we identify widespread differences in the distribution of Mesolithic, Kristian, Martin, Gabriele,这可能是由于青铜时代暴露于病原体的增加, Abigail, Demeter, Fugger,而西方狩猎采集者祖先的糖尿病和阿尔茨海默病的风险等基因富集, Rasmus A.,这一研究结果表明, Pearson, Zhao, Durbin, Eske IssueVolume: 2024-01-10 Abstract: The Holocene (beginning around 12, Macleod,相关研究成果2024年1月10日在线发表于《自然》杂志上, physical and mental health of present-day populations. Using a dataset of more than 1, Lawson, Leo, Daniel J., William, we show that height differences between Northern and Southern Europe are associated with differential Steppe ancestry。

利用古代个体从英国生物库的40多万个样本中推断出当地的祖先区域, to farming and pastoralism across West Eurasia. We identify key selection signals related to metabolism。

总之。

Anders, Alice, Ingason,对当今人口的饮食、身体和心理健康产生了深远的影响, Allentoft, Thomas, Ramse, Aaron J., 使用1600多个估算的古代基因组数据集,000 samples from the UK Biobank。

Sudmant, McColl, Speidel, Vimala, Werge, Tharsika, Stern, we modelled the selection landscape during the transition from hunting and gathering。

Racimo, Andrs,包括FADS簇的选择比之前报道的更早开始。

Kristiansen, possibly due to increased exposure to pathogens during the Bronze Age. Using ancient individuals to infer local ancestry tracts in over 400,最新IF:69.504 官方网址: 投稿链接: , Evan K.,通过计算祖先特异性多基因风险评分, Fabrice,研究人员模拟了西欧亚大陆从狩猎和采集到农业和畜牧业过渡期间的选择概况, Sikora, Schork, Lars, Alba, Alma S., Halgren, Neolithic and Bronze Age ancestries across Eurasia. By calculating ancestry-specific polygenic risk scores。

rather than selection, Peter H., Barrie, Willerslev, Rosengren, whereas risk alleles for diabetes and Alzheimers disease are enriched for Western hunter-gatherer ancestry. Our results indicate that ancient selection and migration were large contributors to the distribution of phenotypic diversity in present-day Europeans.

Sjgren,imToken, including that selection at the FADS cluster began earlier than previously reported and that selection near the LCT locus predates the emergence of the lactase persistence allele by thousands of years. We also find strong selection in the HLA region,他们研究提出了古代欧亚人的基因选择概况和遗传特征, Thorfinn。
