    A genetic and linguistic analysis of the admixture histories of the islands of Cabo Verde

    Romain Laurent, Zachary A Szpiech ... Paul Verdu
    The complex histories of social relationships between enslaved and non-enslaved communities and their descendants during and after the Trans-Atlantic Slave-Trade shaped the detailed genetic and linguistic histories of admixture of the islands of Cabo Verde.

    Rapid adaptation to malaria facilitated by admixture in the human population of Cabo Verde

    Iman Hamid, Katharine L Korunes ... Amy Goldberg
    Admixture-mediated adaptation to malaria in a human population demonstrates that detectible signatures in genomic patterns of ancestry can be leveraged to better characterize recent selection in populations with mixed ancestry.

    Admixture into and within sub-Saharan Africa

    George BJ Busby, Gavin Band ... Malaria Genomic Epidemiology Network
    Gene flow analysis reveals that the genomes of most sub-Saharan populations are the result of recent historical admixture events.

    The spatiotemporal patterns of major human admixture events during the European Holocene

    Manjusha Chintalapati, Nick Patterson, Priya Moorjani
    Development of a genomic dating method that leverages ancestry covariance patterns in a single diploid individual reveals the timing of major admixture events during the European Holocene.

    Deep sampling of Hawaiian Caenorhabditis elegans reveals high genetic diversity and admixture with global populations

    Tim A Crombie, Stefan Zdraljevic ... Erik C Andersen
    Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.

    Native American genetic ancestry and pigmentation allele contributions to skin color in a Caribbean population

    Khai C Ang, Victor A Canfield ... Keith C Cheng
    Analysis of 458 Kalinago provides new insights into the population's genetic structure, the contribution of Native American ancestry to skin pigmentation, and the identification of a coding variant in OCA2 with an estimated –8 melanin units effect size.

    On the limits of fitting complex models of population history to f-statistics

    Robert Maier, Pavel Flegontov ... David Reich
    Many published findings about population history that rely on inference of admixture graph models fitted to f-statistics are not robust since the method is generally inappropriate for extracting new information about population history.

    State-dependent representations of mixtures by the olfactory bulb

    Aliya Mari Adefuin, Sander Lindeman ... Izumi Fukunaga
    Responses to odour mixtures are more discriminable in awake, behaving mice due to a combination of dampened responses keeping responses in the linear range and pattern decorrelation, with these two mechanisms operating on different timescales.

    The genomic footprint of social stratification in admixing American populations

    Alex Mas-Sandoval, Sara Mathieson, Matteo Fumagalli
    Social hierarchies resulting from the European colonization of the Americas stratified the population structure, leading to ancestry-related assortative mating and sex bias patterns that can be inferred from the genomes of the populations across the continent.

    Recent shifts in the genomic ancestry of Mexican Americans may alter the genetic architecture of biomedical traits

    Melissa L Spear, Alex Diaz-Papkovich ... Ryan D Hernandez
    Admixture dynamics have recently changed over time in Mexican Americans resulting in an impact on the genetic architecture of phenotypic variation.
