Genome-wide data on genetic variation are now available for multiple primate species and populations, facilitating analyses of evolutionary history within and across taxa. One emerging theme from these studies involves the central role of admixture. Genomic data sets indicate that both ancient gene flow following initial taxonomic divergence and ongoing gene flow at current species boundaries are common. These findings are of particular interest given evidence for a complex history of admixture in our own lineage, including examples of ecologically driven adaptive introgression. Like other aspects of human biology, studies of nonhuman primates thus provide both comparative context and a living model for understanding admixture dynamics in hominins. We highlight several open questions that could be addressed in future work.
目前，多种灵长类物种和种群的全基因组遗传变异数据已经可用，这为在分类内和跨分类进行进化历史分析提供了便利。这些研究中的一个新兴主题涉及混合的核心作用。基因组数据集表明，在最初的分类分歧之后，既有古老的基因流，也有当前物种边界的持续基因流，这是很常见的。鉴于我们自身谱系中存在复杂的混合历史的证据，包括生态驱动的适应性渐渗的例子，这些发现尤其有趣。与人类生物学的其他方面一样，对非人类灵长类动物的研究为理解人类的混合动态提供了比较背景和活体模型。我们强调了未来工作中可能解决的几个开放性问题。
