genes already identified as adaptively introgressed in Indigenous American populations, including IFIH1/FAP and WARS2 in PEL, and LRRK2/MUC19 in MXL.

    “Some of these regions contain genes that have already been identified as adaptively introgressed in Indigenous American populations, including IFIH1/FAP (Ávila-Arcos et al. 2020) and WARS2 (Racimo et al. 2018), identified in PEL, and LRRK2/MUC19 (Reynolds et al. 2019), identified in MXL.”

    The Discussion (page unavailable) reports a strong signal of selection at MUC19 in the central Mexico population. It does not identify the signal as adaptive archaic introgression or report it for MXL; the retrieved passages also do not identify LRRK2 as a selected gene. (LLM, conf=0.87)

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.
